Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, stable surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Inspect and Replace Wheel Speed Sensors

Locate Wheel Speed Sensors: Identify the location of the ABS wheel speed sensors on each wheel.
Remove the Wheel: Use a socket set to remove the lug nuts and take off the wheel.
Disconnect Sensor Connector: Carefully unplug the electrical connector from the sensor.
Remove the Sensor: Remove any bolts or clips securing the sensor and gently pull it out of the hub.
Install New Sensor: Position the new sensor in place, secure it with bolts, and reconnect the electrical connector.
Reinstall Wheel: Place the wheel back on and hand-tighten the lug nuts. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.

3. Check and Replace ABS Fuse

Locate Fuse Box: Open the fuse box under the dashboard or hood.
Identify ABS Fuse: Refer to the fuse diagram to locate the ABS fuse.
Inspect Fuse: Remove the fuse and check for continuity using a multimeter; replace if blown.
Reinstall Fuse: Insert the new fuse back into the correct slot in the fuse box.

4. Brake Fluid Level Inspection

Locate Brake Fluid Reservoir: Find the brake fluid reservoir under the hood.
Check Fluid Level: Ensure the fluid level is between the minimum and maximum marks.
Top Off Fluid: If low, add the manufacturer-recommended brake fluid until the appropriate level is reached.

5. Reconnect Battery

Reconnect the negative battery terminal and ensure it is tight.

6. Test the System

Start the vehicle and check if the ABS light is still illuminated. If the light remains off, perform a test drive to verify brake function.
