Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Fuse Inspection

Locate the fuse box and identify the ABS fuse.
Remove the fuse and check for continuity using a multimeter.
Replace any blown fuses with a fuse of the same amperage.

3. Sensor Inspection

Raise the vehicle and secure it with jack stands.
Remove the wheels to access the ABS wheel speed sensors.
Clean any dirt or debris from the sensors and the tone ring.
Inspect the sensors for physical damage and ensure they are securely connected.

4. Wiring Check

Visually inspect the wiring harness leading to the ABS module for any signs of wear, fraying, or corrosion.
Use a multimeter to test for continuity in the wiring.
Repair or replace damaged wiring as necessary.

5. ABS Module Testing

Reconnect the negative battery terminal.
Use an OBD-II scanner to clear any stored error codes.
If the ABS light remains on, perform a functional test of the ABS module with a diagnostic tool to verify operation.

6. Brake Fluid Check

Open the master cylinder reservoir cap and check the brake fluid level.
If low, top up with the manufacturer-recommended brake fluid (e.g., DOT 3 or DOT 4).
If fluid is dirty, consider a brake fluid flush.
