Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Tools Required: OBD-II scanner, socket set, multimeter, brake fluid, wire brush, dielectric grease.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve and document any ABS-related error codes for further analysis.

3. Inspect and Replace Wheel Speed Sensors (if necessary)

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheels to access the wheel speed sensors.
Disconnect the sensor wiring harness and remove the sensor using a socket.
Inspect the sensor for dirt or damage; clean with a wire brush or replace if damaged.
Reinstall the sensor, reconnect the wiring, and repeat for all wheels.

4. Check and Replace ABS Fuse

Locate the fuse box and identify the ABS fuse using the diagram on the cover.
Remove the fuse and inspect it for continuity; replace if blown.
Reinstall the fuse and ensure it is seated correctly.

5. Inspect ABS Module and Wiring

Visually inspect the ABS module located near the brake master cylinder for any signs of corrosion or loose connections.
Use a multimeter to test for voltage at the ABS module; ensure proper connections.
Apply dielectric grease to connectors to prevent corrosion.

6. Test Brake System

Inspect brake lines and calipers for leaks or damage.
Top off the brake fluid if needed and bleed the brake system to remove air.
Start the vehicle and verify that the ABS light is off after resolving the issue.
