Ford BCM programming

I don't think it is possible to turn a engine off and leave the ignition on at the same time. So just to clarify a few points before I go do this. Dont sound right And how is one supposed to turn the engine off but leave the keys in the ON position without turning it to accesories only first? EDIT:2nd part of the last question was covered OK, but will it stuff the learning process if you put it in park and turn the engine off turning keys back to ON then change to D and do the throttle full open position??

Posted: Wed Aug 17, am. Getting Side Ways. Yes I found this thread the other day while doing a search as despite what people have said, that all you need to do to reset the ECU is just a matter of taking the Negative off the Battery for 2 hours or overnight then re-connecting it and then thrash your ride for the next 2 days.

Nooo not at all!New bcm installed. Performed parameter reset in security. Still have 3 PATS codes and no crank. Less than 2 keys programmed, PAT target identifier not programmed, and transponder missing message. Checked bcm part number is correct. What am I missing? Thanks in advance for any and all input. Go into PATS gain security clear all keys, program 2.

Go back into security another 10 minute wait do a parameter reset. Keys must be programmed first before performing parameter reset on some models. You should be OK. I just dealt with this on a F last Friday. Non PATS vehicle, non transponder keys. Back story. The client shop diagnosed a faulty BCM. They also attempted to take it apart.

I initially couldn't enter security. IDS prompted fault found. Diagnosis found high resistance on the ISP-R circuit of pcm. Found damaged wire and repaired….

I have never seen a non PATS vehicle of that year range. Maybe it is rare?


I remember hearing a story a while back about an oddball Ford having to have a special as built data provided by Motorcraft. I wouldnt think PATS could be programmed out with asbuilt but…. I guess Ford figured nobody would want to steal a work truck.Welcome to world's most trustworthy automotive forum.

Reputation: 3, Easy Correct me if I am wrong Fraze, but if you select PMI with old module installed then IDS should "inhale" data and parameters from old module and instruct you when to change module for replacement module and program it without having to use as-built data at all.

I don't even think you will have to carry out PATS programming this way. Help is free when you push them.

5 Common Symptoms of a Failing Body Control Module (BCM)

Fair enough. Things must have changed then. Only used to need as-built data if no comms with old unit, or if module had been flashed with wrong calibration file. All the spec's of the vehicle are in BCM from Tyre size to Alternator output all change able i guess is to update. Easy It did'n work. Replies: 8. Replies: 1. Last Post by Prostar. Replies: 4.

Posted: Sun Feb 04, am. Parts Gopher. I am in the garage now with the new unit plugged in, going by the technical documents section I need to have the ignition in the "ON" position I'm guessinbg that mean when all the accessory lights turn on and waited 30 minutes.

Nothing happened and ofter wating another 5 minutes to be sure I tried to start the car and nothing happened. All it did and still does is show the! The Smartlock jewel is not flashing at all with this new BEM but all the other features such as lightsdimmer function, and antenna height are all working properly, its weird.

I think I'm doing something wrong. Do I need to replace all the dash components including all the plugs for central-locking, boot release, clock, etc, first? ACT Cruise Moderator. By, on they mean not accessories position, but the next one. You may have to hook up all the dash components, because the rear demister button is part of smartlock too sneaky buggers. Yeah, its at the correct position by accessory lights I meant the test lights in the instrument cluster The Demister is used to tell the BEM to learn new Remotes, but mine never worked so I thought it wasnt a problem.

I'll switch back to the origional BEM while everything is still apart and try again to see if it will start. I sat in the car last time with a stopwatch going and I heard a few relays clicking in the dash at about 20mins and 40mins approx, I'v forgotten already but no smartlock jewel is flashing.

I have left it sitting there for the last 3 hours and still nothing. Stupid thing. IF the doors are open they may not work. Leave a window down.Remember Me?

What's New? Results 1 to 13 of Thread Tools Show Printable Version. So after much adoing and afroing, along with the 'Expert' opinions from all and sundry, He ended up at the Ford dealer and the head mechanic told him the most likely cause was the BCM and to press lightly on it.

He added this was a known fault with this model. He hasnt, of course I THINK this bcm is located at or under the centre console and am I guessing corectly it contains the Isolating switch to stop you starting the motor if the selector isnt in either Neutral or Park? If he gets another one, is there any tricks in replacing them other than maybe disconnecting the battery?? I was also intrigued to be told if you remove the dome light, it acts a 'KILL' switch??? Any ideas please?? I had an EF Fairmont and it was a shitbox, everything that could go wrong, did go wrong.

Then again it had been neglected by a farmer before me and had done km so I shouldn't complain. I sold it to a mate who still drives it and often thanks me for fixing all the problems with it. One of the things I did that made a few things better Rough idle was the biggest was to replace all the electrolytic capacitors in it. Don't even bother testing them, there's only a few and they cost bugger all - just replace the lot. It may fix nothing but then it may - a cheap shotgun approach that may work.

I had the legs rotted off a few in mine. I will have a look tonight at my Ford EF manual for any tips when i get some time. I have nothing to add to this apart from my old man is selling his EF Fairmont with over k's on it, he put about k's on it and nothing but the head has failed!

What is happening to the brand?

I would suggest buying a new car, from what I'm hearing they all seem to somewhat of a time bomb, everyone I know with a EF 4 people are all starting to have little quirky problems pop up, regardless of how many k's they have.

Have a read of these posts with similar problems. Get yourself a test light, poke your head under the dash on the center console side of the steering column and look up. You will see the plug for the BCM. These are the starter wires. One is power coming from the ignition switch when in start position, the other is power to the starter relay.

Check for power on these 2 wires while trying to crank the engine prefferably when it is playing up. If you have power on only 1 wire, then the BCM is stuffed and you have 3 options. Option 1, replace the BCM. This requires reprogramming of the ignition switch to the new BCM no big deal. This will bypass the smartlock starter cut out, but the smart lock will still stop the engine from firing if some one tries to hot wire it. Option 3, sell the ford and buy a Toyota Have a read on this forum that im a member on.
