Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub assembly.
Use a socket set to remove any securing bolts.
Disconnect the electrical connector from the sensor.
Clean the sensor and its mounting area with brake cleaner to remove dirt or debris.
Reinstall the sensor and secure it with the bolts.

3. Check Traction Control Switch

Locate the traction control switch, usually found near the gear shifter or dashboard.
Use a multimeter to test the switch for continuity.
If the switch is faulty, remove it and replace it with a new one.
Reconnect the switch’s electrical connector.

4. Verify Brake System Functionality

Inspect the brake fluid level and add fluid if necessary.
Check for any leaks in the brake lines or around the ABS module.
Use a diagnostic tool to read ABS fault codes and clear any errors.

5. Reconnect Battery

Reconnect the negative terminal of the battery.
Ensure all connections are tight and secure.

6. Test Drive

Start the vehicle and take it for a test drive to ensure that the traction control light does not re-illuminate.
Monitor vehicle performance and responsiveness during acceleration and braking.
