It would function, just a lot of codes continuously being generated. Ive thought about it over the years, and it seems like more trouble than its worth.
Yep, you'll get a ton of fault codes but you'll also trigger a fault from every module if you upgrade your radio, amp, add satellite or even unplug a component and plug it back in if the power is on while it's unplugged. It's like a teacher takin attendance and if you're not there they phone home or your cousin is there trying to pass off as you. This is where they get you, you have to go to the dealer and pay to get the StarScan hooked up and get it to acknowledge the upgrade.
The problem is I don't think there's an ATC head similar to the factory unit on the CAN bus system that has a regular instead of dual zone control. Otherwise you swap a wiring harness and splice a few wires, recalibrate then hookup to a StarScan.
