2007 Toyota 4Runner, Compustar CS7502AS, Alarm Only

[Moved from this thread: https://www.the12volt.com/installbay/forum_posts.asp?tid=143135] As it is, opening any door does not trigger the alarm. Only the hood switch and impact sensor will trigger the alarm. The remote sets the alarm on or off though and only locks/unlocks the driver's door.

your starter wire could be used as a starter disable wire also not just for remote start but for security also,.. if someone tries to start the car without disarming the viper system the viper system will disable the starter wire, i would wire that up . your viper unit should have a starter input and starter output

Hi, thank you for replying. I don't have remote start enabled nor do I have a viper unit. I hope someone can help me with the remaining issues. My car is simi-apart since Feb 5th and these remaining issues are frustrating. I would be so grateful to finally put my car back together. That might not be possible yet because there might be a short somewhere that might be affecting the alarm module.

I haven't installed a Compustar CS7502AS, but I've installed thousands of alarms since the mid 80s. Here are my thoughts on your install. Your doors will not trigger the alarm if you do not have the alarm set for negative door trigger and if the alarm is not connected to the correct wire in the vehicle. The wire in your Toyota will show continuity to ground when a door is open and positive voltage when the doors are closed. 3 chirps when you arm the alarm sounds like an open door warning. If you are getting this with all doors closed and the alarm's door trigger wire connected, you're probably connected to the wrong wire in the vehicle. Try disconnecting the door trigger wire and arm again to see if you only get one chirp. If the alarm senses an open door, it may not lock the doors during arm.~wirewise~ Verify all wiring with your meter before making any connections!

Thanks so much for your post. I will check the wires again. I didn't think of removing the door trigger wire to see how many chips on arm. I was late returning to this thread because I just had a parotidectomy so i'm taking it easy. I think I can get back to working on my car tomorrow. Thanks again. edit - i'm not ready yet. I want to conclude this thread bur I just had my stitches removed and i'm not ready to get into solving this problem just yet. Another couple days I think I will be strong enough to resume.

Hello! I'm back. I removed the door trigger wire from the purple/yellow wire and it does indeed only chirp once to arm and twice for disarm.I wonder why that wire isnt working. I suppose it needs the dome light wire or is that a less desirable trigger? There isnt a problem with lockimg the doors, just unlocking the passenger doors

Hello, the purple/yellow wire does not seem to be the correct wire for door trigger as there is no voltage there and when connected there are 3 chirps on arm. I don't know where to go from here other than the dome light which I don't know where that wire's location is. Only the driver's door locks and unlocks. The passenger doors only lock. The alarm does arm with locking the door, but only the shock sensor and hood pin sets the alarm off.

New info: I reattached the purple/yellow wire as i saw 12v with door open 0v closed. I found out the siren chirps once to arm and twice to disarm only when any door is open. With the door closed, it goes back to 3 chirps arm. Also, closing the door triggers the alarm instantly, if it's armed while the door is open.

Look for a white wire behind the driver's kick panel that shows ground only when the door is open. Alternatively you could try connecting that purple/yellow wire to the alarm's positive door trigger input instead of the negative door trigger input, if it works as you described.~wirewise~ Verify all wiring with your meter before making any connections!

There's a positive door trigger? would I need to move that jumper back to the positive position? It seems like this is all backwards yet the door locks work correctly for the driver's door.
