Macktech689 Posted June 7, 2014 Share Posted June 7, 2014 If your diagnostic tool cant communicate check the fuse and power supply to the engine control module. 1 Quote Link to comment Share on other sites More sharing options...

wheeler73 Posted June 7, 2014 Share Posted June 7, 2014 Could be a module causing the issue. ABS, vecu, eecu, and any other modules and gps units tied into the commu ication lines or the J1939 connector under the hood and the harness connector on top of the trans. Definatly need to know what the blink codes are. Quote Link to comment Share on other sites More sharing options...
Dirtymilkman Posted June 8, 2014 Share Posted June 8, 2014 Take the fuse/relay box off of the firewall under the steering shaft under the hood. I bet there's green corrosion on the back of it. I just went through this. Quote Link to comment Share on other sites More sharing options...
Tgulley Posted June 9, 2014 Author Share Posted June 9, 2014 The blink code is 6 4 Quote Link to comment Share on other sites More sharing options...

wheeler73 Posted June 14, 2014 Share Posted June 14, 2014 Done lots of those recalls. Unfortunately it does not involve his truck. Quote Link to comment Share on other sites More sharing options...
j_martell Posted June 15, 2014 Share Posted June 15, 2014 Mine falls under the recall.....i know it's gonna vary from one dealer to the next, but is it something they would fix while it's in for something else, or not until its in for one of the symptoms?

wheeler73 Posted June 15, 2014 Share Posted June 15, 2014 They need to fix it when its in. We check all trucks for recalls and safety campains and complete them. You can bring the truck in for just that if you have no other work to be done on the truck. We do it all the time. Quote Link to comment Share on other sites More sharing options...
j_martell Posted June 15, 2014 Share Posted June 15, 2014 K. I'll have a look. It been in ALOT in the last little while for emissions crap. I don't get to see the invoices as to what was done, but I'll have a peek and see if it's been done. Quote Lack of planning on your part does not constitute an emergency on my part....
