Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and the parking brake engaged.
Disconnect the negative battery terminal to avoid 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.
If necessary, unbolt the sensor and inspect for physical damage. Replace if damaged.

3. Check and Replace Brake Fluid

Remove the master cylinder cap and check the brake fluid level.
If low, top off with the recommended brake fluid (DOT 3 or DOT 4, as specified in the owner’s manual).
If the fluid is contaminated (dark or dirty), perform a brake fluid flush.

4. Repair or Replace ABS Sensor Wiring

Visually inspect the ABS sensor wiring for frays, breaks, or corrosion.
Repair any damaged wiring with appropriate electrical tape or heat-shrink tubing.
Replace any severely damaged wires or connectors.

5. Reconnect Battery and Reset ABS System

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored ABS trouble codes.
Start the vehicle and allow it to run for a few minutes to check if the ABS light remains off.
