Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the battery to prevent electrical shorts or shocks.

2. Scan and Clear Error Codes

Connect the OBD-II scanner to the diagnostic port under the dashboard.
Retrieve any diagnostic trouble codes (DTCs) related to the traction control system.
Clear the codes and test drive the vehicle to see if the light returns.

3. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any debris or dirt around the sensors to ensure accurate readings.
If damaged, replace the faulty wheel speed sensor(s) with new ones.

4. Check and Top Off Brake Fluid

Locate the brake fluid reservoir and check the fluid level.
If low, top off with the manufacturer-recommended brake fluid.
Inspect for any visible leaks in brake lines or components.

5. Inspect and Replace Fuse

Locate the fuse box and identify the traction control fuse.
Remove the fuse and inspect it for continuity; replace with the correct amp fuse if blown.

6. Test Throttle Position Sensor (TPS)

Locate the TPS on the throttle body.
Use a multimeter to check the resistance values according to specifications.
If readings are outside normal range, replace the TPS.

7. Test Traction Control Switch

Confirm the switch is functioning by pressing it and observing any change in the dashboard lights.
If defective, replace the traction control switch.
