ABS light on GM vehicles?

When your Chevrolet ABS light stays on while driving, it could mean that the anti-lock brake system (ABS) is malfunctioning. A fault code gets stored in thebrake system (ABS) is malfunctioning. One of the most common problems that trigger Chevy ABS light is a bad ABS wheel speed sensor at one of the wheels.

  • Turn the ignition to the “II” position and check the ABS dash light. If the ABS dash light comes on and stays lit, and none of the ABS wires are damaged, it is likely that there is a partial failure in the ABS sensor. For specific information about GMC ABS braking systems, consult the particular vehicle’s manual (see Resources).

What cause the ABS light to come on?

The four common reasons that typically cause this light to turn on include a malfunctioning ABS module, low levels in the fluid reservoir, broken wheel speed sensors, or the system is turned off. Your ABS actually shares some important components with another system in your vehicle: your traction control system.

Is it OK to drive with ABS light on?

It’s Safe To Drive Carefully With The ABS Light On. You can still drive the car with your ABS light on, because it does not impact normal braking. However, we wouldn’t recommend you do this because your ABS system helps to control stopping, and it can be dangerous to be driving without it.

What causes the ABS and brake light to stay on?

An ABS warning light that comes on and stays on could signal a problem with various components in and related to the anti-lock brakes. For instance, special sensors monitor the speed of the wheels. If one or more of these wheel speed sensors are inoperative or defective, the ABS warning light will remain on.

How do you reset the ABS light on a GM?

Access the parking brake, found in the footwell on the driver’s side. Turn it on and off multiple times, usually three or four. The ABS light should go off, which indicates that it has been reset.

How much does it cost to fix an ABS sensor?

The average ABS wheel speed sensor replacement cost is between $200 and $400 per sensor, depending on the car model and labor costs. You can expect to pay about $100 to $150 for the wheel speed sensor and another $100 to $300 for the labor.

How much does it cost to fix ABS light?

Many ABS components are very accessible, so labor for most repairs will not run high typically in the $100 to $150 range. A typical ABS sensor will cost about $80 to $125 however, on some makes and models the sensor is part of a hub/bearing assembly (GM, Ford, some others) and the price will rise to around $350.

Does ABS light affect transmission?

The ABS sensors are related to the brakes. A bad sensor will make the ABS light to come on or the brakes will become unresponsive or possible even lock up. If your transmission is acting up with shifting at slower speeds, it could be a speed sensor or possibly the alternator with leaky diodes affecting the sensors.

How long can I drive with ABS light on?

When your ABS light comes on it doesn’t mean your vehicle isn’t safe to drive from point A to point B. The car will still function as normal, it will start up just fine and drive how it always has and your brakes will work as well.

Can low battery cause ABS light to come on?

Problem Description A weak battery can cause the ABS light to turn on. A brake light that is not working or has burned out can also cause the ABS light to illuminate.

What does the ABS light mean on a Chevy truck?

When your Chevrolet ABS light stays on while driving, it could mean that the anti-lock brake system (ABS) is malfunctioning. A fault code gets stored in thebrake system (ABS) is malfunctioning. A fault code gets stored in the ABS module. Your vehicle may require a longer distance to stop.

Can Dirty brake fluid cause ABS light to come on?

#2 – Unresponsive Hydraulic Pump or Valve One of the causes of this internal wear could be the dirt brake fluid. This could make ABS light to come on.

How do you turn off the ABS on a Chevy Silverado?

To disable the abs system on chevy silverado is an easy job, that requires basically no tools, or maybe a fuse puller. You just need to locate the abs fuse and remove it from the fuse box.

What are the symptoms of a bad ABS module?

Signs Of A Faulty ABS Module

  • The ABS Warning Light Glows. This is the most common sign of problems with the ABS system.
  • The Brakes Lock Up. The ABS system is specifically designed to prevent any wheel from locking up during heavy braking.
  • An Unresponsive Brake Pedal.
  • Increased Pedal Effort.
  • Speedometer Failure.

Will disconnecting battery reset ABS light?

Resetting Your ABS Dashboard Warning Light Step One: Disconnect the positive cable from your car battery. Then, hold down the brake pedal to drain the vehicle’s electrical system. This will result in a reset of the car’s central computer. If there’s no remaining problem with the system, this should reset the light.

Why Is the ABS Light On?

