Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the vehicle to cool down before proceeding with any inspection.

2. Inspect Wheel Speed Sensors

Remove the wheels to access the wheel speed sensors.
Clean the sensors with a soft cloth and inspect the wiring harness for fraying or disconnection.
Reconnect or replace any damaged connectors or wiring.

3. Check Battery and Electrical Connections

Inspect the battery terminals and clean them if corroded.
Use a multimeter to check the battery voltage; it should be between 12.4V and 12.7V.
Tighten any loose electrical connections related to the traction control system.

4. Test Brake Pedal Switch

Locate the brake pedal switch, typically found near the top of the brake pedal assembly.
Disconnect the switch and test it with a multimeter to ensure it opens and closes correctly when the pedal is pressed.

5. Clear Error Codes and Test

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored error codes.
Test drive the vehicle to check if the traction control system is functioning properly.
