I am speaking from experience updating processors for Jaguar and Jeep/Chrysler. Does GM have the capability with Tech 2 to scan all on board processors and indicate if updates are available? I'm inquiring with servicing dealer if all my processors can be scanned and updated. So far I'm being told there needs to be a complaint for certain processors for updates to be performed so I want to identify all onboard processors and have complaints ready to have all processors updated. Off the top of my head, I can identify a few, ECM, Transfer Case, ABS, Restraint System, BCM,TCM, Stability Control, Cluster, Lighting... Does anyone here know for sure the processor count?
