First of all nice to meet you ( as I'm new to forum ) and sorry for my english ( not a native speaker ).
My problem appeared 6 months ago. I was just found out about the car self test, I unlocked the car
using the remote entered the self test, looked around there, exit the car, tried to lock it using the remote,
but was not working anymore. If I lock placing key in the door, central locking is working fine. I have a normal 3 button
key with remote on it.
What I tried:
First thing I checked the battery and change it. also cleaned all contacts in there, tried to reprogram the key, no luck. I tried several times,
after the procedure ( 0-II 4 times), I don't hear any sound to confirm entering learning mode.
Second I checked fuses, no fuse regarding central locking was damaged. checked all fuses (gem + motor) nothing wrong here.
I went to be checked by a mechanic, he had a diesel from 2006, he changed his key with mine and tried to program his key
on my car, no luck ( no learning mode ). he also checked fuses.., then he changed his gem with mine and tried with my key
to reprogram it ( but no luck here either, no learning mode ). He said to come another day.. when he has more time ... to check
the wires then I called him, no answer or to call him another day, I gave up on him. Forgot to tell he made also a electronic diagnose
(I think that's how is called) but no errors regarding my key fob.
Finally I went to a local ford dealer, telling that lady on the phone, that I can't reprogram my key. After 2 hours of tests and whatever
they did there, they gave my car back saying that the car is not entering learning mode and to come another day if I want, because
needs reprogramming ( I don't know about what was talking here) and they need to check all wires, but it costs alot and is not worth it...
said that guy. They also did an electronic diagnose, which shows no error.
One last thing I tried last few days, I've read about the "service mode" and how sometimes this does not exit how it should and some
car functions are not working ( I was not doing that when stopped working but I said to give it a try) so I saw an reset service mode and tried that, it enters
that procedure, I hear the sound, I followed the procedure but I don't hear the 3 beep at the end of the procedure, when key pos is at 0.
so I think the reset is not done as it should(tried a few times also) ...
I don't have any other electrical problem, just a thing which I'm not sure of, when I have the switch on headlamp and you open the door with no ignition key should
beep right? I think this stopped working at the same time. All other sounds work fine ( door open ... ). As a conclusion I have no
sound when key is at 0 position
Car is a focus petrol 1,6 ti-vct, build date 12.2004, mk2
Can someone have any ideea on what might be wrong,
an electrical scheme would be nice (just saw the all wiring is here), where is positioned the remote receiver for this car, in GEM or ?
Sorry for the long post, hope that someone can give an advice because I'm tired and frustrated on finding the problem.
