Had a 2011 express van gm with a dura max diesel. Ultra with latest updates would not clear codes. I tried multiple ways and kept coming up with the message codes ds not clear. This was for PCM. Ended up having to use a 19.99$ code scanner and cleared codes in 30 seconds. Anyone else had issues with this or do I need to call support.

I tried going through PCM and glow plug module to clear. Tried disconnecting batteries over night then starting new session next day. I did not try global obd2.Comment

It had a hard fault for egt sensor 2 stuck at 1300 degrees. Replaced sensor and rechecked and it was ok. Vehicle was stuck in fail safe mood for scr system. Hopefully fixed by next updateComment
