Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface, and engage the parking brake.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace ABS Wheel Speed Sensors

Sub-steps:
- Locate the ABS wheel speed sensors at each wheel hub.
- Remove the bolts securing the sensor (typically a T30 Torx or 10mm socket).
- Carefully pull the sensor from its mount, ensuring not to damage the wiring.
- Inspect the sensor for any cracks or debris; replace if necessary.
- Install the new sensor in reverse order, tightening to the manufacturer's torque specification (usually around 8-10 Nm).
Tools Required: Socket set, torque wrench.

3. Check and Replace ABS Fuses

Sub-steps:
- Locate the fuse box, usually found under the dashboard or in the engine bay.
- Identify the ABS fuse using the diagram on the fuse box cover.
- Remove the fuse and inspect it for continuity. Replace it if it is blown.
- Reinstall the fuse and close the fuse box.
Tools Required: Fuse puller or long-nose pliers.

4. Reconnect Battery and Clear Codes

Sub-steps:
- Reconnect the battery terminals, ensuring they are tight.
- Use the OBD-II scanner to clear any stored ABS fault codes.
- Start the vehicle and check if the ABS light remains off.
Tools Required: OBD-II scanner.
