Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Scan and Analyze Codes

Use the OBD-II scanner to retrieve any diagnostic trouble codes (DTCs).
Note any codes related to the ABS or traction control system for further investigation.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any debris and clean the sensor area.
Check wiring for frays or corrosion.
Use a multimeter to test the resistance of the sensors; replace any faulty sensors.

4. Check ABS Module

Inspect the ABS module connectors for corrosion or loose connections.
If codes indicate a fault with the ABS module, consider replacing it.
Use a scan tool to clear error codes after repairs.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Remove the switch and perform a continuity test with a multimeter.
Replace the switch if it fails the continuity test.

6. Reassemble and Reconnect

Reconnect the battery terminal.
Ensure all components are securely fastened and connected.
Start the vehicle and check if the traction control light is still illuminated.
