What would cause my AWD light to come on?
As a car owner, seeing the All-Wheel Drive (AWD) light illuminate on your dashboard can be concerning. This warning light indicates that there may be an issue with your vehicle's AWD system, which is crucial for maintaining traction and stability, especially in adverse weather conditions. In this article, we will explore the common causes of the AWD light activation and what steps you can take to address the issue.
Common Causes of the AWD Light Activation
There are several reasons why your AWD light may come on. Understanding these causes can help you diagnose the problem more effectively:
- Low Fluid Levels: The AWD system relies on specific fluids to operate correctly. Low levels can lead to system malfunctions.
- Faulty Sensors: The AWD system uses various sensors to monitor performance. If a sensor fails, it can trigger the AWD light.
- Transfer Case Issues: Problems with the transfer case, which distributes power to the wheels, can cause the AWD light to activate.
- Worn or Damaged Components: Over time, parts of the AWD system can wear out or become damaged, leading to warning lights.
- Electrical Problems: Issues with the vehicle's electrical system, such as wiring or battery problems, can also trigger the AWD light.
Identifying the specific cause of the AWD light is essential for effective repairs. Regular maintenance can help prevent many of these issues from arising.
What to Do When the AWD Light Comes On
If your AWD light comes on, it's important to take the following steps:
- Check Fluid Levels: Inspect the fluid levels for the AWD system and top them off if necessary.
- Inspect for Fault Codes: Use an OBD-II scanner to check for any diagnostic trouble codes that may indicate the problem.
- Consult a Professional: If you're unable to diagnose the issue, it's best to take your vehicle to a qualified mechanic for a thorough inspection.
- Avoid Driving in AWD: If the light is on, avoid using the AWD system until the issue is resolved to prevent further damage.
Taking prompt action can help mitigate potential damage to your vehicle and ensure your AWD system functions properly.
Conclusion
The AWD light is an important indicator of your vehicle's health. By understanding the common causes and knowing how to respond, you can maintain your vehicle's performance and safety. Regular maintenance and timely repairs are key to keeping your AWD system in top shape. If you have any concerns about your vehicle, don't hesitate to reach out to a trusted auto service provider.
Frequently Asked Questions
Why is my car telling me to service all-wheel-drive?
Uh oh, did your All-Wheel Drive warning light come on? This light flashes if the vehicle is driven with tires of differing diameters fitted on the wheels or with an excessively low air pressure in any of the tires.
Why does my AWD keep turning on?
This light will usually come on when the car is first started or after the car is shifted into reverse, and it will stay on until the car is shifted into a forward gear. However, if the light stays on continuously, it means that there is a problem with the AWD system that needs to be fixed.
What is an AWD problem?
If you notice your vehicle becoming increasingly difficult to steer or if it feels less stable on the road, it could indicate a problem with the AWD system. Issues such as tire misalignment, uneven tire wear, or problems with the system's sensors can affect handling.
How to reset service all-wheel drive light?
Think of it as hitting the reset button on your 4WD system. You might start by disconnecting the battery or giving the Transfer Case Control Module (TCCM) a little time off. This can sometimes shake loose any gremlins causing the light to come on. Next, engage the 4WD system and see if it's responding correctly.
At what speed does AWD turn off?

How much does it cost to service an AWD?
The cost of servicing a 4-wheel-drive system can range from $80 to $300, depending on the specific service components and requirements.
Is it safe to drive with AWD on?
On icy or snowy roads, AWD cars had a 13-15% higher impact severity than 2WD cars, which corresponded to an 8-10% increase of impact speed for AWD cars. On dry or wet roads, no differences were found between AWD and 2WD.
Is it expensive to fix AWD?
All-wheel drive (AWD) and four-wheel drive (4WD) systems are more complex and costly to repair than standard front-wheel drive systems. That means your auto insurance rate may be higher for an AWD or 4WD vehicle.
