Hi all,

My technician just told me that the reason I have no electrical power at the fuel door actuator is because “the module” is bad. He tells me that it’s a multi-function module and (a new or used one) would need to be programmed by a Hyundai dealer. I cant find any info online on this module. Honestly, I wonder if it’s a relay.

Anyway, has anyone heard of this unique module or where it’s located?

I think your "technician" is talking B/S. No power to the actuator is more likely to be a faulty switch or broken wire. I doubt there would be any module involved on a 2006 model, which is probably why you can't find any info about it online.

Well, I’ve continued to research this after my post, and I talked directly to the tech. As it turns out, these cars have a ‘Body Control Module’ that is a central kind of relay for everything electrical on the body of the car... like sunroof, mirrors, windows, door locks and the fuel door actuator. I actually think this could be the problem. I’ve bought a used one (new are over $300) and I’m going to have a Hyundai dealer “flash” it to my exact car. I’m really hoping this works because opening the trunk to pull on the chord is getting old.

Thanks for your reply.

Yeah, me too. But having been an AUTOSPARK in a Hyundai dealership I feel pretty confident it will not. Sorry.

I had a wee job on today that required my diagnostic laptop. So while I had it fired up I grabbed the NF Sonata fuel door release circuit diagram for you. I don't see any connection to the body control module though. The BCM is part of the trunk release but has no part in the fuel door circuit, according to the diagram.

Which part needs to be replaced? My girlfriend's car has this issue. Thanks.
