Hi, looking for some help as during this lockdown decided to take wraps off long stored 2+2. The Texalarm which I believe to be aftermarket on this 1.8 turbo diesel will notfunction; there appears to be a receiver unit in the central console and a tell-tale LED on the righthand side of the upper dash.With battery charged this LED is lit but does not react to fob.Any help/advice on how to address or by-pass would be much appreciated.Regards

Firstly a silly question, have you checked the battery in the remote isn't
flat, there is a led on the remote but it will still flash even if there's
not enough power in it to send a signal.

I seem to remember the texalarm on my 2+2 stop responding to the remote a
couple of times.
On mine there is a reset button in a hole in the side of the main control
box that you can press with a paperclip, i think it will then recode it to
the remote when you press it.

Somewhere i do have the instructions for it still but Quantum did use a
couple of different version of the Texalarm.

To bypass it you will just need to trace the wires back from the control
unit into the loom, these are probably all black wires.
Most of the wires will just tap into existing circuits without breaking them
but in 1 or 2 places you should find the original Ford wire has been cut and
there are wires to the alarm from each side.
You will need to rejoin the original cut wires to bypass the immobiliser.

On a petrol engine these usually break the ignition coil circuit and the
starter circuit, on a Diesel it is probably the fuel cutoff solenoid and the
starter.

If it's been done properly the cut wires will be behind the dash and the
ends won't be adjacent (i.e a section of the original wire is missing) but
this is rarely done and usually the wires are cut on the steering column
(especially for the starter) or near the ignition coil / fuel cutoff
solenoid .

Thanks for that Jim, I assume the main control unit is the Black box in the central console? I did renew battery in remote and it did once get all the lights flashing which I thought was promising but false dawn unfortunately. Will try reset and some wire tracing. Is the dash light just an awareness raiser for thieves? Regards Dave Robinson

Assuming it’s fairly big, maybe 150 x 100 x 40mm then, yes, thats the main box for the alarm.
The hazards should flash on arm / disarm.
The dash light should go out when the alarm is disabled but it will auto rearm after a min or so  unless you turn the ignition on.

Thanks again Jim, I found the control under the glove box, and as you said there were lots of black wires into a black plug and multi-coloured into a white plug. When purchased in 2003 I got loads of paperwork and suddenly remembered that previous owner from new used to holiday in France and couldn't start it over there: true to form I found both and English and French version of how to by-pass the Texalarm, only problem, they used coloured wires where mine are all black so spent day identifying pin A1 and A2 to bridge and also A3 and A5 to do likewise. Success the alarm is cut out and engine turns. Just need to check other bits before flushing and seeing if it will start. Once again thanks for assistance, much appreciated.

Does anyone know if replacement remotes are available for Texalarm. One of mine won't activate locking etc. The led on the remote lights up but appears to stay on for about twice as long as the led on the working one. Battery is definitely not the issue.
