this is in regards to a 2007 ranger. i am the original owner, and the truck never had keyless entry or any alarm system. a technician from Drag Radial Performance recently made me a P A T S delete tune and was put in an SCT X4 programmer. i recently applied the tune, and according to the X4 it was successful and completed.

the truck came with transponder keys from the factory. with this completed tune, i thought i could easily unplug and remove the transceiver from around the lock cylinder and start the engine. i dont yet have a non transponder key, but after unplugging and removing the transceiver, and reinstalling the lock cylinder; the engine wouldnt start and the anti theft light blinks rapidly and endlessly.

with the transceiver installed and plugged in, in spite of the delete, the truck does start fine. i am wondering, with an official P A T S delete, why is it that the truck still needs to have the anti theft transceiver installed when the programmer disabled P A T S? do i also hafta remove something from the instrument cluster?

 

In 2004 and up the instrument cluster is also part of PATS

Ford started using HEC(hybrid electronic clusters) in most models in mid-2000's
This prevented the cluster swapping, to put in lower mile odometers, that was popular with "used car" salesmen
Odometer number is stored in both HEC and PCM and they must match or no start

Surprises me that the PCM reprogramming didn't bother the HEC, HEC and PCM are "married" at the factory, so one will not work without the other
But if programmer left serial number and odometer the same then maybe thats OK and all it really needs

HEC test info here: http://www.carlogic.org/bg/data/Ford...ler%20mode.pdf

 

so then ron would the instrument cluster be this hybrid one? and if so, are you saying that the tune that was created skipped/missed things in the hybrid cluster, and why the engine wont start without the transceiver?

the tune was created remotely and then 'installed' into a new SCT X4. the guy that made it has suggested i try to re apply the P A T S delete tune. the X4 had two tunes and options for programming. --put them together with the other unrelated tune, or do them separately. i applied both together.

i may soon follow his direction and re apply the anti theft tune by itself.

thank you for the test information, though i already have all that in my ford workshop manuals

 

You have a 2007 Ranger so have the HEC

You are programming the PCM, not the cluster so PATS is still active in the cluster, not sure you can delete PATS from a HEC cluster
So yes that's why you need to use the PATS system

You can try just plugging in the transceiver to it's harness and not put it on the key slot, Cluster may only "look" to see if its connected
These are HEC error codes
B2103 9232 Antenna Not Connected - Defective Transceiver
B1232 A103 Antenna Not Connected - Defective Transceiver

And if that doesn't work then stick the transceiver, still plugged in, under the dash and tape the PATS key to it so HEC is happy, when you turn non-PATS key on

As far as I know you are in uncharted waters as far as PATS and the HEC

I do know Ford Dealers can not just swap HECs if a cluster fails, they have to order one from Ford, and then it has to be "married" to the PCM

 

okay. i will check with the person that wrote the tune to see if he included the delete for the hybrid cluster

what do you mean here about not putting the transceiver in on the key slot? the transceiver has four wires in the harness. being for:

ground
powertrain control module diode relay
remote R F receiver
powertrain control module transceiver transmit data TX out.

--which of those is the "key slot"

 

means plug the transceiver in and not clip it on to the lock cylinder for the ignition. It clips on to the lock cylinder

 

Yes ^^^^

 

alright guys, i did talk to the guy that created the tune, and he said he did set it to include and delete from both 'clusters'. i also tried to remove the transceiver from the steering column though leaving it plugged in. that still ended with a no start situation.

in addition to this, i unplugged the instrument cluster, and tried removing the two related P A T S pins, 14 and 15 from connector 220B, and reconnected the cluster. it was same as before with no start. the tune guy suggested i try to start the engine with the cluster completely unplugged. that also gave a no start. i put everything back together and the engine did start. so, it seems we are still stuck here.

this guy has been very successful in deleting P A T S from other ford vehicles, even suggesting that the P C M plugs are nearly exact among other ford vehicles, especially the mustang. he said he was 96% certain the delete would be successful. so, unless the technicians at S C T are retards, we may be stuck here.

there is nothing wrong with the truck, but i would like to completely disable the anti theft system, for no other reason than vehicle theft not being an issue where i live. i want to completely disable it, remove the transceiver and be able to start the truck with a non transponder key. it is my truck and completely paid for. i am the only owner and the title is in my name.

i also do not wanna simply attach the transponder key to the transceiver with tape, and then use a non transponder key. i want to completely do away with all P A T S pieces. --the transponder key and transceiver.

what else can we do here?

 

Look at this: https://www.motorcraftservice.com/pdf/pats_job_aid.pdf

Looks like Ford was changing the Ranger system in 2007, there are two Types listed, C and G, they each used different keys so you should be able to ID which Type you have
Mustangs didn't use G

And the above pages also shows the Body codes for the different PATS failure modes which you can get with a Reader or from the instrument cluster in Test Mode

Knowing the Type of PATS may lead to a proper delete
And what PATS thinks is missing to cause the No Start

And is the No Start a no crank?
Or does engine turn over and not fire

 

thank you ron. my ford is a 2007, 4 liter with a 10 second light flash. it is a control function type C, with a key of 15. i plugged in the X4 and read the codes. it showed only P1260. ive seen that before after a proper flash and drive cycle. turning the key after a successful flash had no no-start issues, but it did generate the P1260. but the vehicle wasnt immobilized, the engine did start and i was able to drive it.

the no start i mentioned was i guess no crank. i turn the key to start and nothing at all happened. i was in the cabin and heard nothing.

