After getting a code that said the pcm, quad driver was bad found a donor car that I know had a good one is there any trick to changing them? it is for a 95 cav. 2.2 , 3 spd. auto and the one I got came from the same year and the numbers on it matched. Outside of unplugging one, and plugging another one in is there anything else I need to do. Thanks
hows it going tim, I am 100% sure all you got to do is plug it in, And youre set.
Good Luck.
Disconnect the negative on your battery first! After installing the replacement PCM, reconnect the battery, and drive as you normally would for the 1st 100 miles so the replacement PCM can do its "learn" thing, all ought to be good thereafter.
Going to install it this morning and see what happens Thanks
haha, go waste your money my friend. I laugh at how people can be stupid/ignorant sometimes.
A quad driver on the OBDI Ecm can be as stupid as a burned shift light. Before thinking the ecm was bad, reading the code is not enough, you should have went throught the 2-3 pages of diagnostic for the quad driver.
I had quad driver code before. 1 was a burned shift light, the other was a bad selenoid, .... THERE IS NO CODE SAYING THE ECM IS BAD in any J cars.

I checked into the diagnostic code and there are 3 things that can come from that code which is egr solenoid,canister purge valve and the tcc solenoid, figuring the car has a slight rough idle and not as good mileage I guess I'll have to test one of these to see which needs to be replaced. But the way my luck runs it would probably wind up being the tcc solenoid which looks like alot just to change. Thanks
