A lot of the time, a flashing 4WD light is no reason to be alarmed, because it simply means that the system is working as designed. On vehicles where four-wheel drive is only activated on demand — that is to say, when traction conditions require it — this light shows up to tell you that it’s been activated.
- When the light flashes continuously for more than 30 seconds it signifies there is a problem somewhere on your drivetrain system and that 4WD has not engaged properly. Once the 4WD mode is engaged successfully, the 4×4 light will shine a solid color, usually orange or green.
What causes 4WD light to come on?
When the 4WD light appears, it is letting you know that there is an issue with the 4WD system and it must be handled promptly. Another reason why this light may occur is an incomplete shift in gears. This is confusing and damaging to the engine and could result in your 4WD service light flashing continuously.
Can I still drive with service 4WD light on?
The 4WD switch light will indicate 2WD or Auto when drive engaged. Cause: If the light stays on, or the ‘Service 4WD System’ message is displayed, there is a problem with the 4WD system. The ‘Service 4WD System’ message does not mean routine maintenance of the 4WD system is required.
What Does 4WD on dash mean?
One manufacturer simply uses a 4×4 Indicator to mean that the vehicle is in 4×4 HIGH. This indicator, 4WD AUTO, states that the vehicle is in AUTO mode. The vehicle will automatically engage 4 wheel drive when a loss of traction is sensed.
What Does 4WD with an exclamation point mean?
4WD Warning Light: This light appears as the characters 4WD with an exclamation mark, and indicates a fault with your 4WD system. If it’s blinking repeatedly, the system is completely disabled due to an overload. If you disengage it and the light remains on, you could have low brake fluid.
Can I drive with AWD light on?
If any malfunction occurs in the AWD system while the engine is running, the warning light will come on. If the warning light blinks rapidly during operation, stop the vehicle with the engine idling in a safe place immediately. Then if the light turns off after a while, you can continue driving.
What causes 4×4 not to engage?
A fourth and final reason why your 4 wheel drive light is flashing and 4WD fails to engage could be due to a faulty signal. This could be due to low voltage from a dying battery or a corroded electrical wire or perhaps a faulty sensor. Could also be a faulty switch on the dash or a blown fuse.
Is it bad to drive in 4WD Auto?
Using Auto 4wd will not hurt anything. It is there and available if the truck detects wheel slippage. But, the hubs are free, so it’s not putting extra load on your transfer case. You don’t want to use 4wd high for long distances on dry pavement.
Why is my all wheel drive warning light on?
The all-wheel drive (AWD) Warning Light is located on the instrument panel. When this light illuminates, the vehicle has detected a problem with the AWD system, or the diameter of the front and rear wheels is different. Tips The AWD Warning Light will illuminate when the vehicle is first turned on.
What does 4×4 low light mean?
The 4×4 Low Light indicates when the four-wheel drive system is enabled. The driver is responsible for turning this feature on and off. The 4×4 Low Light will come on for a moment when the 4×4 Low system is enabled. If the light does not come on or it stays on, have the system serviced as soon as possible.
Why does my 4×4 light blink?
A flashing indicator light is typically caused by wiring or an electrical component like the controller, a faulty motor or fork, a speed sensor, or a position switch. Many 4WD units have an actuator located on the front axle to lock and engage the front axle for 4WD. Check to see if the vehicle is in 4WD.
How do I turn my 4 wheel drive off?
How to Disengage a Stuck Four-Wheel Drive Line
- Check to see if you have manual hubs and that they are in ‘free’ mode.
- Put your vehicle into four-wheel high mode.
- Drive forward for about a quarter of a mile.
- Stop the vehicle and shift from four-wheel to two-wheel drive.
Where is the 4WD actuator located?
It plays a vital role in the part-time 4WD mode vehicle, and thus, proper care should be taken to ensure it is functioning well. Since the actuator is located on the vehicle’s underside, it is prone to scratches or getting wet.
Is Your 4WD Light Flashing? Don’t Panic! Here’s What’s Happening
Is there anything worse than seeing the 4WD light (or a similar 4WD light) on your dashboard blinking and instantly starting to fear that you could be in for a costly repair job? When a warning light shines, it’s never a good indication, but it doesn’t always mean that your four-wheel-drive system has failed. If your vehicle’s 44 light is flashing, consider the following three possibilities that might be taking place.
1. Overheated Transfer Case 4wd selector dial’ data-medium-file=’ data-large-file=’ loading=’lazy’ src=’ alt=’4×4 selector dial’ width=’249′ height=’249′ data-lazy-src=’ srcset=’data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7’>
On SUVs and crossovers equipped with a light-duty four-wheel-drive system that does not include low-range gearing, the design specification does not include provisions for more harsh driving conditions such as deep mud, rock crawling, or snow. If you find yourself spinning your wheels without making any forward progress or stuck to the point where you are unable to move, continuing to press the gas pedal can build tremendous heat within your vehicle’s transfer case, which will damage the transfer case.
If it overheats, it may no longer be able to perform as intended, resulting in the 4WD light flashing intermittently.
It’s a good idea to consult your owner’s handbook to find out exactly what the flashing light signifies in this particular circumstance.
2. Sensor Failure
Several sensors and switches in your vehicle’s four-wheel-drive system provide it with information about anything from the throttle position to wheel speed to transmission speed to the actual positioning of various components. If one or more of these sensors or switches isn’t functioning correctly — either by not communicating any data or by transmitting a reading that is far outside of the normal range — the 4WD light on your dashboard may begin to flash. Talking to your mechanic about if you could be looking at a faulty sensor before concluding that you have a transfer case problem is beneficial before assuming that you have.
3. The System Is Working Normally
Most of the time, a flashing 4WD light is not a cause for concern because it merely indicates that the system is functioning as intended. This light illuminates on cars whose four-wheel drive is only triggered on demand — that is, when traction circumstances need it — to alert the driver that four-wheel drive has been engaged. Similarly, the stability control and traction control lights on your dashboard will illuminate when their respective systems are activated, as will the hazard lights on your side mirrors.

