PATS (Passive Anti Theft System) thatcham CAT2 aproved immobaliser

Non PATS
before pats was introduced in 1992 there were zetecs built without pats but only 1.8s and maybe some 1.6s however i know of no non pats 2.0 ecus
Prior to the installation of pats ford could be hotwired very easily or the ignition could be forced etc

External PATS
pats was introduced in 1992 as "external pats" where the pats system was seperate from the ecu and as such you could change the ecus and the pats was unaffected. external pats ecus take a signal from the pats module to say the chipped keys are present and it will then start the car. this can easily be bypassed with a live feed to the pats trigger on the ecu, this made the cars harder to steal, even now most amatuer thieves would be stopped by external pats

Internal PATS
around 1995 ford changed the pats system to "internal pats" which as the name suggests the pats system was incorporated inside the ecu and changing ecu is a ball ache involving swapping keys or chips and the pats sensor etc.

good to know. what made you write this up then?

also, would the 2litre ecu be refered to as non-pats, or external pats, because wouldnt external technicaly also mean not incorporated in the ecu? is that winding you up lol?

its external pats the 2.0s (desk deep dewy)
and it does have pats as if you plug an external pats ecu in a non pats car or visa-versa it won't run

Stuff went to internal PATS late 93. Depends on the car though.

I can only assume that the pre pats term came about to refer to an ECU that didn't have internal pats fitted as they came later. It's come from somewhere and it does make some sense, not as much as being being specific obviously.

I have a mk5b 1.6si, and I'm pretty sure that's external pats, im doing an engine swap to a 1.8 130, and have a 1.8 130 ECU from an early mk6, and a 2.0 mondeo ecu from a 1998 model, both with keys. I also have external edis on mine. Am I right in saying im going to have to rewire the whole system to run either of the later ecu's?

Whats the code on the 130 ecu as there was no mk6 130.

For the mondeo ecu yes you will have to change the pins. Pre pats ecu's r a million times easier to work with though

If yours is a mk5b and your struggling with the ecu's, i have a mk5b 130 ecu here with key and transponder which would plug in without any wirin alterations

Ever noticed that putting "anal" in front of some ford model names makes them sound funny? Fiesta, Probe, Ranger. Explorer, Maverick etc... lol

It's a cast ecu, it came from a 1995 very early mk6, they did do a 130 mk6 but only for the first year, my current ECU for the 1.6 is envy, and not sure about the mondeo one. What you want for yours mate?
