Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety while working with electrical components.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris that may be obstructing the sensors using a clean cloth.
Check the wiring connected to the sensors for any signs of wear or damage.
Reconnect any loose connections and secure the wiring.

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Verify that the brake fluid level is within the recommended range.
If low, refill with the manufacturer-recommended brake fluid type.

4. Test and Repair ABS Module

Reconnect the battery terminal.
Use the OBD-II scanner to check for any ABS fault codes.
If codes are present, follow the manufacturer's service manual for specific diagnostics and repair procedures for the ABS module.

5. Final Assembly

Reassemble any components that were removed during the inspection.
Ensure all connections are secure and that there are no loose parts.
Lower the vehicle if it was raised for inspection.
