What does service AWD light mean?
The service AWD (All-Wheel Drive) light is an indicator on your vehicle's dashboard that alerts you to an issue with your all-wheel drive system. When this light illuminates, it signals that there is a problem that requires attention from a mechanic or technician.
Understanding the Service AWD Light
The service AWD light is part of your vehicle's warning system, designed to notify you of potential problems with the all-wheel drive (AWD) components. The AWD system is responsible for distributing power to all four wheels, providing improved traction and stability in various driving conditions.
When the service AWD light turns on, it indicates that the vehicle's computer has detected an issue with one or more of the AWD system's components. This could be related to the transfer case, differential, wheel speed sensors, or other AWD-specific parts.
Potential Causes of the Service AWD Light
There are several possible reasons why the service AWD light may illuminate on your dashboard. Some common causes include:
- Malfunctioning wheel speed sensors: These sensors monitor the speed of each wheel and provide data to the AWD system. If one or more of these sensors fails, the service AWD light may turn on.
- Issues with the transfer case: The transfer case is responsible for distributing power to the front and rear axles. Problems with the transfer case, such as a fluid leak or mechanical failure, can trigger the service AWD light.li>
- Differential problems: The front and rear differentials allow for different wheel speeds, which is essential for proper AWD operation. Differential issues, such as a fluid leak or wear and tear, can cause the service AWD light to illuminate.
- Electrical or wiring problems: Faulty wiring or electrical components in the AWD system can also lead to the service AWD light turning on.
If the service AWD light is on, it's important to have the issue diagnosed and addressed as soon as possible to prevent further damage to your vehicle's AWD system.
What to Do When the Service AWD Light Is On
When the service AWD light illuminates, the best course of action is to have your vehicle inspected by a qualified mechanic or technician. They will use diagnostic tools to identify the specific problem and provide the necessary repairs. Ignoring the service AWD light can lead to more severe and costly issues down the road, so it's crucial to address the problem promptly.
In the meantime, you may still be able to drive your vehicle, but it's important to exercise caution and avoid situations that would heavily rely on the AWD system, such as off-road driving or driving in severe weather conditions. Consult your owner's manual for specific instructions on how to proceed when the service AWD light is on.
What problem can AWD warning lights have?
The AWD warning light typically indicates a problem with your vehicle's all-wheel drive system. This could be due to low fluid levels, sensor malfunctions, or mechanical issues within the drivetrain.
How do I know if my AWD system is bad?
AWD issues manifest as noise (crunching, whining, grinding noises), burning smells, difficulty moving the wheel, and shuddering while speeding up or slowing down.
What can go wrong with AWD?
But because AWD greatly reduces wheelspin when accelerating, it's easy to overestimate how much traction there is and drive too fast for the conditions. Do that and you might find yourself sailing off the outside of a corner or through an intersection when trying to stop for a red light.
What causes an AWD service light to come on?
Failing mechanical part: A defective driveshaft, differential, or transfer case can also cause the AWD light to come on. Check to see if my car is AWD or fwdThe Check Engine Light and AWD Light came on together on myWhen the check engine.
Can you drive with AWD on?
All-wheel drive uses all four wheels to power the vehicle. This increases traction, enabling you to drive over terrain and road conditions that a conventional two-wheel drive vehicle cannot. The AWD system is active all the time and requires no input from the operator.
Why is AWD so expensive?
One reason is simply the extra weight of the equipment needed to drive four wheels: You may be using two-wheel power most of the time, but you are carrying the weight around all the time. Another reason is the added drivetrain energy loss when the system is driving four wheels.
What is the meaning of AWD service?
All-wheel drive service is just like a 4wd system, except for the fact that, like it's name, the system is full time 4wd.
Is it safe to drive with the service AWD light on?
Continuing to drive the vehicle while ignoring the illumination/flashing of the TPMS warning light is dangerous because a tyre may burst which could lead to an accident. Take appropriate measures as soon as possible.
How often should AWD be serviced?
Required Service for AWD Vehicles
"Severe service" as defined by the automaker, could have you replacing fluids every 15,000 miles or sooner. If you frequently enjoy taking your four-wheeler out in the rough for a little rock climbing, you'll need to inspect and replace the fluids more often.
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.
