Yes, that's the one - far too new for a Synergie Gibbo - but at least you found it - time for an ebay session me thinks

If anyone wants it they can have it free gratis Marc it's just another bit of stuff taking up space, very little space.

That picture is an alarm ECU not a CPH. The CPH is about double the size & has 2 bigger connectors.

The OP started to talk about the Texton alarm, which kicked this side topic off.

Is there a list of dashboard codes available? When pressing the the rest button upon ignition a bunch of codes come up, 101, 14161 and 001.
I`m trying to find someone who can bypass the immobiliser as I appear to have a fault no one has ever heard of.

The immobiliser is built into the BSI and engine ECU and is not a separate hardware or software function.

The bits I have highlighted below make me think that you have a wiring fault, or a corroded connector or a hardware fault in one of the fuse boxes or ECUs.

Ok. I have checked and tested all fuses and they are fine, I have tried the resynchronising method but no difference.
I will say that have noticed the Fuel Pump relay under the bonnet is going into `spasm` buzzing, changing it made no difference and the security LED on the dash near the windscreen is still dim and does not flash as it should. The engine turns over fine.
I have been told there are different OBD II testers eg EDC15-EDC17 Read Write MPPS V16 ECU etc, what is the correct one?
Thanks

In the absence of a wiring diagram for this vehicle, I think that you should find a wiring diagram of something with the same engine type and use that to trace the voltages for the security LED and the fuel pump relays back to the respective ECUs to find out where the voltage is disappearing. I think that you will likely find that one of the fuse boxes is faulty.

FIXED FIXED FIXED FIXED
After 3 months of digging around the net and talking to numerous garages and auto electricians I found the cure.
I was recommended to a company called ECU Technolgies Ltd in Staffordshire details below. For £102= inc return postage they were able to decode the ECU, this means it does`nt need to communicate with the Texton immobiliser which is now removed.
I do need to fit a different central locking system as this was part of the immobiliser, everything else has been working fine and the car has now been saved from the scrapyard, its in stunning condition so worth saving.
I just need a heated rear window as it was vandalised after sitting outside the house for so long, if anyone can help with that?
Thamks for all the input from all who replied.
