Simply hooking up to the scan tool or scanning for codes etc will NOT yeild a TD1. A specified/actual test WILL. This is a process that the technician must start in the scan tool. They could also manually enter it they know you are tuned and want to be dicks... Also, an ECM update will likely catch you with your pants down. I know first hand, a 24AP ECM update will end badly. Not sure about the newer 24CO update, but assume it also will get ya. Chances are for a routine maintenance etc, you'll be fine. No need to do anything but reset the service light and may be check and clear ECM faults with a service. Go to someone you can trust...
