Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any debris or dirt from the sensor area using a clean cloth or compressed air.
Reconnect any loose wiring or connectors associated with the sensors.

3. Check and Replace the Traction Control Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use a fuse puller to remove the traction control fuse.
Inspect the fuse for continuity; replace it if blown with a new fuse of the same amperage.

4. Test and Replace the Brake Pedal Switch (if necessary)

Locate the brake pedal switch, usually mounted on the brake pedal assembly.
Disconnect the electrical connector from the switch.
Use a multimeter to test the switch for proper operation; replace if defective.

5. Reconnect Battery and Clear Error Codes

Reconnect the negative battery terminal securely.
Use the OBD-II scanner to clear any stored error codes from the system.
Perform a reset of the traction control system.
