Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, cleaning supplies, torque wrench
Disconnect the battery to prevent electrical shorts.
Allow the vehicle to cool if it has been running.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove the sensor mounting bolts using the socket set.
Carefully pull the sensors out of their mounting points.
Clean the sensors and their mounting areas using a soft cloth or brake cleaner.
Reinstall the sensors and secure them with the mounting bolts, tightening to the manufacturer’s specified torque.

3. Check Wiring and Connectors

Visually inspect the wiring harness connected to the ABS module and wheel speed sensors for any signs of wear or damage.
Use a multimeter to check for continuity in the wires and ensure there are no breaks.
Repair or replace any damaged wiring or connectors as necessary.

4. Verify Brake Fluid Level

Locate the brake fluid reservoir and check the fluid level.
If low, top off with the manufacturer-recommended brake fluid type.
Recheck for any visible leaks around the brake lines and calipers.

5. Reset the System

After completing all inspections and repairs, reconnect the battery.
Use the OBD-II scanner to clear any error codes stored in the system.
Perform a system reset by following the manufacturer’s procedure, if applicable.
