Solution

1. Preparation

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

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris around the sensors using a clean cloth or compressed air.
Check sensor wiring for damage; repair or replace as needed.

3. Check ABS Fuse

Locate the ABS fuse in the fuse box (refer to owner's manual for location).
Use a multimeter to test the fuse for continuity; replace if faulty.
Reinstall the fuse and ensure it is seated properly.

4. Inspect ABS Harness and Connectors

Visually inspect the ABS wiring harness for any frayed wires or loose connections.
Clean connectors with electrical contact cleaner if corrosion is observed.
Ensure all connections are secure before reassembling.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use an OBD-II scanner to clear any existing ABS fault codes from the system.
Start the vehicle and observe if the ABS warning light remains illuminated.
