Solution

1. Preparation

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

2. Replace ABS Fuse

Locate the fuse box and identify the ABS fuse using the diagram on the fuse cover.
Remove the blown fuse using a fuse puller or pliers.
Replace it with a new fuse of the same amperage.
Reconnect the battery.

3. Inspect and Clean Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheels to access the wheel speed sensors.
Disconnect the sensor connectors and inspect for damage or corrosion.
Clean the sensor surface and the mounting area with brake cleaner.
Reconnect the sensors and reinstall the wheels.

4. Repair or Replace ABS Module

If error codes indicate an ABS module failure, remove the module by unbolting it from its mounting.
Disconnect all wiring harnesses attached to the module.
Install the new or repaired ABS module by reversing the removal process.
Ensure that all connectors are firmly attached and bolts are tightened to the manufacturer’s torque specifications.

5. Final Reassembly and Testing

Reinstall any components removed during the process.
Reconnect the battery and clear any error codes using the OBD-II scanner.
Start the vehicle and check for the ABS warning light. Perform a brief test drive to ensure proper functioning of the ABS system.
