Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, jack and jack stands.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Addressing Error Codes

Use the OBD-II scanner to retrieve and note any error codes.
Clear the error codes from the system and take the vehicle for a test drive to see if they reoccur.

3. Inspect and Replace Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors at each wheel hub.
Disconnect the wiring harness from the sensors.
Remove the bolts securing the sensors and gently pull them out.
Install new wheel speed sensors by reversing the removal process and ensuring secure connections.

4. Check and Replace ABS Module (if necessary)

Locate the ABS module, usually mounted near the brake master cylinder.
Disconnect the electrical connector and brake lines (use a brake line wrench).
Remove the mounting bolts securing the ABS module.
Install the new ABS module and reconnect the brake lines and electrical connectors.
Bleed the brake system to remove any air introduced during the process.

5. Final Assembly and Testing

Recheck all connections and ensure everything is secured.
Lower the vehicle and test drive to verify whether the traction control system is functioning correctly.
