Crossed a custom vehicle today that has a 2009 Escalade PCM/ powertrain.

The car is attempting to be smogged but has a not ready on the EGR system. However, the 6.2 shouldnt have an EGR . Attempts to force the system to No error report don't make the system become ready, however it should be N/A. The owner was working with the dealer who was of no help after 2 different PCMs were tried at 2 dealers.

I know how to make this work, but it cant be done with HPtuners currently. Either the required DTC is not listed or it is using a name / code that isnt for the EGR.

Help.
