1980 Mercedes Benz 280SE Base 6 Cyl 2.8L
is a pcm ( module) interchangeable in 2 dodge dakotas?
My dakota starts well but wont run, then 'no bus" sign appears. I suspect my pcm so i want to try my friend's pcm on his own dakota same as mine
The PCMs may be interchangeable to a point - depending on the year, the engine size and specific transmission. The PCM will still need to be reflashed / reset-up by the dealership to be correct for the vehicle it's installed into - and calibrated to the specific vehicle components. The PCMs are VIN protected so unless you flash it you cannot go from one vehicle to another. There is another consideration - the security code - some vehicles have the security code in the PCM, and some do not. Those PCMs with secuirty code will not easily interchange with a PCM without.