 

Yes, starter motor should be disabled if it is a PATS issue

There are several OTHER issues that can cause a "No Start", but No Starter motor is usually PATS, or dead battery, lol


P1260 is a tamper warming code saved in PCM memory, it can be caused by low battery when starting an engine, or if PATS causes a No Start repeated times, tells owner someone was "trying" to start the vehicle and PATS prevented it
It will turn on the CEL
But if you drive vehicle for at least 15 mins then let it cool down for at least 30min then drive it again for 15min, and cool down again(so 2 drive cycles) CEL will turn off on its own, but code stays in memory
And obviously you can clear the code anytime with a reader, lol

Mustangs did use type C PATS, 1999-2004 it says on the sheet, so I would expect that PATS Delete software to work on the '07 Ranger type C

 

the battery is fairly new, so its not a discharge issue. and the starter motor is in fairly good condition, starting the motor, aside from anti theft hacks.

these recent attempts to disable it, have not caused the MIL to come on, so its not needing clearing from a drive cycle.

what else can be done here for a full delete, and without using the transceiver and transponder to start the engine?

 

leave it the hell alone. seriously leave well enough alone. PATS isn't hurting anything, you go tamper with that and next thing you know your truck will not start period

like you said you unplugged the cluster and the pins, the truck didn't start. there is your answer. Let it go

 

Uhm, okay djfllmn. Thank you for your input here........

 

I think the stumbling block here is the HEC dash, not sure how applying software to the PCM can effect software in the HEC
There should also be a separate software being applied to the HEC

From what I have been reading the PATS system is in the HEC not the PCM, similar to the first PATS systems that had a separate PATS module
The HEC is the PATS module, it runs the transceiver, and has the Key numbers stored in its memory
When it gets a match it sends an encrypted "message" to the PCM to say "OK to Start", same as PATS module did

So PATS delete in the PCM is fairly straight forward, its the HEC that is the problem

 

^this is exactly how it works,

 

well the guy from drag radial said the tune was made to communicate with both. and while applying the tune, i saw on the X4 screen the word marry, which, i would take to mean it was communicating with both modules.

then, even in replacing or doing work with the anti theft system, the workshop manual states work/replacement must be done with the instrument cluster and the power train control module. whatever it is, the two do work together.

is the X4 not a good programmer in this situation?

 

PCM = powertrain control module = engine computer

Yes in 2004 and up Rangers PCM and HEC dash need to be "married"

Marrying, in this case, means each device, HEC and PCM are given an RSA encryprion Key, so they can decrypt each others "messages" like "OK to start", or "Odometer is xxx,xxx miles"(so you can't swap in a lower mile odometer into dash, lol)
The encryption changes each time PCM and HEC "talk" so you can't monitor communications in the system and then reuse an "OK to start" message to by pass PATS

 

well they did get married and talked to each other the last time i applied the tune. but, in spite of that, it seems that the instrument cluster is still doing its own thing. cheating on its partner.

i found out rather late, that anti theft was an option on this vehicle which i didnt specify in the ordering process. would there be anything more to do than either swapping parts or having the dealership reprogram things to non anti theft?

 

dealer ship can not reprogram for non-pats. they can only do ''as-built'' data. And I'm pretty sure by 2007 pats was standard across the board in rangers again. 99-00 only the v6s had it. 01-04 every engine had it, 05 had nothing regardless of engine, 06 was back to V6 only and by 07 i think it was all motors again

 

+1, PATS was standard in all Rangers from 2002 and up, 1999-2001 V6 Rangers also had it, you couldn't get a Ranger without it

And yes, Ford Dealer would have no way to delete PATS, they can't even change the HEC cluster last I heard, they have to order a new HEC cluster in with preset odometer matching PCM, and then they can swap it out and re-marry them, and also program in the PATS keys the customer was using with the old HEC cluster

An Alarm system was an option, i.e. horn honks and lights flash
PATS is Passive Anti-Theft System, no horns and no lights, just No Start

An alarm is an active theft system, might have motion sensors and door open sensors that sound horn and flash lights, and it can easily be called an anti-theft system same as PATS although they are much different

Although a thief can drive away in a vehicle with horn honking and lights flashing, lol, so not really anti-theft, more theft deterrent, while PATS is anti-theft, but not anti-break in and steal stuff from inside cab, lol.


Marrying allows HEC and PCM to "talk" so not related to PATS, except for the fact that the HEC must "tell" PCM its "OK to Start" engine, after HEC qualifies the correct PATS key is in the ignition cylinder

 

well djfllmn, per the attached picture, and the red underlines; according the the ford workshop manual, it was not standard. though surely, revisions to documentation couldve been possible. i however special ordered the truck through fleet and received it middle of 2006.

 

Ron, I see. well i will talk to skyline ford about parts availability on this. cost is my own problem. or find them at the local wreck yard.

 

As far as I know only 1998 Rangers had PATS as an option, so book is wrong

Here is the 2007 Ranger brochure: http://assets.forddirect.fordvehicle...A8E966D4A8.pdf

SecuriLock is PATS trademark name and it is listed as Standard feature on all models

Page 9 under safety/security

I did look up the 2006 brochure as well and it is different
SecuriLock® passive anti-theft ignition system (3.0L and 4.0L V6 only)
So could have been optional on 2.3l 4cyl, maybe thats what book is referring to?

2006 brochure here: http://www.auto-brochures.com/makes/...anger_2006.pdf

 

thank you ron for the brochures. i have a different looking 2007, but it shows the same things in it. the book wasnt referring to the 1998 model year, but 2007.

the book isnt specific on one engine type. it covers all three, of 2.3, 3 and 4 liters. as well as different options such as air conditioning, speed control, fog lights and rear fender steps. there may have been revisions to the workshop manual since publication but mine shows that passive anti theft system was available with and without for the 2007 ranger. --per the name on the cover of 2007 ford ranger.