ABS and 4WD lights on
Okay, I’d want to ask you a question. It’s possible that my most recent article was in response to a strange sound that suddenly erupted from the engine of my 2006 XLT after a short trip to the market. It turned out to be a faulty timing chain, which resulted in the destruction of the back part of the motor. We’re back on the road after spending $2800 on a motor. This is something more I’ll include. We’ve been utilizing the same mechanic for three different autos for almost eight years. He has always been fair and truthful in his dealings with us.
- Regardless of the circumstances, I conduct extensive study before committing to any certain course of action or decision.
- It took around 2 weeks after the repair before the ABS light started flashing 6 times every few minutes and the 4WD light started flashing every few minutes.
- It doesn’t matter either way it goes; I’m returning it to the business that performed the repair.
- Thanks!
06 Escape w/ blinking 4wd light AND an ABS light
10:00 a.m. on April 9, 2009 Date of joining: April 2009 Number of posts: 9 I recently experienced the same issue with my 2006 XLT V6. I had recently purchased it used from a dealer and was experiencing issues with it when I received it. Because of the clunking sounds coming from the back every time I turned, they ended up replacing the differential, as well as the wheel bearings, rotors, and a few other components. Consequently, when I noticed these lights illuminated, I assumed they had something to do with the repercussions described above.
Apparently, when the ABS light illuminates and the 4WD light flashes sporadically, the vehicle is in trouble.
This one shows that one of the four-wheel-drive system’s wheels has slid and spun at speeds in excess of 131 kilometers per hour (sorry, I live in Canada).
The only problem was that I never had a wheel slide on the day it happened, which was frustrating. Especially not in excess of 131 kilometers per hour. I’m thinking it’s a bad wheel sensor or something, so if it happens again, I’ll take it back and have them replace it.

