It's a miracle...all fixed! PCM was fine. Mechanic called and said car all fixed. He ordered another key and reprogrammed it. Not sure why the locksmith that came was not able to fix it. He had told me he was not able to communicate with the PCM...but regardless it's all fixed. Thank you to...

Who here has changed a PCM on a 2004 Ford explorer XLT 6 cylinder? Need info on taking out the PCM. Send it off for repair or buy another? Think I'm about ready to send it to the mechanic.. ugh

Put in a new battery. Got that done today. On to seeing what to do next in this fiasco from just having a battery drain and fixing a brake light switch on the pedal.

Looking at the PCM on firewall..it see one bolt near the top of it. Is it supposed to slide straight out? Seems to have some type of sealant around the outside edge so wondering if it should slide out easily. Who are the reputable companies to order a PCM from? Thank you

What powers fuse 29 in central junction box? This fuse is for the digital transmission range sensor. No power at this fuse with key on or key off. Or, is there only power to it when the car actually starts up?

Discovered fuse #29 (Digital Transmission Range Sensor) underdash drivers side no power. Used a test light and both sides of fuse showed no power. Tested with key off and with key on. But to the eye the fuse looks okay...not seeing a separation of the metal inside of the fuse. If I understand...

Do you know if just a standard code reader gives PCM codes? Curious to see what codes I might get if I get a reader to make sure there are no other problems I'm not aware of. Wondering if PCM just went bad or what could have caused it to go bad so if anything, it doesn't make the replaced one go...

Okay...so get a PCM with matching part number and install it. Have locksmith come back to add my key (only have one though). What about the programming of the PCM? When bought, are they normally preprogrammed to the VIN before they are installed or need to be programmed upon the install...

If it's not a power issue, or other problem, and it is a bad PCM, what's the next best step? I've heard a PCM, transceiver and keys can be bought and it comes preprogrammed to the cars VIN. How successful are these "plug-n-play" versions versus having to go to a dealer? What would be the best...

Thank you. I'll look for this.

Going to take the battery to a different place to be checked. Sure is acting like it might be shorting itself out.

To add ..I don't know if that recall was fixed by owner before me.

Been busy and had some time this morning to check a few things. The wiring diagram shows connection between the PCM and redundant brake switch then to the brake pedal switch on the brake pedal. It seems from further looking that the redundant brake switch was recalled due to fires. Could...

I cleaned the ground days ago but found this video in case it helps anyone. Not in English but guess he's cleaning a ground wire.

With key on discovered I have code 1:5 which is Key not programmed to PATS Programme key . But since locksmith yesterday couldn't connect to PCM guess I'm up the creek without a paddle ..

No tester here at the moment and will have to check it. I connected my battery maintainer to charge it back up and it turns off when it reaches full charge. Battery dial on dash shows it in the range it normal is in which is above the half mark.

Advance Auto test showed battery was good but maybe it's possible that was not correct. Perhaps something with battery cables IF the battery test was accurate. If voltage is the culprit then loosing power somewhere after battery is connected IF this battery is good like I was told. The book...

Will check around for PCM unit price checks. Don't know the company but heard Flagship One carries them with lifetime warranty. I unhooked the negative terminal for 5 mins and replaced. the wacky flashings in the cluster stopped and went back to what I had before aka all lit and rapid flashing...

Oh ok.. so it's getting power but not communicating..

I took battery to an auto parts store to be tested and was told it was ok . Told it needed a little more charge (I didn't fully charged it before taking it for test) and was told the test would say if it had a dead cell or not and he said it didn't. That day I was told it was at 12.5 v. I'm...

Locksmith came and did the following:: Attempted to parameter reset could not connect. Hard reset, same results, checked key and antenna ring, both functional. When first connected it showed three keys in system. Was not able to connect to PCM. Then he tried further but to no avail. Tried also...

Okay, thanks again. If PCM has cleared it..makes sense.

I only have the one key for the last 5 years or so that I've had unfortunately. Ace Hardware read the key which means key is good but since the car is not reading it that's what you mean? Not one in system because the pats some how deleted it? I asked locksmith yesterday about keys and was...

So far only one transceiver here locally if it's the correct part and they said they can't verify the part number until Monday. Having to see if one from a 2002 Explorer XLT will work in 2004. So it's down to getting transceiver or just having locksmith come out and give it a whirl. When...

Just to see what would happen. Put key in and turned to on and left it there. After a minute the rapid flashing changed to slower then after three minutes of blinking it stopped blinking totally. May mean nothing but sharing info. Okay.. good to know. Also, just to see what would happen...
