Solution

1. Preparation

Gather necessary tools and ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent any electrical shorts during repair.

2. Retrieve and Analyze Error Codes

Use the OBD-II scanner to read the error codes stored in the system.
Document any codes related to the traction control or ABS system for further analysis.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensor area.
Check wiring for frays or disconnections.
If damaged, replace the wheel speed sensor with a new one.

4. Check ABS Control Module

Locate the ABS control module, typically found near the master cylinder.
Inspect the wiring harness for any loose connections or damage.
If fault codes indicate a malfunction, consider replacing the ABS module.

5. Verify Brake Fluid Condition

Open the brake fluid reservoir and check the fluid level.
If low, top up with the appropriate brake fluid (DOT 4 or as specified).
Inspect for any signs of contamination; if contaminated, perform a brake fluid flush.

6. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Ensure the switch is functioning by pressing it to toggle traction control on and off.
Replace the switch if it does not operate correctly.

7. Reconnect Battery and Clear Codes

Reconnect the vehicle battery.
Use the OBD-II scanner to clear any stored error codes.
Start the vehicle and check if the traction control light remains off.
