Solution

1. Preparation

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

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris around the sensors using a clean cloth.
Check the sensor mounting bolts and tighten them to the manufacturer’s specifications (usually around 10-15 ft-lbs).
Reconnect any disconnected wiring harnesses.

3. Check and Replace Faulty Components

If error codes indicate a specific faulty sensor, remove the defective sensor:
- Use a socket set to remove the mounting bolts.
- Disconnect the wiring harness.
Install the new sensor:
- Connect the wiring harness.
- Secure the sensor with the mounting bolts, ensuring they are torqued to manufacturer specifications.

4. Reset the ABS Module

Reconnect the battery.
Use the OBD-II scanner to clear any error codes from the ABS module.
Perform a self-test of the ABS system using the scanner to ensure no new codes are generated.

5. Test Drive the Vehicle

Take the vehicle for a test drive to ensure the traction control light does not reappear.
Monitor the vehicle's handling and performance during the drive.
