Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to prevent any electrical shorts during the repair.

2. Inspect and Replace ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub assembly.
Remove the wheel using a socket set to access the hub assembly.
Disconnect the sensor wiring harness carefully to avoid damage.
Remove the sensor from the hub using the appropriate socket or wrench.
Install the new sensor by reversing the removal steps, ensuring it is seated properly.
Reconnect the wiring harness and replace the wheel.

3. Check and Top Off Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level and top off with the manufacturer's recommended brake fluid type if low.
Replace the reservoir cap securely.

4. Replace Blown Fuses (if necessary)

Locate the fuse box (refer to the owner’s manual for exact location).
Check the ABS fuse for continuity using a multimeter.
Replace any blown fuses with new ones of the same amperage.
