Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely supported with jack stands.
Disconnect the negative battery cable to prevent electrical shorts.

2. Check and Replace ABS Wheel Speed Sensors

Remove the wheel and tire assembly to access the wheel speed sensor.
Disconnect the sensor's electrical connector.
Remove the sensor from its mounting location (usually secured with a bolt).
Clean the mounting area and inspect the sensor for damage.
If damaged, install a new ABS wheel speed sensor, ensuring it is properly seated and secured.
Reconnect the electrical connector.

3. Inspect and Refill Brake Fluid

Locate the brake master cylinder reservoir.
Remove the cap and check the brake fluid level; top off with manufacturer-recommended fluid if low.
Inspect for any leaks around the master cylinder and brake lines.

4. Clear Error Codes

Reconnect the negative battery cable.
Use the OBD-II scanner to clear any stored ABS error codes.
Start the vehicle and observe if the ABS light remains illuminated.

5. Test Drive and Recheck

Conduct a test drive, performing several hard stops to test the ABS operation.
Monitor the ABS light for re-illumination during the drive.
