Instrument Cluster - immobilizer and coding questions
I know that the following modules are all tied into the immobilizer system of the C7:
ASDM - Air Bag System Diagnostic Module
BCM - Body Control Module
EBCM - Electronic Brake Control Module
ECM - Engine Control Module
HVAC - Heating Ventilation and Air Conditioning Module
IPC - Instrument Panel Control Module
SCLCM - Steering Column Lock Control Module
I also read that replacing one of these modules for throuble shooting (or any other reason) with a used module from another C7 might block the immobilizer.
Anybody here switched between different instrument clusters (IPC) and managed to block the immo due to this after trying to start the engine?
If so how can the immo be unblocked if another instrument cluster was installed for a short time but the original one is back in the car?
Furthermore I would like to know if it is possible to integrate/code a used instrument cluster and how this can be achieved.
Is that something that only the dealer can do or is it possible to do with GDS2 and a VCX Nano interface?
