Solution

1. Preparation

Gather tools and parts required for the repair.
Safety: Ensure the vehicle is parked on a level surface and the engine is off. Disconnect the battery before starting any electrical work.

2. Retrieve and Analyze Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine.
Record any ABS-related fault codes for reference.

3. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensor.
Disconnect the sensor harness and visually inspect the sensor for any cracks or debris.
Clean the sensor and surrounding area with brake cleaner if dirty.

4. Check ABS Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the fuse and check for continuity using a multimeter. Replace if blown.

5. Verify Brake Fluid and System Integrity

Check the brake fluid level in the master cylinder; top off with manufacturer-recommended fluid if low.
Inspect brake lines for leaks or damage, and check for any signs of air in the brake system.

6. Clear Error Codes

After addressing any identified issues, reconnect the OBD-II scanner.
Clear the error codes to reset the ABS system.
