yes I have waited for as long as 1 minut before trying to set it off and still nothing happens. I hoped it was only the indicator light that had a problem but it's the whole security system at the doors, my bose radio have the anti theft light on(flashing) when I turn it off but the indicator in the door and the alarm itself doesn't work.
I'm pretty sure I've seen it flash when I first picked up the car when it arrived in Denmark but I'm not completely sure about that and I'm thinking maybe the previous owner had disconnected the stock alarm but hmmm..... I don't know.
I think the easiest test would be to swap out the alarm control unit(if you have one available). The alarm unit is located under the drivers side dash in the usdm models(should basically be the same), use the online manual(the link a gave you before) to assist you in finding and removing this part.
If it's not the unit It could be something as simple as a lose wire going to the system or a bad "arming switch" such as the one for the hood, trunk, or doors. Normally our alarms will not arm unless everything is closed, so if the system thinks something is still open, due to a bad switch, it will not arm. Good luck
