1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical shorts.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the sensor connectors and visually inspect for corrosion or damage.
Clean any dirt or debris around the sensors and connectors using electrical contact cleaner.
Reconnect the sensors and ensure they are securely in place.

3. Check ABS Module

Locate the ABS module, typically found near the master cylinder.
Inspect wiring and connectors for any signs of wear or damage.
Using a multimeter, check for proper voltage and continuity in the wiring harness.
If necessary, replace any damaged components.

4. Test Traction Control Switch

Identify the traction control switch on the dashboard.
Use a multimeter to check for continuity when the switch is pressed.
If the switch is faulty, remove it from the dashboard and replace it with a new part.

5. Reassemble and Reconnect

Reconnect the battery and ensure all tools and parts are removed from the engine compartment.
Start the vehicle and check if the traction control light remains illuminated.
