Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Tools Required: OBD-II scanner, socket set, multimeter, brake cleaner, torque wrench.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Address Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and note any error codes related to the traction control system.
Clear the codes and test drive the vehicle to see if the light reappears.

3. Inspect Wheel Speed Sensors

Raise the vehicle and secure it on jack stands.
Locate the wheel speed sensors at each wheel hub.
Inspect the wiring and connectors for damage or corrosion.
Clean the sensor area with brake cleaner to remove dirt and debris.

4. Check Brake Fluid Level

Locate the brake fluid reservoir.
Inspect the fluid level; if low, fill with the appropriate brake fluid (DOT 3 or DOT 4).
Check for leaks in brake lines and fittings; repair as necessary.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to test the switch for continuity.
If the switch is faulty, replace it with a new one.

6. Verify ABS Module and Wiring

Inspect the ABS module for visible damage or corrosion.
Check wiring harnesses for any signs of fraying or disconnection.
Repair or replace damaged components as necessary.
