What Can Cause an AWD System Warning?

The AWD system warning light in a Jeep is usually illuminated when one of the AWD system components has failed or is malfunctioning. Common causes of the light illuminating include low fluid levels, worn parts, faulty sensors, and other mechanical issues.

  • Low Fluids: The AWD system uses transmission fluid to lubricate its components and ensure proper operation. If this fluid level is low due to leaks or regular wear and tear, it can cause the AWD warning light to come on. To prevent it, regularly check the fluid levels and top off as needed.

It can cause the warning light to come on until these parts are replaced with new ones that are properly functioning. Performing routine maintenance tasks, like regularly inspecting for wear and damage, is essential to prevent malfunctions.

  • Faulty Sensors: The AWD system sensors are very sensitive and can easily be damaged if exposed to extreme temperatures or rough terrain while driving.

  • Other Mechanical Issues: There may also be other mechanical issues present within your Jeep’s AWD system that could cause it to malfunction and trigger a warning light on your dashboard. These issues could include loose bolts, electrical wiring problems, etc., which would need immediate attention from qualified mechanics to keep your car running smoothly without any further issues.
