Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the battery to prevent electrical shorts during inspection.

2. Inspect Wheel Speed Sensors

Remove the wheel corresponding to the sensor that triggered the light.
Locate the wheel speed sensors on the hub assembly.
Clean the sensors and their connectors using electrical contact cleaner.
Reconnect the sensors and reinstall the wheel.

3. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
If the fluid is low, top it off with the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Inspect the brake lines and master cylinder for leaks.

4. Examine Traction Control Module

Access the traction control module, typically located near the ABS unit.
Disconnect the electrical connector and inspect for corrosion or damage.
If corrosion is found, clean the connector with electrical contact cleaner.
Reconnect the module and ensure it is securely mounted.

5. Test Traction Control Switch

Turn on the ignition without starting the engine.
Check the functionality of the traction control switch; the light should turn off when pressed.
If the switch is faulty, replace it following the manufacturer's specifications.
