PATS problem

Rate this topic


Recommended Posts

This is on the family windstar.. 01 windstar just yesterday the theft light flashes rapidly indicating non programed key/incorrect key for both oem orig keys. It does all the correct things ie. will not start-crank with either key. It will start with the remote start no probs the theft light comes on solid engine cranks and starts light goes out, it has a transmitter glued to the transponder to simulate a chipped key, insert any key and away we go.. I have reprogram the keys "successfully" according to the ids but then the theft light flashes rapidly again right after. scanned all modules and got...

U1262 IC SCP communication fault

B1342 pats ????

B1602 pats incorrect key code

Ran self test on IC and get u1262

pcm P1000 and B1602 incorrect key

according to wsm b1342 indicate "replace pcm" no diag needed!! If there was a prob there it shouldn't start with the remote start should it? That is the part that send me for a loop.. I have limited access to the ids to perform the ppt M No communication on scp network where they want you to disconnect each module to see what one is not communicating... I do think it might be a pcm issue as the koeo self test failed a couple times then worked ok.. Any one have any insight or pointers to this concern?

We see these kinds of problems once in a while at my dealer on vehicles that have remote start.

If you have a programmed pats chip glued to the transceiver you shouldn't need to program any keys because the van will think it always has a programmed key in the ignition. The action of going into programming mode may have erased the "glued on" chip from the system, and then when you went to program a key it saw 2 chips (the glued one and the one in your key) and didn't know which to program. I would remove the glued on one and start the programming all over again.

As far as why It starts with the remote start (assuming what I said is right about the glued on chip being erased), well that's confusing to me too. I know some pats systems inhibit the starter relay and some will crank but prevent the injectors from firing. If your Windstar has the crank inhibit style, perhaps the way the remote start is wired defeats that feature regardless of whether there is a programmed key.

 

I'll have to do some research on this one.

There is no chip glued to the transceiver, it is a disk wired to the remote start module that only operates when the remote start in commanded to start.. otherwise it should start without a chipped key and no more pats to worry about and thus rendering pats totally useless as an anti theft system. Like i said it will only start with the remote start. the theft light comes on solid it cranks and starts then goes out like a properly functioning key would. both keys will go straight to theft light blinking rapidly and will not crank indicating a key not being read correctly or at all... I am going to try and pull the tumbler and place a key on the transceiver and see what happens.. can the transceiver loose it's strength to read the key being further away then the R.S. disk?

What happens if you unplug the PATS module from the remote start module, then try programming the keys? Maybe the remote start module is constantly powering up the remote start/pats interface causing your interference?

 

Or try peeling that disc off the transceiver to see if something's interfering with the signal from the key.

 

When you are programming the keys, are you using the "add a key" in the IDS, or are you deleting all programmed keys and programming two new keys?

I am reminded of a classroom scenario... 98 Windstar - no start - theft light flashing with, IIRC, an open fuse being the culprit...

 

Are your codes memory codes or On Demand codes? If you clear them, do they come back quickly or take a while?

 

Have you tried unlocking the doors using one or both fobs?

Aaron, I think the easiest way to try that theory is to use a reg non chipped key, with out 2 signals it might work, if it starts then the r.s is the cause... I dont want to disable the only reliable way to start the van at the moment. I was trying to just add 2 keys not delete all then start from scratch but that is an option to try.

Jim, I will check ALL the fuses.. The b1602 is always there can't clear it because the theft light will always flash with the key in the run position. b1342 only showed once in cmdtc and u1262 koeo on-demand 3 of the 5 times I ran the test but it has not liked any of the keys in 4 days.. I will be getting into this more on monday if i get my foot out of this cast!!!

Cheers

Way to go Aaron!! I just removed the tumbler and used a modified screw driver to try it without the key present and what do you know it started right up!!! Put the tumbler back in and got the rapidly flashing theft light instantly.. I tried several times and each time was the same. so it will go back to the place that installed the remote start for warranty!!! Now some one else can loose their shirt on warranty diag!!