CARS.COM is a website dedicated to automobiles. ABS is an abbreviation for antilock braking system, and if the ABS warning light illuminates in your car’s instrument cluster, it implies that the antilock system has been deactivated as a result of a problem with the vehicle’s computer. Related: What You Should Know About the ABS System The ordinary brakes on your vehicle should function normally, but the antilock braking system, which keeps the wheels from locking up when braking, will not function.

All cars manufactured after 2012 are obliged to feature stability control, which includes both anti-lock braking systems and traction control.

Every time you start your car, the ABS light (which is normally yellow, amber, or orange) should momentarily illuminate as part of a system check to ensure everything is working properly.

If your vehicle is equipped with ABS, sensors fitted on each wheel measure the speed at which the wheels are spinning.

ABS is designed to intervene by rapidly “pumping” the brakes at the wheel that is locking up, causing it to spin and allowing the driver to maintain control of the brakes and steering while still maintaining control.

  • System failure due to a blown fuse
  • A wheel-speed sensor that has been damaged or covered by road grit
  • A damaged or covered wheel-speed sensor It is possible that a wire has been severed between the sensors and the ABS controller. An ABS controller that has failed to function properly

When a pump and valve that provide the proper amount of braking fluid pressure to each wheel to avoid locking fail, an ABS sensor warning light will illuminate. When a pump and valve fail, an ABS sensor warning light will illuminate. When the red warning light for the standard brakes illuminates, it often indicates that your car is losing braking fluid or that the brakes are so worn that you aren’t getting the stopping force you should. If you find yourself in either of those scenarios, you should seek quick treatment and maybe undertake repair work.

Chevy Silverado: ABS Light Meaning & Diagnosis

The ABS light on your Chevrolet Silverado illuminates when the vehicle fails a self-diagnostic cycle. When it is activated, it signifies that the Silverado does not have Anti-Lock brakes, which are important for safety. When braking, your Silverado’s anti-lock braking system (ABS) makes use of a network of sensors to calculate wheel speed. The system will apply the greatest amount of braking to a wheel that is starting to lock up in order to prevent the vehicle from sliding. A vehicle will slow down more quickly if its wheels are spinning rather than if they are locked.

ABS also gives you the ability to control the car as it is slowing down, and it has been around for so long that many drivers have never driven a vehicle that did not have the technology.

Is it Safe to Drive Your Silverado?

The ABS light is distinct from the brake warning light on the car’s dashboard. A malfunctioning physical braking system signifies that your Chevrolet Silverado is hazardous to drive, and the brake light illuminates to warn this. Yes, you are permitted to drive your Silverado with the ABS light illuminated. Is it safe to use? Particularly hazardous is driving when it is pouring, snowing, or the road surface is loose or uneven. It is also less convenient. As a result, we urge that you get the ABS system repaired as soon as feasible.

Chevy Silverado ABS Light On Causes

A decent code scanner will frequently be able to tell you which portion of the ABS system is malfunctioning. This information will not be provided by every OBDII scanner, however. A good one will take care of you. In most cases, car parts retailers will provide you with a free scanning service that they would be pleased to let you take use of. The following are the three most prevalent reasons for the ABS light to illuminate:

1.Wheel Speed Sensor

The wheel speed sensors are in charge of monitoring the wheel speed and transmitting that information back to the computer system for analysis. If one of the wheels is moving more slowly than the others, it is on the verge of locking up completely. The anti-lock braking system (ABS) is then activated on that wheel to prevent it from locking. When this sensor is no longer transmitting a signal to your Silverado’s anti-lock braking system, the system is no longer operating correctly, and the ABS light will illuminate on the dash of your vehicle.

2.ABS Module

They are in charge of monitoring the wheel speed and transmitting that information back to the vehicle’s control computer system. One of the wheels is on its way to locking up if one of them is moving more slowly than the other three. As a result, the ABS is activated on that particular wheel to prevent it from locking. It is no longer operating correctly if this sensor is no longer delivering signals to your Silverado’s anti-lock braking system, and the ABS light will illuminate on the dashboard.

3.ABS Fluid Level

The ABS light will illuminate if the fluid level in the ABS lines is too low to maintain pressure in the lines. The ABS will no longer be able to physically activate if the pressure is not maintained.


It is not recommended that you ignore the ABS light on your Chevy Silverado. The majority of the time, the wheel speed sensors will be the ones that set off the alarm. If you have anything to add, please leave a comment in the section below the article. Wishing you the best of luck!

