Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery before working on electrical systems.

2. Scan for Error Codes

Use an OBD-II scanner to retrieve any trouble codes.
Document any codes related to the traction control system or ABS.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean any debris or dirt from the sensors and connectors.
Check for continuity in the wiring using a multimeter.
Replace any damaged sensors.

4. Examine ABS Module

Inspect the ABS module for any visible damage or corrosion.
Check the wiring harness connected to the ABS module for frays or disconnections.
If needed, replace the ABS module.

5. Tire Inspection

Check all four tires for tread depth and even wear.
Ensure all tires are inflated to the manufacturer’s recommended pressure.
Replace any tires that are worn unevenly or below the minimum tread depth.

6. Brake System Check

Inspect brake pads and rotors for wear.
Look for any leaks in brake lines.
If necessary, replace worn brake components.
