Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the sensor wiring harness connectors carefully.
Clean the sensors with a brake cleaner to remove any debris or dirt.
Reconnect the connectors securely.

3. Check and Replace the Traction Control Switch (if faulty)

Remove the panel covering the traction control switch.
Disconnect the switch connector.
Test the switch with a multimeter for continuity; replace if defective.
Reinstall the switch and panel.

4. Inspect and Replace ABS Module (if necessary)

Locate the ABS module under the hood.
Disconnect the wiring harness and brake lines carefully.
Remove the module using a socket set with the appropriate torque specifications for reinstallation.
Install the new ABS module and reconnect all harnesses and lines.
Bleed the brake system to remove any air trapped in the lines.

5. Final Steps

Reconnect the battery.
Clear any fault codes using the OBD-II scanner.
Test drive the vehicle to ensure the traction control system is functioning correctly.
