My RAV (4.4, 2014) decided to use the alarm lately. Problem is that it seem to be intermittent, and with no apparent reason. I did discover a dead bee after it happen, but it also occurred afterwards, so not sure this was the cause.
Going to the MrT to complain will not be good, as it does not happen regularly (car is under warranty).
Does anyone know if the system keeps a log of why the alarm was triggered? (ie which sensor caused it to trigger)
If it does (and I'm doubtful and it most likely will just store the last trigger event only), I'd wager it'll be stored in the body control ECU, which usually won't be readable with the cheaper powertrain only E-OBD readers.
Do the usual and check the condition of all the door switches (and don't forget the bonnet switch).
The 4.3 has the interior movement sensor up behind the front cabin light fixture and I'm fairly certain the 4.4 is the same. The 4.2 has a sensitivity adjustment for this (and the sensor was behind the dash), but I doubt the 4.4 has an adjustment (fairly certain the 4.3 doesn't). 4.2 systems were effectively "aftermarket" and fit at import, which is probably why the adjustment was present. Everything since has been related to the body ecu and is factory fit.
Check there's nothing that can swing around slightly in the cabin if the car gets rocked in the wind.
....and I can't remember whether the 4.4 has an interior sensor disable switch like the 4.3 has, to do the usual "disable and wait for the fault", just to eliminate that............
Failing that, spend a few euros on www.toyota-tech.eu/ to spend an hour there. The repair manual sometimes has usable pointers to such things. I don't have all the 4.4 info from there, otherwise I'd look through it for you for pointers to potential faults.
Many thanks shcm! The 4.4 does have an internal sensor and can be disabled, i will try this. I have checked the doors sensors - they seem to work ok, but I do not think there is one for the bonnet, as the 'door' light does not come on when it is open, and i could not locate one. The day before it happened twice, and since then the car is locked and it did not occure. Shall wait and see.
I'm reasonably certain there will be a bonnet switch. Do you not get a bonnet open message with your vintage of the 4.4? I'll have a look @ mine later. It's probably similar.
I'd expect it around by the bonnet latch somewhere. Anyway, a good way of finding out is, pop the bonnet, but leave it latched. Often that won't open the switch. Lock, set the alarm, then lift the bonnet and usually the alarm will go off. I've checked bonnet switches this way in the past (both deliberate and non-deliberate!).
Tried that... No, there is no alarm on the bonnet. It can be fully open, and i can lock the car with it fully open as well. I would have expected from that kind of car to have one, but no. Also no switch either by the catch or the hinges. Will be interesting to know if that was changed in later versions. I kind of hope it was some insect inside the car, and it perished in the extreme heat yesterday. I will keep an eye.
