Now to figure out how to expand on this to get a manual transmission to work with it... hmmmm.
So when you updated the 2011 BCM with new software for a VIN with remote start you didn’t get VIN mismatches?I just had some more fun with this project. I updated my original 2011 BCM with the newest calibrations & software available using the VIN of a 2011 Cruze with remote start through the AC Delco TDS system. It definitely updated my BCM, as installing it provided me with an actual configuration setting through my radio to enable/disable remote start. With a 2014 Cruze remote start compatible hood latch installed, it would not work and my car would report the hood ajar. Switching to a 2011 cruze specific hood latch taken from a non-remote start enabled vehicle ended the hood ajar error and allowed remote start to function.
So here are the requirements to add factory remote start to a Gen 1 Cruze:
2011 Cruze ONLY- a bcm programmed for remote start pulled from a 2011 cruze, or your original bcm reprogrammed using the vin from a remote start enabled 2011 cruze and key fobs that support remote start or onstar module programmed for remote start.
2012-16 Cruze - a bcm programmed for remote start pulled from a donor vehicle, or your original bcm reprogrammed using the vin from a remote start enabled cruze, remote start compatible hood latch (P/N: 95463828 or 42522220) and key fobs that support remote start or onstar module programmed for remote start.
