Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, vehicle lift or jack stands.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts during repairs.

2. Retrieve and Analyze Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Read and document any error codes related to the traction control system.
Clear the codes and take the vehicle for a test drive to see if the light returns.

3. Inspect Wheel Speed Sensors

Raise the vehicle and remove the front wheels for better access.
Locate the wheel speed sensors on each hub assembly.
Inspect the sensors for dirt, damage, or disconnection.
Clean debris using a soft brush or cloth; reconnect any loose connections.

4. Check Brake Fluid and ABS Module

Inspect the brake fluid reservoir; top off with the manufacturer-recommended brake fluid if low.
Examine the ABS module for leaks or corrosion.
Ensure all electrical connections to the ABS module are secure.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to check for continuity when the switch is pressed.
Replace the switch if it fails the continuity test.

6. Reassemble and Reconnect Battery

Once repairs are completed, reinstall any removed components and wheels.
Reconnect the battery terminal.
Lower the vehicle and ensure all tools are removed from the engine bay.
