The link above should take you to rock auto for the pcm's i'm looking at. the pcm my truck has is the same as the 180$ one. my question is what is the difference between the pcm's and can i get away with the cheaper one. attached is a photo of the burnt out component and the pcm model number. wanted to get some feed back before i bought the new one
in my pcm and the model. wanted to get some feed back before i bought the new pcm.
1999 PCM would only be concerned with engine size and transmission, manual or automatics used different software, there was no PATS in 4cyl Ranger PCMs until late 2001 2.3l Duratec models
Ford PCM part numbers work like this
X = 1999 year of part
L5 is Ranger
F = electric engineering department
12A650 = Ford part number for ANY PCM for any model since there were PCMs, i.e. 1985 PCM uses this part number as does 2019 PCM
ARB is a firmware revision, AA would be first revision
The BIG added number to label GAJ1 was the software loaded to this PCM when it was installed, same number should be on a label in engine bay
The Firmware and software are important it will denote manual or automatic
I'm currently tackling the cause of the issue. Just rewired the primary coil cause the previous owner had cut it out and did some really bad wiring. I feel pretty confident it was his really bad wiring that caused the issue cause where he spliced the wires together they where blackaned and looked pretty toasty. Since then ive rewired the primary coil back to stock and have all the wiring buttoned up. I've tested all my others wires whike I was in there and nothing was grounding out or shorting so hopefully I don't fry my new pcm haha.
thanks for all the info
I feel confident I'll buy the right one. Thanks :)
