Hi,
Have you checked the bulbs condition? Also, have you checked to see if there is power available to the lights at the socket?
Next, the power to the lights comes from the footwell module. The module receives power from a few fuses,
Below, I attached a pic from the reverse lamp wiring schematic. I highlighted fuses to check, they will be in the right-side fuse box. Confirm they are good. In addition, it is important to confirm there is power to and from the fuse.
