Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure electrical safety during repairs.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris from the sensor area using a clean cloth and brake cleaner.
Ensure the sensor connectors are secure and free of corrosion.
Reconnect the sensors.

3. Check ABS Module and Wiring

Inspect the ABS module for any visible damage or leaks.
Use a multimeter to check for continuity in the wiring harness connected to the ABS module.
Repair or replace any damaged wiring as needed.

4. Tire Inspection

Measure the tire pressure using a tire gauge and adjust as necessary to meet manufacturer specifications.
Inspect the tire tread for uneven wear; replace tires if necessary.

5. Reconnect Battery

Reconnect the negative battery terminal.
Clear any error codes using the OBD-II scanner.
