Solution

1. Preparation

Gather tools and parts to ensure a smooth repair process.
Tools Required: OBD-II scanner, socket set, multimeter, brake fluid, tire pressure gauge.
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Retrieve and Clear Diagnostic Codes

Use the OBD-II scanner to read and note any error codes related to the traction control system.
Clear the codes and check if the traction control light returns after a short test drive.

3. Inspect Wheel Speed Sensors

Lift the vehicle and remove the wheels to access the wheel speed sensors.
Check each sensor for physical damage or dirt buildup. Clean or replace as necessary.
Ensure wiring harnesses are securely connected and free of corrosion.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; top it off if low. Look for leaks around the brake lines and master cylinder.
If leaks are present, repair or replace the affected components.

5. Examine ABS Module and Wiring

Locate the ABS module, usually mounted near the brake master cylinder.
Visually inspect the module and wiring for any signs of wear or damage.
Use a multimeter to test the module's electrical connections for continuity.

6. Test Traction Control Switch

Locate the traction control switch in the vehicle's cabin.
Ensure the switch is functioning correctly by pressing it and observing if the dashboard light responds accordingly.
Replace the switch if it does not operate as expected.

7. Tire Inspection

Check all tires for proper inflation, tread depth, and uneven wear patterns.
Inflate tires to the manufacturer's recommended pressure and replace if necessary.
