2002 Dodge Dakota 3.9L. 2wd. I have put a different PCM on the vehicle after it stalled. So now it runs but still has the "no bus" message in the odometer, and none of the gages work. If you have the solution, please let me know. I would consider myself to know enough about the motor to be dangerous. lol.

 

Did the original PCM have the same issue?? Where did you get your PCM from?

 

Well, when I bought it from a guy, he said that he had gotten the PCM used from a similar truck. He said it quit stalling and has been running good ever since, but the dash instruments still don’t work. With the original PCM, the vehicle was quitting, unexpectedly, he said. Please help

 

Then something else is going on in there. Cluster isn't getting info from the PCM.
