Carl160180 Posted November 18, 2008 Share Posted November 18, 2008 (edited) 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 Carl Edited November 18, 2008 by Carl160180 Link to comment Share on other sites More sharing options...
Stu Posted November 18, 2008 Share Posted November 18, 2008 What are the codes from both ECU's? Link to comment Share on other sites More sharing options...
Carl160180 Posted November 18, 2008 Author Share Posted November 18, 2008 (edited) The original ecu was WISH and the replacment is TUNA. Both car's are a 1.6 zetec but the p reg si had the cast alu inlet, not sure if that makes a difference??

Stu Posted November 18, 2008 Share Posted November 18, 2008 I'd have to compare wiring diagrams between them. It's possible they run different PATS transceivers.. Link to comment Share on other sites More sharing options...
SteveB Posted November 18, 2008 Share Posted November 18, 2008 ... 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. Link to comment Share on other sites More sharing options...

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?? Link to comment Share on other sites More sharing options...
onehotminute_191 Posted November 18, 2008 Share Posted November 18, 2008 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 Link to comment Share on other sites More sharing options...

onehotminute_191 Posted November 20, 2008 Share Posted November 20, 2008 Never had a chance to check the blink codes yet but can anyone tell me what part the transceiver is? the plastic bit that goes round the barrel has a bit of loom coming out of it too Link to comment Share on other sites More sharing options...
Carl160180 Posted November 20, 2008 Author Share Posted November 20, 2008 (edited) 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 ecuP reg Si locksetP 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?????

Craig855S Posted November 21, 2008 Share Posted November 21, 2008 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 Link to comment Share on other sites More sharing options...
zetec Posted November 23, 2008 Share Posted November 23, 2008 Well i'm gonna try swapping the main pats module from behind the dash with the one out of the donor si, If that don't work i'll be on the hunt for a 1.6 mondeo non pats ecu! Link to comment Share on other sites More sharing options...
Carl160180 Posted November 23, 2008 Author Share Posted November 23, 2008 (edited) 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?
