Anyone have any idea what would cause centre reading and step lights and tail gate open light to not work?

Front and rear dome light working, but those in the centre and the tail gate open light are not working.

Fuses maybe? I doubt it is bulbs.

Have you checked fuses? (Behind coin cubby in front of driver’s right knee)

Not the fuses. I went about it the wrong way round.

Turns out five Interior lights are missing globes altogether. Wondering if they were removed for a reason.

Off to buy them now.

Probably had expensive led items removed for sale or during storage/ transport.

Maybe P/O put LEDs in and stuffed up the BCM, and then removed them altogether to hide the fault ? New bulbs will give you a clue.

Body control module

Canbus uses various models to control various parts of car’s electrical systems to keep wire numbers, length, compilation and costs down as ever more features and interlinking becomes necessary. Data connection between the modules carries command information on one wire rather than having one circuit for each function.

Step light and tgate open light take control from rear cab idpm
Cabin light is controlled by roof c/u
You may want to look in that direction if you dont solve the problem
