Going on from the pre-facelift/facelift alarm adaptation...

If the alarm goes off, regardless of key in ignition, is it a case of reseting it / reading the codes woth Tech2 to see whats what??

I can't for the life of me stop this damned thing sounding, key in ignition, doesn't turn off, lights keep going.

The car has 'no' powersounder connected, that got jibbed off ages ago.

*note*

The alarm only started going off when I plugged it into the car 'before' i did the wiring changes.  I locked the car, unlocked it and then it started to go off.

Before I locked the car, all was silent.  Now, its always on the second its connected up, regardless of locking/unlocking the car.

Ultrasonics are *not* connected (not got them yet) so pins 5, 7 and 12 from the control module are not connected.

Thats what I was thinking, but word from the tech2 wizards in the other thread said no tech2ing would be needed...

The floaty wires are all taped up so not grounding or shorting anywhere...

Ahh, but electrically they're floating (i.e. inputs not driven by anything). If, for example, they trigger the alarm when a "high" level is present and they don't have pull-downs inside the alarm ECU they could be triggering the alarm. I'd be inclined to get a test 2 or cheapo on it and read the codes. IIRC cheapo can read alarm codes.

I would say the time delay relay input  probably disables the voltage drop detection until the time delay relay has switched off the cigar lighter socket. This can probably be tied to either +12v or 0v - whatever state it's in when the relay is off.

Actually...

I could do with knowing the state of Pin 4 (black wire) frm the 28pin connector during ignition off, doors locked, and ignition on / engine running...

if someone with a facelift has some time spare to tinker with there's, and a multimeter of sorts

Cheers Kevin

So CSR then should be the same as TKS, which is the door closure switch on the pre-facelift, but 'could' be outputting a different signal, or is delayed as you say so so need to check into that one too... might just end up pulling 12v as you say to prevent it triggering...  I'll see what the signal is though when the doors are shut and when there open, just incase its sending something else!

I'll feed down an ignition live from somewhere for pin 4 too, either from the lighter socket or somewhere else...

Already fathomed out the ultrasonics though, have those 3 wires isolated at present, but pin 11 on the 12-way is connected (grounding signal for the sonics relay) as they are both the same on pre-face and facelift.  Just need the wiring from kickpanel up inc. sensors and im good with that one!

Pin 23 is same on the pre-facelift too, so signals should be the same.  If not, something else to look into...

Nope, already looked into that, the alarm and immobiliser ar not paired.
