Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Scan for Codes

Reconnect the battery and use an OBD-II scanner to read codes.
Document any fault codes related to the traction control system.

3. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it on jack stands.
Locate each wheel speed sensor and inspect wiring for wear or disconnection.
Clean any debris from the sensors and connectors.

4. Check ABS Module

Inspect the ABS module located in the engine bay for any visible damage.
If fault codes indicate ABS issues, consider replacing the ABS module.

5. Inspect Tires

Check tire tread depth using a tread depth gauge.
Ensure all tires are inflated to the manufacturer's recommended pressure.
Replace any worn or damaged tires.

6. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to test for continuity when the switch is toggled.
Replace the switch if it fails the continuity test.
