Solution
1. Preparation
  • Gather tools and components necessary for repair.
  • Ensure the vehicle is parked on a flat surface and the ignition is off.
  • Disconnect the battery to prevent electrical shock.
2. Clean Sensors
  • Locate the parking assist sensors, typically mounted on the rear bumper.
  • Use a soft cloth and mild detergent to clean each sensor and remove dirt or debris.
  • Rinse with clean water and dry thoroughly before reconnecting.
3. Inspect Wiring and Connections
  • Remove the rear bumper if necessary for better access to the wiring harness.
  • Visually inspect the wiring for fraying, cracking, or corrosion.
  • Use a multimeter to test the continuity of the wiring connections to the sensors and control module.
  • Repair or replace any damaged wiring or connectors.
4. Test and Replace Faulty Components
  • Reconnect the battery and turn on the ignition.
  • Use the OBD-II scanner to check for error codes again.
  • If codes indicate faulty sensors, replace them one at a time, ensuring to torque the mounting screws to the manufacturer's specifications (typically around 5-7 ft-lbs).
  • If the control module is defective, follow the service manual for replacement procedures, ensuring to properly program the new module if required.