ABS Light

I have a 2017 that has a 6 on it “The lift, which was installed 2 months ago, and the rest of the details can be seen on the left-hand side of the page or in my build page, which is linked in my signature. The other weekend, while pulling a ’87 Chevy back from Alabama, I received a slew of error codes all at once. I will make every effort to be as specific as possible in order to keep guessing and questions to a minimal. These are the codes that were used: StabilitracTrailer In addition, the ABS light is on.

  1. While this is going on, I’m experiencing other issues: I’m not able to use the cruise control, but the trailer lights and brakes are operational.
  2. I switched off the truck for about 4 minutes, and the codes disappeared (I tweaked the wires to try if I could get the codes to return, but that didn’t work), then they reappeared a few of miles down the road.
  3. We were traveling at 80 mph on a road that was “wavy,” not filled with potholes.
  4. As a result, I traveled a few hundred kilometers to that location as the two of us discussed potential scenarios in our imaginations.
  5. We arrived in Michigan, stopped for gas, and reset the codes; they did not return for the following 40 minutes, despite the fact that we were on flat terrain (we left the truck off at my friend’s house).
  6. When I got there, I sat down and reset the codes on my computer.
  7. My journey to my home (2 1/2 hours away) began until I reached around two miles without any codes, then there they were once more.

My volt meter was reading near nine when I got home, although it should have been reading about fourteen.

As a result of disconnecting the trailer and receiving the codes back, I am confident that the problem is not related to the trailer’s electrical system.

The vehicle rises and returns far more than it would typically do when traveling at 80 mph on a highway while towing.

The 6th is the most important “It’s possible that lift is causing the wires to lose connection sporadically, but it happened on both wavy and absolutely flat roads.

(It’s most likely not.) 3 ) Is it the ground near the speaker in the dash on the driver’s side of the vehicle?

(That was discovered by my friend as he was looking for a possible solution while I was going through Ohio) (Or is it simply a case of my being able to place the blame on Ohio?) It all started when I was traveling there, and we all know how Ohio is when it comes to weather.

During the day today, I’m going to drive around without the trailer connected just to see what happens. My money says it’s coming back, but why does it even state “service trailer” when it’s clearly not?

What does the ABS light mean on a Chevy Silverado?

Asked in the following category: General The most recent update was made on June 24th, 2020. The ABS light on your Chevrolet Silverado illuminates when the vehicle fails a self-diagnostic cycle. When turned on, it signifies that theSilverado does not have Anti-Lock brakes, and hence does not have the added safety that they give. The system will apply the greatest amount of braking to a wheel that is starting to lock up in order to prevent the vehicle from sliding. Failure of the anti-lock braking system (ABS) front wheel speed sensors is described in detail in the following section.

  • What is the procedure for turning off my ABS light?
  • Holding down the “Set” button for around 5 seconds will reset the light and turn it off completely.
  • Furthermore, is it safe to drive a car with the ABS light illuminated?
  • Remember that if both the ABS and Brake System warning lights turn on simultaneously while you’re driving, you must stop your car or truck as soon and safely as possible and call for a tow truck to come pick you up.
  • A defective wheel speed sensor is one of the many possible causes of the ABS light to illuminate and remain illuminated.
  • The ABS light may illuminate as a result of the damage to the wheel speed sensor.

Chevrolet Silverado Pickup Trucks Recalled for Faulty ABS Indicator Light

The 9th of December, 2021 Current status: GM has resolved the issue with 10137 2019-2020 Chevrolet Silverados that were experiencing ABS problems. Eleven cars have been judged unreachable, and an additional two vehicles have been excluded from the Silverado antilock brake system recall as a result of this determination. July 17, 2020 – Pleasanton, California General Motors (NYSE:GM) has issued a recall for 12,200 Chevrolet Silverado pickup trucks because the vehicle’s anti-lock braking system (ABS) may fail to warn the driver that there is a problem, increasing the danger of an accident in the process.

  • Trucks in the medium-duty segment include the Chevrolet 4500HD Silverado Medium Duty trucks, the Chevrolet 5500HD Silverado Medium Duty trucks, and the Chevrolet 6500HD Silverado Medium Duty trucks.

Recall summary

Chevrolet said on May 29 that some 2019-2020 ChevroletMedium Duty 4500HD/5500HD/6000 HD trucks do not comply with a federal requirement requiring the ABS light to illuminate during specific types of breakdowns. Numerous control modules are used by vehicles to run many different components of the vehicle. The General Motors company groups several of these modules into a single unit known as the Body Control Module (BCM), which is responsible for coordinating a variety of tasks in the vehicle, such as the speedometer, the instrument panel, and chime warnings.

