Tried to get into my 97 Griffen on Wednesday but the remote keyfob was unable to disarm the alarm so immobiliser wouldn't allow the car to start and the horn woke up the neighbours.

Thought it might be the batteries in the keyfob so got new ones fitted. Still no joy (from both keyfobs).

As it stands at the moment, I am unable to use the car. Are there any procedures to check alarm function?

It's the standard alarm that the car came with. One keyfob button arms / disarms and the other operates the boot release.

Any help would be appreciated as I am unable to switch off the alarm / immobiliser.

The key activates the central locking fine but does not turn off the alarm or the immobiliser.

I have the battery out of the car now to do an overnight charge just in case

Can anyone else help - took the battery out overnight and charged - still no difference.

The HAYNES manual has nothing on the alarm at all. Don't know what it looks like or where it is.

It seems that the fobs are working correctly but the receiver on the alarm has stopped functioning.

Does anyone have any links at all to useful info?

Alarm

Try the tech help listings, they might have something. There is an alarm actuator in the drivers door that is supposed to arm or dis-arm the alarm when you use the key and the remote. On my Oldsmobile, sometimes the locking and alarm unit is fooled (or jammed) by RF signals given off by power transformers or heavy elec equipment. But the key always disarms the alarm. Since your key does not disarm the system, I'll bet the problem is with the door actuator or the central unit... where ever that is! Unfortunately this sounds like a dealer or specialist problem though.

Main dealer reckons it's the ECU guys.

Needs a new one - their price has left me reeling.

Anyone any suggestions?

Does the 9000 just have one ECU - is it easy to replace with a 2nd hand part?

there are two types of saab alarm on the 9000 :roll:

the first is the type that only imoblizes the engine when the alarm is activated

the second is the type that imoblizes a few seconds after removing the key irespective of whether the alarm is active or not, this is called alarm with VSS, vehicle securaty system.

the are not interchangeable

Well, definitely have VSS thats for sure. But the alarm is part of the ecu is that right - it's not a seperate part of the car i.e another ecu.

Reason I am asking was I was just thinking about buying a MAPTUN stage 1 ecu and that would soplve my problem wouldn't it?

the alarm is a seperate ecu and it is fitted behind the gove box and riveted to the back of the dash, but if you have VSS then the engine ecu also has the imobalization (sp?) built in, my worry is, if the alarm is sounding when you enter the car it must be working so how has the dealer came to the conclusion that the ecu is at fault as there are lots of things to test before condeming the ecu, like the alarm arial , again 2 types one in the rear veiw mirror or the other is a bi wire antener in the roof under the cover for the elec' roof motor

In my instruction book, it mentions that if the remote alarm/immobiliser won't respond, you push the unlock button five times - or something like that?!?
