An Expert’s Note on Programming
As a technician with over two decades of experience, I’ve seen countless vehicle owners waste time and money on used ECMs from salvage yards. The problem is that an ECM is not a simple part you can just swap. It’s the ‘brain’ of your vehicle and is coded specifically to the VIN it came from. Installing an unprogrammed module will, at best, not work, and at worst, create a cascade of new error codes. By purchasing a pre-programmed 2009-2012 Colorado ECM 12636659 from us, you are bypassing the single biggest hurdle in this repair. You’re getting a part that’s electronically identical to a new one from the dealer, ready to get your vehicle communicating correctly from the moment you install it.
