Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake fluid, cleaning supplies.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts while working on the ABS system.

2. Inspect and Clean ABS Sensors

Remove the wheel covers or wheels as necessary to access the ABS sensors.
Clean the sensors and the mounting area with a suitable cleaner to remove dirt and debris.
Reconnect any loose or corroded connectors and secure them properly.

3. Replace Faulty ABS Sensor

If a sensor is found to be faulty, remove the old sensor by unscrewing it from its bracket.
Install the new ABS sensor by reversing the removal process, ensuring it is securely fastened.
Reconnect the wiring harness to the new sensor.

4. Check Brake Fluid and Add if Necessary

Locate the brake fluid reservoir and check the fluid level.
If low, add the specified brake fluid type (consult the owner's manual for the correct type).
Ensure there are no leaks in the brake lines or around the reservoir.

5. Reconnect Battery and Clear Codes

Reconnect the battery once all repairs are complete.
Use the OBD-II scanner to clear any error codes related to the ABS.
Check to ensure that the ABS light is no longer illuminated.
