My alarm (factory fitted 2006 Previa) would keep going off randomly - problem was getting more frequent. Checked all the door switches and bonnet (easy) and boot (harder - you have to remove all the trim 1st!)
Found out how to disable the interior pressure sensor - which solved the problem:
'Single' lock the car (1 press on key fob = 1 flash), then double-lock the car (2nd press on key fob = 1 flash) then press and hold the lock button on the keyfob for a 3rd time - this time the direction indicators come on and stay on for a couple of seconds. Now the alarm is set but the interior sensors are disabled - it would still go off if you open the bonnet/door etc. but there are no more false alarms!
As an alternative you can completely disable the alarm (so it then won't go off when you open the bonnet/doors either) by leaving the bonnet open when you lock the car.
So to do this permanently, remove the bonnet switch from its bracket and lay it down out of the way in the engine compartment, then the alarm thinks the bonnet is (always) open when you look the car so the alarm won't arm!
To remove the bonnet switch, 1st remove the connector to it then you have to squeeze the two lugs holding the switch in its bracket so that the switch can come up through the bracket. Once its out you simply reconnect the connector and leave it laying down. (Or you could unbolt the bracket itself as then you can see more clearly what you have to do!!)
On the two places I've got on fuse box schematics it did not cover that year / model . But on both , the alarm set up on earlier cars was covered by more than one fuse and had other circuits intergrated which scrubbed pulling them .
Yes kept hitting a brick wall ' just no information anywhere not in the book either nothing on the alarm and in the fuse box theres nothing about alarm " nothing on wiring diagram in the book. Theres a flashing light on the dash and a large one by the steering wheel ' if i use the car at least every two days its fine leave it for four "" flat battery brand new battery " exactly the same as the old battery every four days totally flat ' might take it to an auto electrician see what he thinks ? Hate bloody cars lol
