Diagnostics manual says this:



I do recall seeing this code pop up for someone else on the forum a while ago. I couldn't begin to tell you what went wrong, but it has something to do with the drive motors providing torque when the engine is running in Neutral (or Nuetral, if you're the person writing the manual...), which obviously should not happen.

Is your car still driveable?

EDIT: The conditions in the manual are pretty confusing even for me, a computer programmer, but it looks like it may be possible for this code to throw if the car's in Neutral with the engine running for longer than 33 seconds regardless of what the motors are doing.

One possible scenario I can see causing this would be to shift to Neutral while the engine is on (Hold or charge-sustain mode) and then come to a stop, as I don't believe the engine will shut down in Neutral in this case. Did anything of the sort happen...?

Arcanox are you telling me the car has a motor. That's not it the last time the motor ran was about 8 months ago, I do alot of short trips the car is running fine and my mileage is still between 74 and 80 on a charge. Onstar was no help, I asked if I should drive it or park it and they said call the dealer
I was merely listing a condition that might trigger that code. If the engine was never running, that particular case wouldn't have triggered it, but something did. Something happened when the car was in Neutral (or thought it was in Neutral) involving one or both of the motors, triggering this code. I wouldn't let it go, because it could indicate a problem with the transmission. If I were you, I would schedule an appointment sooner rather than later.

Good advice, I have an appointment for Wednesday to replace the outside antenna (No FM) so the service writer said they would clear the code but they have seen it 3 or four times before and it's a programming problem and their is no fix at this time but they will make sure everything is ok. Also I was very rude in not thanking you for the print out so THANK YOU
You're welcome; I forgot to post the link to the manual with the codes: https://service.gm.com/gmspo/mode6/pdf/2016/16OBDG01 Hybrid Diagnostics.pdf

There is no way that your motor could have last run 8 months ago without you also being out of fuel. It runs every six weeks, at minimum.
That's a good point, I forgot about EMM since I've never had it happen on mine.
