Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal.

2. Inspect ABS Fuse

Locate the fuse box and identify the ABS fuse using the diagram.
Remove the fuse using a fuse puller.
Inspect the fuse for continuity; replace if blown.
Reinstall the fuse and reconnect the battery terminal.

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; add brake fluid if low (use DOT 3 or DOT 4 fluid as specified).
Inspect for any visible leaks in the brake lines and around the reservoir.

4. Inspect Wheel Speed Sensors

Jack up the vehicle and secure it on jack stands.
Locate the wheel speed sensors at each wheel hub.
Disconnect the sensor connectors and inspect for dirt or damage.
Clean the sensor and mounting area with a suitable cleaner.
Reconnect the sensors ensuring a secure connection.

5. Check Wiring Harness

Visually inspect the wiring harness leading to the ABS module for any signs of wear or damage.
Use a multimeter to check for continuity in the wires.
Repair or replace any damaged sections of the wiring harness.

6. Reset ABS System

Using the OBD-II scanner, clear the ABS fault codes.
Recheck for codes to confirm the issue has been resolved.
Test the brakes to ensure proper functionality of the ABS.
