I'm getting a curve ball thrown at me right now. My girlfriends truck is giving me major problems. Before we met there was a charging problem. The Dodge dealership didn't catch the simple wire on the back of the alternator that was cut. However, they changed the ECM out thinking that was the problem. Well things have gone down hill since then.
I met her in the mist of them so I'm still trying to catch up on all of them. When they replaced the ECM the first time around, they charged the batteries which got her home. It then died again. So they trailered the truck back to the dealership and replaced the ECM again. They still had not noticed the wire cut. So the truck, again, died. They took it back adn this time found the wire. However, ever since all this happened things just keep getting more interesting. To start I'll give you a list of things done to the truck.
Its is fairly stock. Had Edge Jammers in it but are back to stock. Wastegate is plugged. AEM intake, turbo back exhuast, FASS 95 and she runs a smarty. The lift has nothing to do with these problems but it is still there. It had an Edge Evolution on it but that is also gone. I ckecked all connections involved with that and all are clean and covered and what not.
Now when I first got my hands on the truck it had 3 codes. P1682 (Voltage low for the charging system) P1693 (DTC detected in ECM) and P1694 (No bus messaged recieved from ECM). The 1693 referes to the 1694 and the 1682 I'm not worried as we have resolved that. When I first started working with the truck, it ran the standard Smarty, no revo. Now is when it gets interesting.
When Downloading a tune onto the truck, it would program the truck fully. Upon updating the ECM It would come back with a ERROR 61. Bob said this had to due with the no bus communication with ECM. It told us program aborted BUT, the truck was programmed. If you put it at #3 it was programmed for that. The kicker here is the ECM would always read as stock tuning was programmed. Now, if you program up to a higeher level the truck would do the exact same thing as mentioned in the before programming. However, if you programmed down, it would say communication timed out and the truck wouldn't start. You would have to disconnect the batteries and then reconnect them in order to get it to run.
I decided to update the smarty to the Revo seeing as there might be an update. Now it goes through the whole thing and comes up with and ERROR 14 which from what I was told is also a no bus communication with ECM. All the rest is still the same. Upon driving it we ran into a problem. The longer we drove it, the more it wanted to fall on its face. Before in 1st or reverse you could just let the clutch out to get it rolling, now it falls on its face and stalls out. Its to the point where we couldnt drive it with the smarty on so I had to take it off.
Now upon resetting the DTCs they have not come back up but we know the ECM is not updating properly. So where do I go from here.
The other kicker to all this is that the "wait to start' light aint working like it should. If the wait to start light doesn't come on then the truck won't start. The Dodge dealer told her that due to the fuel pump she has, it not going to work correctly all the time. I don't see why that FP shouldnt kick on but sometimes it doesn't want too. That maybe a wiring problem but I have gone over the whole harness to find nothing out of the ordinary and put my FASS 150 on and it does the same thing. Last I knew the "wait to start" was controled by the ECM only going back further to the ECM.
Between the codes and problems I'm seeing its throwing me for a curve ball. I have a feeling I'm going to have to go through this thing one wire by one wire but figured I'd throw it out here first and see what the collective mind could do. Any help is appriciated and thanks in advance.
