Solution

1. Preparation

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

2. Retrieve and Address Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and record any ABS-related fault codes.
Clear the codes and observe if they return after a test drive.

3. Inspect and Clean Wheel Speed Sensors

Raise the vehicle using a jack and secure with jack stands.
Locate each wheel speed sensor at the wheel hub.
Disconnect the sensor connector.
Clean the sensor and mounting area with brake cleaner and a soft brush.
Reconnect the sensor and repeat for all wheels.

4. Check ABS Fuse

Locate the fuse box under the dash or in the engine compartment.
Identify the ABS fuse using the fuse diagram.
Remove the fuse and check for continuity using a multimeter.
Replace the fuse if it is blown.

5. Examine Brake Fluid Level

Check the brake fluid reservoir located near the master cylinder.
Ensure the fluid is at the recommended level; if low, top off with the specified brake fluid (DOT 3 or DOT 4).
If the fluid is dirty, consider a brake fluid flush.

6. Test ABS Module and Pump

Reconnect the battery terminal.
Start the vehicle and monitor the ABS light.
Conduct a test drive to check the ABS operation.
If the light remains on, further diagnostics of the ABS module may be needed or consult a professional technician.
