Solution

1. Preparation

Gather necessary tools and parts. Disconnect the negative battery terminal.

2. Inspect Wheel Speed Sensors

Tools Required: Multimeter, socket set
Check each wheel speed sensor for proper electrical resistance using a multimeter.
Remove any damaged or dirty sensors, clean them, and reinstall or replace if necessary.

3. Check Traction Control Module

Tools Required: OBD-II scanner
Using the OBD-II scanner, check for DTCs (Diagnostic Trouble Codes) related to the traction control system.
If codes indicate the module is faulty, proceed to replace the traction control module.

4. Inspect Wiring and Connectors

Tools Required: Wire stripper, electrical tape
Visually inspect all wiring and connectors associated with the traction control system for fraying or corrosion.
Repair any damaged wiring as needed and secure connections.

5. Reassemble and Test

Reconnect the negative battery terminal and start the vehicle.
Clear any error codes using the OBD-II scanner.
Perform a test drive to ensure the traction control system operates correctly.
