What does this ecu do?? - bashbarnard - 27-05-2014
As title not really sure what this does. Its on a dturbo and if you remove the centre console there is a sectuon that can be pulled down to get access to this. [attachment=16478]

Its the immobiliser box I think. At least that's where the BSi is on the ph3s.
RE: What does this ecu do?? - bashbarnard - 27-05-2014
Well it started witout it connected? I thought that. Any other ideas?
RE: What does this ecu do?? - Toms306 - 27-05-2014
Oh right, umm, maybe its been disabled/bypassed? Can't think what else it'd be for tbh. Does the central locking still work with it unplugged?
RE: What does this ecu do?? - bashbarnard - 27-05-2014
Ah I didnt try the central locking. I will venture in rhere again when I replace centre console and try
RE: What does this ecu do?? - vincent1 - 27-05-2014
its the alarm ecu.
RE: What does this ecu do?? - welshpug - 27-05-2014
phase 1-2 transponder unit, separate to the alarm control unit and CL relays.
your coded solenoid has probably been bypassed/replaced with a standard unit.
phase 3 has integrated alarm transponder and CL unit, NOT a BSI.

is it not the airbag ecu?
RE: What does this ecu do?? - bashbarnard - 27-05-2014
Ah I see so probally central locking related and fob related. I dont have a fob. Just standard. Also I know my immobiliser works because I unplugged the exciter and it wouldnt start. (I was in the area)
RE: What does this ecu do?? - welshpug - 27-05-2014
what exciter?
RE: What does this ecu do?? - bashbarnard - 27-05-2014
The reciver then. The ring round the ignition barrel.

Are they not body systems then?
And what would you call it for short, that's a bit of a mouthful.
RE: What does this ecu do?? - welshpug - 27-05-2014
Peugeot call it alarm ecu iirc, bsi is a multiplex thing, 306 never was multiplex
RE: What does this ecu do?? - Toms306 - 27-05-2014
I'm sure it still comes up as BSI on PP2K, built in systems interface 'Texton' iirc.
But fair enough. Everyone still knows what it is if referring to it as a BSI though lol.

It's the ACU alarm control unit. If your central locking don't work then it probably does nothing. I cut into the wires to fit my hawk central locking kit. Worked a treat
RE: What does this ecu do?? - bashbarnard - 01-06-2014
My central locking works but I thought that was under the rear seat? Or is that just an phase 1s?
RE: What does this ecu do?? - HD-Aye! - 02-06-2014
Not sure then, mine is a ph3
