add on alarm and remote start problem

OK, i'm going to try and explain this without boring the hell out of everybody. I just bought a 2009 toyota camry and had the dealer put in the add on alarm and renote start. They used Pursuit (audiovox) alarm model PRO 9233 and Pursuit remote start model PRO9051. The problem I'm having is if the remote start either runs its complete time or if its turned off manually it triggers the alarm. Basically whats happening is on the factory toyota system, when you turn off the ignition the dome light goes on and thats what is triggering the alarm. The alarm module only has a shunt for the trunk and NOT the door trigger. Is there some type of fix for this or can i create a shunt myself? Thanks

how long does the dome light stay on?

Approx. 3 mins. if the door is not open and then shut again.

well you had the dealer install it, bring it back to them and tell them the store where they installed it. the shop if reputable will fix it free of charge.

ok thats a little long, longer than i thought. at any rate, what needs to be done is the factory door trigger wire in the car needs to have a diode installed on the door pin wire with the white band facing toward  the door. then the door trigger wire to the alarm will have to be connected somewhere on the door pin wire between the door side and diode so that the negative voltage will still flow from the door pin to the alarm but be blocked from bleeding back to that wire off the OEM side. the door triggers should already be installed at each door and diode isolated, so its just a matter of adding in the extra diodes on each factory door pin wire to block off the BCM signal.

Chances are they used the brown domelight wire as the door trigger, there's nothing wrong with that. The problem here is that just won't work in this case. As ckeeler stated, what needs to be done is grab 4 individual door triggers and diode isolate them then use that as door trigger. This will stop the dome light from triggering the alarm. The 4 triggers can be found on the BECU behind the drivers knee bolster...Mike M2

yes but not only that Mike, the OE door pin wires need to have diodes put in as well. pick up all the door pin wires individually and diode isolate them so they cant backfeed into one another AND also a diode on each OEM door pin wire to diode block the BCM signal back to the door pin switch, with the trigger wire to the alarm "between" the the door pin and diode.

Would anybody happen to have a diagram of the way this should be done. I can relate to what you guys are saying a little better if I'm looking at a schematic. I understand the concept though. Thanks in advance. Boy you guys are really helpful on this forum. I have to make it a point to stop by a lot more frequently then I have in the past.

On some cars yes, but i don't believe this is needed on a Camry. The door signal won't backfeed from the BCM like an old Mustang will. 4 diodes should do it....

About the diodes: https://www.the12volt.com/diodes/diodes.asp Look at that page, about halfway down on the left. The diagram shows a two-door car, but you could simply add two more diodes to the setup, and connect them to your rear door wires. By the way, where was your install done? In Massachusetts by chance? That combination of products sounds like something some of my co-workers (from our other location) have used. Regardless, whoever installed it should fix this issue under warranty at no cost to you. It's also an issue I'd never thought of before. If I get the occasion to install this setup again, I'll check the car's domelight to see if it comes on at shutdown. Most alarm/start combination units are smart enough to ignore the door trigger at startup and shutdown, but since the PRO9233 isn't generally expected to be installed along with a remote starter, they didn't include that feature.
