Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel.
Remove any dirt or debris from the sensor area using a clean cloth.
Check the wiring harness for any signs of fraying or disconnection.
Reconnect any loose connections and securely fasten the wiring.

3. Check Brake Fluid and ABS Module

Remove the brake fluid reservoir cap and check the fluid level.
If low, top off with the appropriate brake fluid as specified in the owner's manual.
Inspect the ABS control module for any visible damage or corrosion.
If error codes indicate a faulty ABS module, it may need replacement.

4. Test Drive and Re-check

Reconnect the battery and start the vehicle.
Perform a test drive to ensure the traction control light does not re-illuminate.
Monitor the vehicle's performance for any signs of traction issues.
