Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and securely supported with jack stands.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensor area using a clean cloth.
Check the wiring harness for frayed or damaged wires.
Reconnect any loose connectors securely.

3. Replace ABS Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the old fuse with a fuse puller and replace it with a new fuse of the same amperage.

4. Test and Replace Brake Pedal Switch (if necessary)

Locate the brake pedal switch above the brake pedal.
Disconnect the wiring harness and remove the switch from its mounting.
Test the switch with a multimeter to ensure it opens and closes correctly.
Replace the switch if it fails the test.

5. Inspect and Repair ABS Control Module

If necessary, remove the ABS control module from its mounting.
Inspect the module for signs of moisture or corrosion.
Reconnect the module and ensure all electrical connections are secure.
