Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning solution, soft brush
Remove the wheels to access the wheel speed sensors.
Clean the sensors and their mounting surfaces to remove dirt and debris.
Reinstall the wheels and ensure they are properly torqued.

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, top off with manufacturer-recommended brake fluid.
Check for leaks in the brake system that may have caused the fluid loss.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness connected to the wheel speed sensors and ABS module.
Look for frayed wires, corrosion, or loose connections.
Repair or replace any damaged wiring or connectors as needed.

5. Test ABS Module

Reconnect the battery.
Use the OBD-II scanner to run a self-test of the ABS module.
If faults are detected, follow the diagnostic trouble codes (DTC) to determine necessary repairs.
