Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative terminal of the battery to prevent electrical shock.
Allow the vehicle to cool down if it has been recently driven.

2. Inspect and Test Traction Control Switch

Remove the trim panel surrounding the traction control switch using a trim tool.
Disconnect the electrical connector from the switch.
Use a multimeter to test the switch for continuity. If faulty, replace with a new switch.

3. Check and Clean Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensors.
Clean any dirt or debris from the sensors and their connectors.
Inspect the wiring for any damage. If damaged, replace the sensor.

4. Inspect ABS Module and Wiring

Locate the ABS module under the hood or near the brake assembly.
Check the module connections for corrosion or loose wires.
If the module is faulty, replace it following manufacturer specifications.

5. Reconnect Battery and Perform System Reset

Reconnect the negative terminal of the battery.
Start the vehicle and check for any warning lights.
If the issue persists, use the OBD-II scanner to clear any stored fault codes.