4 wheel drive light stuck on
1999 Ford F-150 I have a problem with my 4×4 indicator lights being stuck on both high and low, which prevents my speedometer from getting an accurate reading. As a result of becoming stuck, I placed the truck into 4 wheel low in order to pull it out, and the light has remained on for a week. The 4wheel drive system is not activated. I tried disconnecting and reconnecting the battery three times to reset the computer, but it didn’t work. Any assistance will be much appreciated. kits hacker Posts by Senior Members: 297 Date of joining:Sat, July 26, 2008 9:21 a.m.

- Check the twin electric vacuum solenoids in the firewall and the GEM to see if they are the source of the problem.
- The location is Prince George, British Columbia, Canada.
- I receive this error message rather frequently.

my truck modifications by J Rob« I attempted to disconnect the vacuum solenoids, but the lights remained on.
What exactly is it, and where exactly is it located?

The truck is a 1998 Ford F150 5.4L SC XLT 4X4.
If the clicks are coming from under the center dash, you should suspect your GEM module, which is located beneath the top center dash and communicates with the vacuum solenoids to determine when to open or close the vehicle’s vacuum valves.
The location is Akron, Ohio.
It was suggested to me that it may be on the rear side of the fuse box.

According to the instructions, the GEM that controls 4 wheel drive as well as numerous other features is situated beneath the steering column, on the rear of the bulkhead.
Connect the battery for at least 10 minutes before attempting any manipulations.
Then, with the use of a junction panel, find and disconnect the bulkhead electrical connectors from the instrument panel.
After that, unhook all of the GEM electrical connectors (3).
Replace the old GEM with the new one and reinstall everything in the reverse sequence.
You will need to drive it for a time in order for the computer to recall its parameters and function appropriately once more.
One will provide some light on that aspect of the problem, but there are a variety of other possibilities.
This information was obtained from the Ford workshop handbook.

You may take it to the dealership and ask for a diagnosis, which would cost around $100.00.
If it’s an easy project, consider doing it yourself.
Please keep a mind to always request an A tech to work on your vehicle.
I bring my truck into the dealership once in a while when something strange happens that I can’t fix myself without the specialized tools that only the dealership possesses.

Troubleshoot 4WD Light Flashing
Vehicles with four-wheel drive can be shifted either electrically or manually. Electronic four-wheel-drive cars are equipped with warning lights that illuminate when there is a problem with the system. Different manufacturers utilize different transfer cases and control systems in their part-time 4WD cars, and this is true for their transfer cases and control systems. A flashing indication light indicates that the car is shifting, and this is standard practice. Once the vehicle has been placed in the chosen mode, the light should remain illuminated, indicating that the shift into that mode has been successfully completed.
- Many 4WD units are equipped with an actuator positioned on the front axle, which is responsible for locking and engaging the front axle for 4WD.
- Check to verify if the car is in four-wheel drive ( 4WD ).
- Lift one side of the vehicle’s front end and spin the tire to check for flats.
- If the tire is difficult to turn or becomes locked, the vehicle is in 4WD.
- During this windup, the front tire will spin with tremendous power, causing the front tire to rise off the ground completely.
Wrench light when using 4wd
It is quite difficult to identify a problem on your own unless you have the particular DTC that prompted the wrench light to appear. I can inform you that there aren’t any TSBs that deal with your particular problem. I’m going to mention one SSM that may or may not have anything to do with your worry, so don’t take it as a given that it applies in your situation. In any case, here’s what happened: Intermittent Loss Of Throttle Response in a 2015/2017 Ford F-150 with several warning indicators and/or multiple diagnostic trouble codes is covered by SSM 46829.
Because the Accelerator Pedal Position (APP) Sensor 14A005 harness is wrongly routed below the brake booster and into the brake pedal bracket, this might be the source of the problem.
Before you can correctly route the harness, you must first inspect and replace any broken circuits. If the harness has been properly routed, you can proceed with the regular diagnostic procedures.
