Pulled a load this morning after changing the Battery's both were bad but were still starting the Truck ... No Errors so far .... could this just be symptomatic for all this computer errors having similar problems in my Chrysler 300c it has never had a battery change ... any help will appreciated. ????

 

Had my truck since 2006. No major problems until last year when P1755 poped up. It took me a long time and many parts to pinpoint the ECM which I refused to think of in the first place due to the high replacement cost. But that's what the problem is, your ECM. I drove the truck with that code for a while and few months back I got even more codes and now I found the ECM to be filled with corrosion. Need to buy a new one. Like I said, I already replaced a bunch of tranny parts, batteries and so on. That didn't help.

 

need a wiring diagram for ttva and ECM C1 and C2.
