Hi,
What I recommend is this: We need to know what diagnostic trouble codes are stored. In this case, the can-bus needs to be scanned.
CAN stands for controller area network. Basically, the different modules are tied together via a few wires. This type of scan will retrieve codes regardless of the module storing them. This is where we need to start. Otherwise, it will become a guessing game.
Here is a link showing how it's done:

Let me know if that is something you can do or have done. If you can, let me know what codes are stored.
Let me know.
Take care,
joe
