Reverse Lights not working

Trying to figure out an issue with my reverse lights not coming on. Replaced bulbs, checked fuses…

From what I have been looking into it seems to potentially be the back-up light switch on the transmission or the neutral safety switch. Curious if anyone has had this issue before, it’s a 2011.

Did you check the relay?




Did you test and see if there is power sent to and from the park/neutral switch when in reverse with your DMM?

Pin 1 lilac/ w red stripe wire, should be hot when in reverse with the ignition on.
Pin 2 green wire to the switch from the battery, should be hot with the ignition on.
