Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and cleaning supplies.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean ABS Wheel Speed Sensors

Sub-steps:
1. Locate the ABS wheel speed sensors at each wheel hub.
2. Remove the mounting bolts using a socket set.
3. Carefully detach the sensor from the wheel hub.
4. Clean the sensor and the area around it with brake cleaner.
5. Reinstall the sensor and secure it with the mounting bolts.

3. Check and Replace ABS Relay and Fuses

Sub-steps:
1. Locate the ABS relay and fuse in the fuse box.
2. Remove the relay and test it with a multimeter for continuity.
3. Replace the relay if it is faulty.
4. Inspect the fuse; replace it if it is blown.

4. Inspect and Replace Brake Fluid

Sub-steps:
1. Remove the brake fluid reservoir cap.
2. Check the fluid level; if low, add the recommended brake fluid type (DOT 3 or DOT 4).
3. If the fluid is contaminated, perform a brake fluid flush.
4. Reinstall the cap securely.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any fault codes.
Start the vehicle and check if the ABS light remains off.
