TimberJack Posted December 1, 2017 Share Posted December 1, 2017 Has anyone had this code? Says power relay, so I changed the 4 power relays in the dash and still nothing. Took the truck to dealership and after $2050 bc the fried the ECM I still left with the same problem. Quote Link to comment Share on other sites More sharing options...
Mackpro Posted December 2, 2017 Share Posted December 2, 2017 The troubleshooting manual point towards the engine ECM if the power relays don't fix it. The dealer can get you a troubleshooting manual for the ASET family of engines and their pretty cheap Quote Link to comment Share on other sites More sharing options...
TimberJack Posted December 2, 2017 Author Share Posted December 2, 2017 This is the truck I swapped the AC motor out for a E7. I wonder if that’s what’s causing the 6-7 code? Quote Link to comment Share on other sites More sharing options...
Mackpro Posted December 3, 2017 Share Posted December 3, 2017 Yes it could, best I remember, the code is for the VECU not powering down the engine Ecm correctly. And since your replaced the AC EECU with one-off a AI/ETECH it could cause it. Quote Link to comment Share on other sites More sharing options...

TimberJack Posted December 5, 2017 Author Share Posted December 5, 2017 Well I figured out if you start the truck and shut it back off and restart before the dash loses power the code goes away. Quote Link to comment Share on other sites More sharing options...
TimberJack Posted December 5, 2017 Author Share Posted December 5, 2017 I also changed the module behind the plate in the passenger side floor board. Quote Link to comment Share on other sites More sharing options...
