Ive a Vectra C 2.2 direct 2006 Estate.Also Its the facelift 2006 Vectra Estate which I dont think has a backup battery for the Power Sounder?? Does anyone know if its got a built it battery???????????
Hoping someone can help, Parked the car up on the drive and locked up as usual, 10-15 mins later the alarm goes off. Reset and all ok another random time interval and goes off again. Keeps doing this..
Put the op-com on and got :-
B3901 - Wrong Environment Identifier Received
(00) - Not present
B3078 - Anti Theft Warning System Ultrasonic Sensor Circuit Malfunction
(05) - Present
I've checked the Window Pane sensors which are ok, also op-com says Okay too, (I couldnt find anything on the rear window does anyone know if there is a window break sensor there? maybe it runs through the main demister element?? )
Bonnet sensor is saying closed, and I've disabled the ultrasonics (By pressing the button on the dash before leaving).
Still the alarm keeps going off (it could be 10 mins or 2 hours) at random intervals
Its starting to get a bit of a pain not only with me, but the neighbours too! Starting to think its some kind of voltage fluctuation but dont know where to start 1st????
Any help would be appreciated.
