Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check ABS Fuse

Locate the fuse box (usually under the dashboard or in the engine bay).
Remove the ABS fuse using a fuse puller or pliers.
Inspect the fuse; replace it if it is blown with a fuse of the same amperage.

3. Inspect and Clean Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensors.
Inspect the sensor for dirt and debris; clean with a soft brush or cloth.
Check the sensor's connector for corrosion; clean with electrical contact cleaner.

4. Repair or Replace Damaged Wiring

Inspect the wiring harness connected to the ABS module and wheel speed sensors.
Look for frayed wires, loose connections, or corrosion.
Repair damaged wiring with electrical tape or replace the section if necessary.

5. Test ABS Module

Reconnect the battery terminal.
Use a multimeter to check the ABS module's voltage and ground connections.
If the module is faulty, follow the manufacturer’s instructions for replacement.
