Hey guys, I got an 2006 gmc lbz and recently when ever I have tried to engage cruise control over 100km/h the cruise will kick out and the gauges will all jump and codes will appear. Codes that appear are P0606 and P0852. How ever this does not happen if cruise is set under 100kms or if I keep my foot held on the gas pedal. The Moment I release my foot from the gas the codes appear and the truck kicks out of cruise. Sometimes it even killed the truck and won't let it restart until the key is cycled. Has a PPE tuner.
LBZ: Engage cruise brings up codes and kills the truck!

P0606 is an internal ECM fault code.
Have you removed the tuner to see if it continues to fault?
