2007 yukon pcm

[wygren]

I have a 2007 Yukon rental from the dealer (My LLY has a trans leak) and im trying to check the pcm calibration. The error msg is (EFI Live cannot communicate with the pcm).

Is there a fuse I need to pull?

EFILive does not support communication with that vehicle at this time. More than likely in about a month or so it will.
