Solution

1. Preparation

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

2. Inspect and Replace Wheel Speed Sensors

Sub-steps:
- Locate the wheel speed sensors at each wheel hub; remove the wheel to access them if needed.
- Use a socket set to unbolt the sensor from the hub.
- Disconnect the electrical connector from the sensor.
- Inspect the sensor for dirt or damage; clean or replace if necessary.
- Install the new or cleaned sensor, ensuring the connector is securely attached.
- Reinstall the wheel and torque the lug nuts to the manufacturer's specification.

3. Check and Replace Traction Control Switch

Sub-steps:
- Locate the traction control switch on the dashboard.
- Remove the panel covering the switch if applicable.
- Disconnect the electrical connector from the switch.
- Use a multimeter to test the switch for continuity; replace if defective.
- Reconnect the new switch or the original if operational.

4. Inspect ABS Components

Sub-steps:
- Locate the ABS module and inspect for any loose or damaged wiring.
- Check the ABS sensors for proper connection and function.
- If necessary, replace any damaged ABS components.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals and ensure they are tight.
Use the OBD-II scanner to clear any stored codes related to the traction control system.
Start the vehicle and check if the traction control light is still illuminated.
