Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the ignition is off.
Gather necessary tools and parts.

2. Scan and Clear 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 note any ABS-related fault codes.
Clear the fault codes and check if the ABS light turns off.

3. Inspect ABS Components

Wheel Speed Sensors:
- Lift the vehicle and remove the wheel.
- Locate the wheel speed sensor and inspect it for physical damage or dirt buildup.
- Clean the sensor with a soft cloth if necessary.
- Reconnect any loose connectors and ensure proper seating.
ABS Fuse:
- Locate the fuse box (consult the owner’s manual for location).
- Remove the ABS fuse and check for continuity using a multimeter.
- Replace with a new fuse if the old one is blown.

4. Check Brake Fluid and System

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level and top off with the appropriate brake fluid type (usually DOT 4).
Inspect brake lines for leaks; repair or replace as necessary.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Start the engine and check if the ABS light has turned off.
Conduct a test drive to ensure the ABS system is functioning correctly.
