4304 back up alarm goes off while setting

Has anyone had an issue where while parked the back up alarm goes off and reverse lights come on? they go back off after a while.

I have a 2005 4304 Newmar Mountain Aire with a 400 Cummins and a 6 speed Allison transmission 3000 series

Thank You!

The back-up lights power the back-up alarm. Locate the back-up light plug and you will probably find the source of the alarm sounding. My first guess is the cannon plug on the transmission.

He’s correct the alarm is triggered by the lights. When you hear the alarm, if you turn on the ignition, is the touchpad light up for reverse or still in neutral.

If your coach is equipped with a PDM, check that, it may be faulty. I don't know when they started using PDMs in coaches.
