PATS problem


Carl160180

Recommended Posts

Right as some of you may know I bought a T reg escort flight off e-bay, the car had no keys as the keys had been lost by the previous owner. Now I got a full lock set, steering column and ecu off a mate of mine who was breaking a P reg 1.6 si, plugged the ecu in and fitted the steering colum with new lock etc and the pats light is still flashing as if it's not getting the right code from the key. I have the 3 keys from the si, red key and 2 black and neither of them work ?( ?( The only thing I can think of is either the pats module need's fitting from the p reg si or that there's something else that i've overlooked? I'm not 100% about the pats module being the cause as I thought the coded bit for the pats was built into the ecu but obviously there's something not right LOL

 

Anyone have any idea or had a similar problem? Need to get this car running asap!

 

Thanks in advance

... and the pats light is still flashing as if it's not getting the right code from the key.

 

The pats light should flash rapidly for 30 seconds and then flash a fault code.

 

 

Any idea where i'd findout the fault code's? will autodata tell me?

 

STU - The only difference I? noticed was with the pats transponder round the ignition lock, the original one is part of the harness and goes right up behind the dash, the one off the Si unplug's just under the steering column. But seeing as this is just a reciever then i'd have thought that it would'nt matter??

you may need to check,

 

-the ecu wiring diagrams (that the pats circuit are all in the same pins)

-the transceiver is the right one for that ecu (there are different part numbers and they dont all work on every escort)

-the cable between the ecu and transceiver may affect it.

 

 

your best bet is to check the transceiver cable compared to the car the ecu came from and replace with that one it if its different, if its the same, take the transciever from the other escort and plug it in. either way take that transceiver.

 

so long as the keys you have were originally with that ecu you should be good, otherwise you need the locksmith to reprogram it

I take it by the transceiver you mean the bit round the ignition barrel that reads the key?

I've posted these on this forum several times, but if you get a code and post it here I'll tell you the meaning.

 

Cheers mate, I'll give it a look tomorrow and see what code it blinks up ;)

Never had a chance to check the blink codes yet but can anyone tell me what part the transceiver is?

Right well the transceiver that I got out of the p reg si along with the ecu and lockset is slightly different to the one currently in the car as in the original one the loom unplug's out of the actual transceiver, the one out of the p reg si, the transceiver has the loom fixed into it and about 12" down the loom there's a plug to unplug it, the current setup I have is:

 

P reg Si ecu

P reg Si lockset

P reg Si keys (1 red 2 black)

T reg flight transceiver

 

I can't see any other way of using the p reg transceiver unless I trace the loom all the way down to wherever it goes and splice the P reg si transceiver into it????

 

Either that or splice the original wiring into the 12" of loom off the si transceiver????

 

Can't the pats be bypassed at the ecu plug? IIRC when changing the pins for a 2.0 conversion you have to cut one pats wire and tape it out the way and earth another and it works?????

the PATS can DEFINATELY be bypassed...by fitting a non pats ECU, from an old mondeo..and doing the 2.0 wiring conversion

 

I done it on my old Si which was a 1.6,i fitted a 1.8 engine and used an old mondie 1.8 ECU to run it, worked a treat.

 

There is..somewhere..a list of ECU names,and the spec of them and it tells you which fords had what ECU codes and weather they had internal pats or not...I know BLOB is a 1.8 non pats,and obviously u have the 2.0 non pats ones DEEP,DESK,etc..unsure what 1.6 one u'd have to find...dont see many 1.6 mondeos though

OOPS, Wrong account LOL

 

Right bit of an update on this, Me and my mate have just carefully removed (axe and a big hammer) the dash out of the donor car and is has'nt got the pats module behind the dash, the wire's from the transponder round the ignition barrel go all the way to the ecu plug :(

 

Look's like a non pats mondy ecu is in order unless someone has a later model ecu and key from say an S or T reg 1.6 they wanna sell?
