I'm a newb at this but I have a very limited intent in that I am not a full time mechanic nor want to be. I have a 1998 grand cherokee 4.0 auto trans 42re. In the process of pretty much fully restoring it. I just really like this jeep and being 55 years old want it around as long as possible.
I have spent a month or so studying the pcm,functions, programming, tools,ect. I have over the years aquired several used pcm,s that have the same part number as mine. Mine is running great at the moment but I want to have functional spares.
I want to be able to program my vin and mileage into the used pcms. If they happen to be the alarmed version thats OK cause I'm capable of adding any needed circuits. I think I understand that these pcm's allow the alarm to be enabled but not off. Also that I may need a 4 digit pin to go anywhere with it.
I have learned how to repair the pcm's to a certain extent, but know I have alot to learn. Looked at the drb3,cardaq plus, and another bench top programmer that has the pcm connection harnesses{which are expensive}. Could you guys tell me the best course to follow to achieve this end? Again I'm not trying to make this a money making affair or become a tech,just want the zj around for a long time. Thanks if you choose to help!
