Sure hope someone has some good ideas!
I own a 1999 Dodge 190V that I bought new. Two years ago I got the dreaded "no bus" error in the odometer. After the dealership gave up, I suggested they put in a refurbished computer from Mopar. That seemed to solve the problem.
This summer I had an off-road shop weld on a new front end to replace the rusted out one, to the tune of 12K. They took the old computer off before they started the work. Did a good job, but after putting everything back, the van would not run, unless pin #5 on the OBDII port was shorted to ground.
This is the "signal" or "sensor" ground, according to my research. I was able to get the engine to run by jumpering the ground wire from the camshaft sensor to a known ground, but the jumper gets quite hot, so there must be a lot of current going through it.
The shop bought a computer from Auto Zone, then took the van to the dealership to have it flashed. The dealer has had it for almost a week, and can't seem to program the computer.
The van is 400 miles away, and I'm not sure what to do. It's driving me crazy, and I'm starting to lose sleep over it!
Anyone have an issue like this before? I'm thinking the old computer was not getting a good ground somehow (although I checked the wiring harness with a multi-meter and it seemed like it was good to ground), but why the dealer can't flash the new one is beyond me. They claim their technicians are young, and don't know how to do it!