These two systems must interact with one another in order to ensure the driver’s safety.

It is possible that the ABS light will not illuminate in the recalled cars if the BCM and EBCM are unable to communicate with each other. This implies that if there is an issue with the ABS, the driver will not be warned of it.


It is critical for drivers to be aware of any issues that may arise with their anti-lock brake system. Driving without the anti-lock brake system (ABS), particularly in severe weather, can be risky since the vehicle may not manage braking on slick terrain in the manner in which it should. When a car slides, the tires lose contact with the road and the driver loses control of the vehicle, increasing the likelihood of a collision.

The repair

A software update for the BCM is required for the affected vehicles. GM tells owners in itsowner notification letter that the update itself may take longer than expected “due to service scheduling constraints.” The update itself should take around 35 minutes. The fix is now accessible and is completely free of charge.

AAMCO Keller Blog

AAMCO of Keller, TX is ready to assist you if your vehicle’s ABS or Traction Control lights are illuminated. Find out why your ABS and traction control lights are illuminated and what you can do about it. Since the 2012 model year, traction control has been standard on all automobiles and light trucks, and many vehicles from previous years that had antilock brakes were also equipped with traction control systems. This is due to the fact that traction control is integrated into the antilock brake system (ABS) and employs the same wheel-speed sensors to detect tire slippage when the vehicle is being driven.

Unlike traction control, which maintains traction while accelerating, and anti-lock braking systems (ABS), which do the same when braking, electronic stability systems compare the vehicle’s trajectory to the direction in which the driver appears to want the vehicle to go, and brake individual wheels to keep the vehicle on track.

  1. They are housed at the base of each wheel and operate in a harsh environment that includes potholes, water, snow and other debris.
  2. When there is an issue with the system, a dashboard warning light will normally appear, indicating that traction control has been deactivated and, in certain situations, that the anti-lock braking system has been disabled as well.
  3. Sensors that measure wheel speed are meant to detect when one of the vehicle’s drive wheels is spinning faster than the others, indicating that the vehicle is losing grip or slipping.
  4. When the spinning wheel is stopped, the power can be transferred to the other driving wheel or wheels that have higher traction on the road.
  5. Sometimes the warning light will illuminate because the wheel-speed sensors are coated with road filth or debris, which causes the warning light to illuminate.
  6. When the traction control warning light remains illuminated, it indicates that you are not receiving any assistance from the system in controlling traction, and the system should be examined.
  7. The majority of wheel slippage may be avoided simply easing off on the gas pedal during acceleration.

In most cases, a scan tool is required to read the trouble code that prompted the warning light in order to diagnose the problem. Scan tools can assist in determining what the problem is (for example, a defective speed sensor or connection) and at which wheel it is occurring (s).

Can I drive with the traction control warning light on?

You shouldn’t be alarmed if the traction control light illuminates while you’re driving but no other warning lights are glowing at the same time. Choose an appropriate location to pull over, turn off your car, and then restart it. If the warning light was triggered by a glitch in the TCS system, it should switch off and remain off when you restart the engine. If the light turns back on, it’s most likely time to call a repair and have the system evaluated. Until the problem is resolved, drive slowly and avoid strong acceleration, which might cause the wheels to slip out from under you.

If the TCS and ABS warning lights illuminate simultaneously, as well as the red main brake warning light, you should refrain from driving the vehicle until the problem has been resolved.

Towing your vehicle to a repair facility is a good idea.

The exact issue code might assist in determining which component is generating the failure, as well as its precise placement on the vehicle.

What if the ABS Light Stays On?

What happens if the ABS light remains illuminated? It’s amazing how a small symbol appearing on your dashboard unexpectedly can generate such a horrible feeling in your stomach. That annoying little light is a warning that something is wrong, you know. And how much more terrifying it is when the warning bulb that has just illuminated is associated with the most critical safety mechanism on your vehicle: your brakes. Is there anything you should do if the ABS light on your dashboard comes on? What exactly does the ABS light mean?

  • A vehicle’s anti-lock braking system (ABS) keeps the wheels from locking up when a driver presses on the brake pedal in an emergency circumstance or when driving on a slick or muddy surface.
  • The ABS also helps the driver keep control of the steering system by allowing them to continue rotating while the vehicle is in motion.
  • When a vehicle is first started, the ABS light will on for a brief period of time when the system performs a diagnostic self-check.
  • However, under typical circumstances, the light comes on momentarily, along with numerous other warning lamps, and then goes out completely.
  • In what situation does the ABS warning light illuminate?
  • For example, unique sensors measure the rotational speed of the wheels.
  • If there is an issue with the wiring, the situation is the same.

