Solution

1. Preparation

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

2. Inspect and Clean ABS Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any debris or dirt around the sensor using a clean cloth or compressed air.
Inspect the sensor for cracks or damage; replace if necessary.

3. Check and Repair Wiring

Visually inspect the wiring harness connected to the ABS sensors for fraying or breaks.
If damaged, repair or replace the wiring as needed using appropriate electrical tape or connectors.

4. Brake Fluid Check

Remove the brake fluid reservoir cap and check the fluid level.
If low, top off with the recommended brake fluid type (usually DOT 4).
Inspect for leaks at brake lines and calipers; repair any found leaks.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal after completing repairs.
Use the OBD-II scanner to clear any ABS fault codes from the system.
