Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, cleaning materials (cloth, mild cleaner).
Ensure the vehicle is parked on a level surface and in a safe area.
Disconnect the battery before starting any electrical work if necessary.

2. Inspect and Clean Sensors

Sub-steps:
1. Locate the parking sensors on the front and rear bumpers.
2. Clean each sensor using a soft cloth and mild cleaner to remove dirt or debris.
3. Inspect sensors for any signs of damage or misalignment.

Sub-steps:
1. Reconnect the battery if it was disconnected.
2. Start the engine and engage the vehicle in reverse.
3. Use the OBD-II scanner to clear any existing error codes.
4. Observe the response of the sensors while moving closer to an object. The beeping should change with proximity.
Note: If sensors continue to beep without obstruction, further diagnosis may be needed.

4. Reconfigure Parking Assistance Settings

Sub-steps:
1. Access the vehicle’s on-board computer system via the infotainment display.
2. Navigate to parking assistance settings and ensure they are set to the desired sensitivity level.