The warning light may also illuminate if a fuse is blown or if the brake fluid level in the brake master cylinder is low, among other things (or in the ABS reservoir if the vehicle is so equipped).

The majority of drivers will prefer to have their car inspected by a repair shop when their vehicle’s anti-lock braking system (ABS) displays a malfunction.

In truth, if the problem is caused by a lack of braking fluid, the solution is straightforward.

The fact that not all brake fluids are compatible with one another means that it is critical that the correct fluid be used in a vehicle.

In addition, while replacing a blown fuse is not a difficult procedure, determining why the fuse may have blown might be challenging.

Some automobiles’ warning lights will flash a number of times before becoming illuminated permanently.

It is important to do a diagnostic scan on other cars using specific equipment and to have knowledge of how to interpret the information from the vehicle’s computer.

Next, it is required to identify the precise reason of the malfunction.

Fortunately, even if the ABS warning light illuminates and no other warning lights are on, the brakes will continue to function normally.

However, in an emergency or on a slick road, the ABS will not operate and will not prevent the wheels from locking up.

Furthermore, if there are any additional warning lights illuminated, it is possible that there is a problem with the general braking system, which indicates that the vehicle should not be driven.

Make sure that you have a skilled technician examine and assess the cause of the ABS light coming on in your vehicle.

Light truck ABS malfunctions

However, a review of technical bulletins and anecdotal evidence would appear to imply that light trucks are more frequently affected by ABS difficulties than other vehicles. The fact that light vehicles, and the inclination for them to be outfitted with 4WD, complicate the control systems required by ABS systems suggests that it is not all in our heads. An example of such a difficulty is one that involves the 4WD function in particular. A recall campaign was even launched, impacting 4X4 Blazers and S10 pickups from 1991 to 1996 (for Blazers) and 1994 to 1996 (for S10 pickups).

  1. This switch activates the anti-lock braking system module, which then modifies the algorithm to correct for the brake torque supplied to the rear wheels through the powertrain while the vehicle is in four-wheel drive.
  2. As a consequence, inadequate brake pressure is delivered, resulting in increased stopping distance and, perhaps, a crash–which is why the recall was issued in the first place.
  3. In the 1990s, General Motors experienced a problem with their RWAL-equipped GMC and Chevrolet trucks that were equipped with leading/trailing type rear brake shoes.
  4. These indications appeared to indicate to a failure of the electro-hydraulic anti-lock braking system valve, which had previously been identified as having a potential internal failure in the prior investigation.
  5. The telltale evidence of uneven wear, where the top third of the shoes is worn significantly more than the bottom two-thirds, indicated that the shoes were not sliding on the lower tapering shoe mounting block, which was the cause of the problem.
  6. Because of the direction of the drum’s spin, the leading shoes have a self-energizing effect on the band.
  7. When examining the brakes, a technician should use the palm of his hand to tap downward on the top of each brake shoe, starting from the center.

After then, he should tap his foot upward, allowing the shoe to rest in its natural at-rest posture.

Whether new shoes are being placed or the current shoes are being maintained, the mounting block should be greased before use.

It’s important to note that this isn’t always the case.

The wheel speed sensor is the most likely culprit, and it is at the top of the list.

Various environmental factors such as salt water, filth, dust, and physical damage might cause a sensor to fail or to provide intermittent readings, which is potentially more dangerous.

When it comes to automobiles manufactured in 1999 or after, there are two types of wheel speed sensors available.

The resistance of the coil windings may be measured with the ignition key turned off and a digital volt ohmmeter in use.

Typically, manually turning the wheel will result in an alternating current voltage output of roughly 60mv or higher.

Two cables connect this new type of sensor to the computer, and within the sensor is a tiny power source that provides around 0.90 volts back to the computer.

With each passing tooth of the tone wheel tooth that approaches the sensor magnet, the signal voltage should increase to around 1.65 volts.

To inspect a magneto resistive sensor, the technician must first secure the vehicle on jack stands and then back probe the wheel speed sensor with extreme care.

The other wire is responsible for returning signal voltage to the computer.

It is expected that rotating the wheel at a very slow speed would result in signal voltages varying between slightly less than one volt and slightly more than 1.5 volts.

On the direct current signal to the computer, technicians should search for sharp corners that are constant throughout time.

Of course, there are instances when a system will set a variety of issue codes that are associated with the ABS system.

