Solution

1. Preparation

Ensure the vehicle is on a flat surface and securely parked.
Disconnect the battery to prevent electrical shorts.
Gather tools and components needed for the repair.

2. Inspect and Replace the ABS Fuse

Locate the fuse box; refer to the owner's manual for the ABS fuse location.
Use a fuse puller or pliers to remove the ABS fuse.
Check the fuse for continuity. Replace with a fuse of the same amperage if necessary.

3. Inspect Wiring and Connectors

Visually inspect the ABS wiring harness and connectors for signs of wear, fraying, or corrosion.
If damaged, repair or replace the wiring as necessary.

4. Test Wheel Speed Sensors

Raise the vehicle on jack stands and remove the wheels to access the wheel speed sensors.
Disconnect each sensor and use a multimeter to measure the resistance; typical values should fall within manufacturer specifications (refer to service manual).
Replace any faulty wheel speed sensors.

5. Brake Fluid Inspection

Check the brake fluid level in the master cylinder reservoir.
If low, top off with the recommended brake fluid type (DOT 3 or DOT 4, as specified in the manual).
If fluid is contaminated, perform a brake fluid flush.

6. ABS Module Replacement (if necessary)

If all previous tests indicate the ABS module is faulty, remove the module by disconnecting the electrical connectors and mounting bolts.
Install the new ABS module, ensuring all connections are secure.
Reconnect the battery and clear any error codes using the OBD-II scanner.
