Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove the sensor mounting bolts using a socket set.
Carefully detach the sensors from their mounts.
Clean the sensor tips with brake cleaner and a soft cloth.
Reinstall the sensors and tighten the bolts to the manufacturer’s specified torque.

3. Check and Replace ABS Fuse

Locate the ABS fuse in the fuse box (consult the owner's manual for the exact location).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for any damage; replace it if it is blown with the same amperage rating.

4. Inspect ABS Wiring Harness

Locate the wiring harness connected to the ABS module.
Visually inspect the wiring for signs of wear, fraying, or corrosion.
Repair any damaged wires using appropriate electrical connectors or tape.

5. Brake Fluid Inspection

Open the brake fluid reservoir cap and check the fluid level.
If low, top off with the manufacturer's recommended brake fluid type.
Inspect for any visible leaks in the brake lines or connections.

6. Reconnect Battery and Test System

Reconnect the battery terminals securely.
Turn on the vehicle and check if the ABS light remains illuminated.
Take the vehicle for a test drive to ensure the ABS functions correctly.
