Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Scan and Clear Codes

Use an OBD-II scanner to check for any diagnostic trouble codes.
If codes are present, document them before clearing.
Clear the codes and check if the traction control light returns.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Clean any debris or dirt from the sensors and their connectors.
If damage is found, replace the affected wheel speed sensor with a new one.

4. Check Brake Fluid

Locate the brake fluid reservoir.
Inspect the fluid level; if low, top off with the manufacturer-specified brake fluid.
If the fluid is contaminated, perform a brake fluid flush.

5. Inspect ABS Module and Wiring

Locate the ABS module, typically found near the master cylinder.
Inspect all wiring and connectors for damage or corrosion.
Repair any damaged wiring and ensure all connectors are securely attached.

6. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Test the switch for proper operation using a multimeter to ensure it is functioning correctly.
Replace the switch if it is found to be defective.
