Yes, that's why it's the first thing I recommend any time someone mentions REP without codes.

You don't have a TAC module like a GMT800 body does. The throttle controls are in the ECM on yours. The TACM is a non-Class2 module that has a dedicated communication circuit with the PCM that is not on the scanner besides reading slave info through the PCM. When a weak battery causes one or the other of the PCM/TACM to wake up before the other you get codes because they expect to both be online or offline.
