I didn't bother watching more than two minutes, but I can tell you that it's the 'hard' way. If your repair procedure required that the battery be disconnected anyway, then the KAM is already reset and further action is not needed. ![]() Instead of messing with the battery cables and a jumper, all you have to do is locate the fuse that supplies KAM power to the PCM. Ensure the ignition switch is in OFF, then pull that fuse and walk away for 5-10 minutes while you do something else. Come back and reinstall the fuse. You won't have to reprogram the radio and such and the PCM's memory has been been completely cleared so you can start over with the 'relearn'. Here is the problem there are many powers and grounds to a pcm. Also many vehicles have a seperate tcm for the trans. There are too many ways to back feed to pcm that way. You ever hear about the issue with the bad FDM on f150's and how they backfeed through the non powered buss side and take the pcm offline etc. 2011 Ford Expedition Pcm Relay030000 BRAKES (PWS) bulletin for the 2017 EXPEDITION. WORKSHOP MANUAL (WSM), SECTION 303-00 HAS BEEN REVISED TO REFERENCE. TRANSMISSION:CONTROL MODULE (TCM, PCM) bulletin for the 2017 EXPEDITION. Jan 7, 2018 - December 19, 2017 TO: All U.S. Ford and Lincoln Dealers SUBJECT: Customer. Please follow the Workshop Manual (WSM) procedures in Section 414-01. Reprogram the powertrain control module (PCM) using Integrated Diagnostic. Service Information – 2018 Ford Expedition & Lincoln Navigator. As others who have questioned me on this and said they could just pull bat neg and hit the brakes or turn on headlamps that would deplete any power. Well that may be on older direct wired cars, anything new everything is low side ground controls not power, so a ground get sent to a module and the module in turn turns on the head lamps etc, well if the module is not powered how is that going to happen? There are too many variables, and just pulling the kam fuse is a lame attempt at finishing a repair the right way. There is a reason the trans gods at the ford dealerships swear by this method and still stick to it to this day. Anything else is half *** in their eyes, and going through all that work to pull a trans out of a rusty car and rebuild a trans perfect then to slack off in that regard is not smart. It would take longer to find the right fuse than to just pull negative and jumper it. This is the absolute correct way 100% any model or year done, nuff said. ![]() Thanks for the great video and clarification on the reset procedure for the PCM Last time I just unhooked the negative battery terminal and waited 30 minutes. The jumper makes perfect since to me and will use it next time. I used Haynes manual procedure for the relearning: Start and let idle for 1 minute at normal operating temperature Then turn on air conditioning to MAX AC for 1 minute at idle Drive for 10 miles using normal driving habits I must admit your way sounds more thorough and will do it next time on my reset. For the KAM line yes there has only been one line for as long as I can remember, but there are other lines that are hot at all times too. Hence this statement from ford in the diagnostic manual as it is the only fool proof way. 2000 Ford Expedition Pcm Relay LocationHino 700 specification. 'This function may not be supported by all diagnostic tools. Refer to the diagnostic tool manufacturer's instruction manual. If an error message is received or the diagnostic tool does not support this function, disconnecting the battery ground cable for a minimum of 5 minutes may be used as an alternative procedure.' I don't know about others, but I found the 5:12 minute YouTube video jumpy, and the audio was out of sync with the video. There were also many gaps where the audio jumped ahead and whatever was being said was lost. But the general idea seems simple enough. So, let me see if I have this correct: The object of the video was to show how to jumper the two vehicle battery leads together to drain the caps in the PCM, by disconnecting the negative battery lead and jumping the lead itself (not the battery terminal) to the positive battery lead (red cover in video) while insulating the negative battery terminal (not the lead). I will be removing/replacing my battery in a few days. I'm thinking that after it is removed, to just jumper the two leads and let sit for 10-15 minutes to drain the caps. Then install new battery and go through the method described in the Chilton manual Section 5-1 for the PCM re-learn procedure. So, let me see if I have this correct: The object of the video was to show how to jumper the two vehicle battery leads together to drain the caps in the PCM, by disconnecting the negative battery lead and jumping the lead itself (not the battery terminal) to the positive battery lead (red cover in video) while insulating the negative battery terminal (not the lead)Yup.
