hii all, i have a ford focus 1.6 tdci mk2 on a 2010 plate, the car had a under dash fire and previous owner changed the wiring loom, ecu, key and ignition barrel

the issue is ... the immobilizer light is flashing when ignition is on, car is not communicating with diagnostic scanners. the car does not turn over at all, and displays the following on the lcd display
'Transmission Failure' ( the car is manual)

we've checked all fuses, relays and wiring plugs with no issues to report..

just wondering if anyone on here can help me solve the problem...


thanks in advanced

so, 2010 car, and it had a fire under the dash, but only the one wiring loom was replaced?

Sounds to me like there is more wire damage within, or possibly component damage to the rear of the dash sending a few duff signals...

How did the fire occur? whilst the car was moving? whilst asleep? I would be concerned that if the car was in use at the time, that a power surge / excessive heat melted the wires causing the fire, but that damage most likely would have spread to the likes of the fuseboard / other relays causing untold damage...

Methinks it is knacked.
It is dead, bereft of life, it rests in peace, It is an ex car.
Sorry, another long busy night shift. <_<

Totally agree, someone did a shoddy repair job on the wires.
Probably got melted insulation and carboned earth points all over the place.
I'd also reckon that the ECU is buggered too.

im nt quite sure how the fire started however everything under the dash has been replaced, ecu and all the start gear was replaced, everything else seems to be working, i.e. headunit , lights, heaters ive checked the fuse box, everything electrical and all seems fine

sorry i cant really offer any advice, but surely if it is 2010 plate it would still be under warrenty? can you not just take it in to ford??
Or is the service history not complete?

There must be more to it than just the ECU , there are other parts i'm sure that all need to sync With the ECU before it will start ,has it been into Ford For the ECU to be set to the Car

hi really appreciate the advice but i think the issue needs some clarification.

after the fire the car has had the following items from a donor vehicle

ecu
transponder
key
ignition set up
fuse box
wiring loom
and the clocks


everything else on the car works fine, all the lights inside and out, central locking, windows, radio etc all work

so i am pretty lost as to why the car still refuses to start, its as if the immobilizer is switched on and not turning off

Do you know if the car was exact same model? , I'm still sure its not as easy as just a straight swap of parts.
Also the Immob would need to be set to the key wouldn't it ?


just posing a few questions that might trigger an idea

yes the parts were taken from the same model focus, as far as i am aware the key doesn't need programming as the ecu, immobilizer, clocks, transponder, ignition barrel all came from the running donor car

surely if you disconnect the ecu system, when re-installing would you not need to program it all in again evan if your putting back in the same car?? sort of like a computer, are you sure its not been restored to factory settings so to speak??
it might just be a case of popping into ford and getting them to programe it???
again just an idea

I'd reckon the ECU and PATS2 units need recoding.
Are the keys the originals or from the donor car?
Sounds like the immobiliser
Isn't recognising the transponder chip in the key.

The PATS2 receiver is a ring around the ignition barrel. As to the immobiliser unit I'm not totally sure.
Someone here will know for sure.
