Solution

1. Preparation

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

2. Inspect and Clean Wheel Speed Sensors

Remove the wheel and tire assembly to access the wheel speed sensors.
Inspect each sensor for dirt and debris; clean using a soft brush and brake cleaner if necessary.
Reattach the sensor connectors securely.

3. Check and Refill Brake Fluid

Remove the master cylinder cap and check the brake fluid level.
If low, use the recommended brake fluid type (DOT 3 or DOT 4) to refill to the proper level.
Replace the master cylinder cap securely.

4. Repair or Replace Damaged Components

Inspect wiring harnesses for cuts or fraying; repair as necessary using electrical tape or connectors.
If any wheel speed sensors are damaged, replace them with OEM or equivalent parts.
Reinstall any components removed during inspection.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and check if the ABS light turns off.
Conduct a test drive to ensure that the ABS system functions correctly.
