Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid.
Ensure the vehicle is parked on a level surface, and set the parking brake.
Disconnect the battery to prevent any electrical shorts during the repair.

2. Inspect and Replace ABS Fuse

Locate the fuse box (consult the owner's manual for exact location).
Use a fuse puller or pliers to remove the ABS fuse.
Inspect the fuse for continuity using a multimeter; replace it if blown.
Reinstall the fuse and reconnect the battery.

3. Check Brake Fluid Level

Open the hood and locate the brake master cylinder reservoir.
If low, top off with the manufacturer's recommended brake fluid (DOT 3 or DOT 4).
Inspect for any leaks in the brake lines or around the master cylinder.

4. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensor.
Inspect the sensor and wiring harness for damage or disconnection.
Clean any debris from the sensor and check for proper alignment.
Reinstall the wheel and lower the vehicle.

5. Test ABS Control Module

Using the OBD-II scanner, check for any active trouble codes related to the ABS system.
If codes are present, follow the manufacturer’s troubleshooting guidelines to address specific issues.
If no codes are found and the problem persists, consider replacing the ABS control module.