He receives a fault code that instructs him to search in a certain region, but that component turns out to be fine.

In fact, this is exactly the case with various General Motors vehicles from the year 2000, notably the Chevrolet S10, Blazer, Envoy, Jimmy, and Sonoma.

As it turned out, this was the result of a design flaw that caused the wiring harness to be too close to the exhaust manifold during the construction process.

This can result in excessive resistance across the wire, as well as short circuits to the grounding conductor.

The solution is to determine whether or not the harness is positioned close to the manifold and whether or not it is damaged.

These are only a few instances of the sorts of difficulties that ABS issues might provide, particularly in the context of light-duty vehicles.

Trucks that cause problems Codes 61, 62, and 63 can be displayed on 1990-1992 General Motors light trucks equipped with 4WAL ABS systems.

These codes are typically found on vehicles that are three years or older in age.

Because of the small orifices and passageways in the EHCU, it is susceptible to contamination from contaminated fluid.

Whenever all three codes are present at the same time, it is most likely due to an electrical grounding problem, as these switches are grounded through the brake line.

In order to determine whether the contaminated fluid was the source of the problem, the technician should drain the fluid from the reservoir and examine the bottom for signs of sediment. If sediment is found at the bottom of a reservoir, it is likely to be found throughout the entire system.

If the ABS light on your automobile comes on, don’t freak out. There might be a variety of reasons for the light to be turned on in this situation, including:

GM hits the brakes on ABS; antilocks will become options on low-end cars

RICHARD TRUETTAutomotive News Contributor The decision by General Motors to make antilock brakes optional on its entry-level vehicles is another another blow to suppliers who are already battling to keep up with pricing demands and strong competition. However, for General Motors, the adjustment will allow the corporation to better compete with Hyundai and Kia. Korean manufacturers Hyundai and Kia are on a roll, grabbing market share with low-priced automobiles that are jam-packed with goodies.

According to a GM spokeswoman, the money the business saves on antilock brakes, which amounts to around $160 per car, will be utilized in many cases to install CD players and other items that are now available as options.

Most mid-priced and higher-priced automobiles, such as the Chevrolet Impala, Oldsmobile Intrigue, and Buick Regal, can be equipped with antilock brakes and side airbags as part of a safety package.

Maintain the need for antilock brakes on all Cadillacs, Saabs, pickups, sport-utilities, and high-end full-sized vans as standard equipment.

Side-impact airbags should no longer be standard equipment on the Pontiac Aztek and Bonneville, the Buick LeSabre and Rendezvous, the Oldsmobile Bravada, the Chevrolet Avalanche, Tahoe, Suburban, and TrailBlazer, and the GMC Envoy, among other vehicles.

Antilock brakes will still be standard on around 70% of GM’s North American output in 2003, down from over 95% this year, according to GM spokesperson Julie Hamp.

However, because some consumers may still desire antilock brakes as an option, suppliers will not necessarily lose that many sales as a result of this.

Power & Associates in the fall of 2013.

Delphi Corporation, TRW Automotive, and Robert Bosch Corporation are among the companies that GM has purchased antilock braking systems and components from.

Gaut declined to comment on the possible revenue loss or how many antilock systems or components it supplies to General Motors in a given year.

The decision by General Motors will not result in any layoffs or employment reduction at Delphi, according to him.

TRW Automotive, which provides antilock brakes for General Motors’ light vehicles, does not anticipate any negative consequences from the company’s policy shift, according to TRW spokesperson Julie Ballesteros.

The withdrawal of General Motors from antilock brakes might have an impact on the value of TRW’s automotive components business.

“I am perplexed by General Motors’ attitude to depriving its vehicles of these basic features.

“GM isn’t taking the big picture into consideration.

Liability worries, on the other hand, will arise some years down the line.

A set of antilock brakes is offered as an option on the Ford Taurus, Honda Accord, Toyota Camry, and Dodge Intrepid’s base models, and a package of antilock brakes is available on higher-trim variants of each of those cars.

“It is still considered optional equipment.” It is still available to the customer.

Reduced content is part of General Motors Vice Chairman Robert Lutz’s effort to eliminate standard equipment that doesn’t stimulate purchasers’ interest.

“General Motors should be commended for taking the initiative and making ABS mandatory,” said Frank Forkin, an analyst with J.D.

“However, it has really resulted in General Motors being at a cost competitive disadvantage.” According to Forkin, General Motors initially utilized antilock brakes as a marketing tactic.

ABS was the differentiator when it was popular, according to him.
