Solution

1. Preparation

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

2. Inspect and Replace ABS Fuse

Locate the fuse box (refer to the owner's manual for the exact location).
Remove the ABS fuse using a fuse puller or pliers.
Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage.

3. Inspect and Clean Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector of each sensor.
Clean the sensor and the mounting area of any dirt or debris using a clean rag.
Reconnect the sensors ensuring the connectors are secure.

4. Check and Replace Damaged Components

If any wiring or connectors are damaged during inspection, replace them as necessary.
If any wheel speed sensor is found to be faulty after resistance testing, remove the sensor by unscrewing it from the hub and install a new one.

5. Refill Brake Fluid

If the brake fluid is low, remove the brake fluid reservoir cap.
Use the manufacturer's recommended brake fluid type to refill the reservoir to the proper level.

6. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Start the vehicle and check if the ABS light is still illuminated.
Take the vehicle for a short test drive to ensure normal braking function and verify the ABS light is off.
