Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and turn off the ignition.
Disconnect the battery to prevent any electrical shorts.

2. Check and Replace ABS Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers and inspect it for damage.
If the fuse is blown, replace it with a new one of the same amperage.

3. Inspect and Clean ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensor and the surrounding area using a clean cloth or brush.
If the sensor is damaged or corroded, replace it with a new one.

4. Check Wiring and Connectors

Inspect the wiring harness and connectors leading to the ABS module and sensors.
Look for any signs of wear, fraying, or disconnection.
If damage is found, repair or replace the affected wiring or connectors.

5. Brake Fluid Check

Open the hood and locate the brake master cylinder reservoir.
Check the brake fluid level; it should be between the minimum and maximum marks.
If low, top off with the appropriate brake fluid specified in the owner’s manual.

6. Reconnect Battery and Clear Codes

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any ABS-related error codes.
Check that the ABS light remains off after clearing codes.
