Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, brake fluid.
Ensure the vehicle is parked on a level surface and the engine is off. Disconnect the negative battery terminal for safety.

2. Scan and Clear Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Retrieve and note any error codes related to the ABS.
Clear the codes and recheck to see if they return after a brief test drive.

3. Inspect and Repair ABS Components

ABS Wheel Sensors:
- Locate each wheel's ABS sensor, typically mounted near the brake rotor.
- Disconnect the sensor wiring harness and inspect for corrosion or damage.
- Replace any faulty sensors with new units as needed.
Wiring Inspection:
- Check the wiring harness leading to the ABS module for frays or disconnections.
- Repair or replace damaged wiring as necessary.

4. Brake System Check

Brake Fluid:
- Remove the brake fluid reservoir cap and check the fluid level.
- If low, top up with the manufacturer-recommended brake fluid (usually DOT 4).
Brake Components:
- Inspect the brake pads and rotors for wear. Replace any that are worn beyond specifications.
- Check calipers for proper operation and replace if necessary.

5. Reassemble and Test

Reconnect all components and ensure that all connections are secure.
Reconnect the negative battery terminal.
Start the vehicle and check if the ABS light remains off after a test drive.
