Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues.

2. Inspect and Clean Wheel Speed Sensors

Remove the wheel for access to the wheel speed sensor.
Clean the sensor and surrounding area with brake cleaner to remove dirt and debris.
Inspect the wiring harness for frays or breaks.
Reinstall the wheel and repeat for all four corners.

3. Check Brake Fluid and Brake Lines

Inspect the brake fluid reservoir; refill if low using the manufacturer-recommended brake fluid.
Examine brake lines for any visible leaks or damage. Replace any damaged lines.
If leaks are present, follow appropriate replacement procedures.

4. Test and Replace the ABS Control Module (if necessary)

Use an OBD-II scanner to check the ABS control module status.
If the module is faulty, remove it by disconnecting the wiring harness and unbolting it.
Install a new ABS control module, ensuring connections are secure.
Reconnect the battery.

5. Calibrate Steering Angle Sensor

Use a scan tool to access the steering angle sensor calibration feature.
Follow the on-screen prompts to complete the calibration.
Ensure that the steering wheel is centered during the calibration process.
