Mike?Is there a Chip that will ignore the Anti-Theft "Interlock"
Mike(or anyone who can help me)Please:
I'm sorta new but noticed you seem to respond to questions about chips. My originally equiped anti-theft "interlocks" the ignition (and probably the fuel injection circuits) so that the starter will crank but the engine won't start. I've been satisfied with my PU for almost 4 years (zero problems)-- and love this 4.6L engine design -- but was unaware of this feature of the anti-teft system until it failed. None of the circuit information I have (ford and other shop manuals) shows any hardwired interlocks that would account for this - believe it must be the Data Link and think it is signal(s) from the Lighting Module(LCM)to the PCM. The PCM has checked out good on the shop's computer (no faults or messages). They "reprogrammed" by operating the ignition switch 5 times (at which point the door locks jumed down and up automatically) and then operated the RAP key fob through a sequence -- that worked for 1 day, failed again, and now won't "reprogram" this time.
In my opinion interlocking the start circuits for almost any reason is BAD design and am determined to dismantle it. There must be a way to "jumper"(program a jumper) such that it works as though there were no Anti-theft option on the vehicle. Ford shop is reluctant to pursue (or doesn't know how), so I'm not satisfied with their responses to my questions, which don't have the ring of truth (they just ant to change out modules until they fix it -- I want the design changed). Is this a function of the/a chip in the PCM, which could be replaced with one which would ignore the anti-theft signal,or is it in the PCM internal "wiring" or external connections? I would appreciate any help.
Thanks,
Doug

Hi Doug,
Sorry, we can't help you with that.
I'm not surprised in the least that your dealership won't be of any help with regards to any "redesign", that isn't their function, so that isn't going to happen with any dealership will most likely, they can't and aren't going to do any "redesigning" of Ford's products, nor assist in any such activities I'd bet. They sell & repair them, and that's pretty much it.
Things fail, things break, that's life, and with increasing vehicle complexity comes increased repair cost upon failure out of warranty. I can certainly understand that it's aggravating if the dealership is not getting it fixed, but I'm not sure from your post if they really can't erpair this properly, or if you guys are just at loggerheads over some possible insistance that this be redesigned for you; they aren't going to do any redesign of this on your vehicle, that's a safe bet, I'd say. You already realize that by now I'm sure, so you don't need me to tell you the obvious.
To directly answer your question, no, we do not do anything to defeat the anti-theft system or to bypass it in any way. Its functions with regards to any involvement with the powertrain programming are left fully intact in the Superchip.
If your dealership cannot seem to get this fixed, take it to another dealer, and if necessary, get the factory Zone Rep. involved until its repaired properly, at the correct cost to you, without you having to pay for them to experiment.
I'm sorry I can't be of more help to you Doug, I know this must be frustrating for you. All I can really say is good luck, I'm afraid. So I'll just close by saying..........
Good luck!

It is a function of the PATS or passive anti theft module not the pcm. It is multiplexed with the pcm to keep the vehicle from starting but the problem most likely lies elsewhere. You cannot bypass this system without causing problems elsewhere and if the dealer were to somehow "change the design" they would be liable for any problems or saftey concerns that would arise from this "design change". they should be able to fix your vehicle though and that is something you can hold them liable for but ot hold them liable for not redisigning your vehicle is wrong. Now, do you have PATS keys and key fobs? if so this is two different systems and you problem lies in the PATS key. there is a chip in the key that sends a signal to the PATS module to allow the vehicle to start.... The key fobs mainly just lockc and unlock the doors, and also turn on the interior lights. There is also a panic button to activate the horn in an emegency. Sounds like a PATS key problem if the vehicle cranks but wont start...

The multiplexd signal you mentioned, is it a signal over the "Data Link" shown in the shop manual as interconnecting the PCM with the LCM, the Door Module, and the Seat Module? If so, I wonder which one of these modules determines that an armed condition has been violated and therefore telling the PCM to interrupt the ignition system.
With the door(s) unlocked the system should have been disarmed according to the owners manual. Wonder why this armed-interrupt would not show up in the PCM (or data link) connected to the shop test computer as a "logical problem" in the diagnosis done by the computer program?
Thanks again,
Doug
