If you have the lights set up to come on when you unlock the doors with the fob, the backup lights are part of that feature. Use the fob from the back of the car to unlock the doors and look at the lights.

I pulled my DRL fuse and get B502, B507 and B2482. Back up lights still work in reverse.

No. It is fault in the control side of the circuit.

Conditions for Setting the DTC:

The BCM detects a low voltage level (an open or a short to ground) in the backup lamp relay control circuit.
The BCM can only test for this condition with the backup lamp relay de-energized.
The condition must be present for 2 seconds.

This thread probably belongs over in Tech.
