Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat, stable surface and securely lifted if needed.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove the sensor mounting bolts using a socket set.
Carefully disconnect the electrical connector for each sensor.
Inspect the sensor for dirt or damage; clean or replace as necessary.
Install the new or cleaned sensor, reconnect the electrical connector, and secure with the mounting bolts.

3. Check and Replace ABS Fuse

Locate the fuse box and identify the ABS fuse using the diagram provided in the owner's manual.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace with a new fuse of the same amperage if blown.
Reinstall the fuse and ensure it is seated properly.

4. Inspect ABS Pump and Module

Locate the ABS pump and module assembly, typically found near the master cylinder.
Inspect for any visible leaks or damage to the assembly.
If damaged, disconnect the battery and remove the hydraulic lines using a wrench, then remove the mounting bolts.
Replace with a new ABS pump/module assembly, ensuring to torque the mounting bolts to the manufacturer's specifications.
