Remove the rear bumper if necessary to access the wiring harness connected to the parking sensors.
Inspect the wiring for any signs of damage or corrosion.
Reconnect any loose or corroded connections.

4. Test and Replace Sensors (if needed)

Reconnect the battery and test the reverse function.
If beeping persists, use a multimeter to test each sensor for proper voltage and operation.
