Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to prevent electrical short circuits.
Ensure vehicle is on a flat surface and engage parking brake.

2. Scan for Error Codes

Use an OBD-II scanner to retrieve any fault codes.
Record codes for reference and clear them to see if they return after repairs.

3. Inspect Wheel Speed Sensors

Locate each wheel speed sensor (usually on the wheel hub).
Remove any debris or dirt from the sensor and connector.
Check the wiring for frays or breaks; repair or replace as necessary.

4. Check Brake System Components

Inspect the brake fluid reservoir; ensure it is filled to the recommended level.
Check for any visible leaks in the brake lines or around the master cylinder.
If fluid level is low, top up with the manufacturer-recommended brake fluid.

5. Inspect ABS Module

Locate the ABS module, usually near the brake master cylinder.
Check for any wiring issues or visible damage.
If necessary, test the module with a multimeter for proper voltage output.

6. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Remove the switch and test with a multimeter to ensure it operates correctly.
Replace the switch if it fails the test.

7. Reconnect Battery and Test Drive

Reconnect the negative terminal of the battery.
Perform a test drive to check if the traction control light remains off and the system functions correctly.
