Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the electrical components.

2. Scan for Error Codes

Reconnect the battery.
Use an OBD-II scanner to retrieve any codes related to the traction control system.
Note and document any error codes for further analysis.

3. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris from the sensor area using a cleaning cloth.
Check the wiring harness for frays or disconnections and repair as needed.

4. Check Brake Fluid

Open the hood and locate the brake fluid reservoir.
Ensure the brake fluid is at the recommended level; top up with manufacturer-approved brake fluid if necessary.
If fluid is low, check for leaks in the brake system.

5. Inspect ABS Module

Locate the ABS module, usually found near the brake master cylinder.
Check for loose connections or visible damage on the module.
If corrosion is present, clean the electrical contacts and reconnect.

6. Clear Error Codes

After completing inspections and repairs, use the OBD-II scanner to clear any stored error codes.
Test drive the vehicle to see if the traction control light reappears.
