2007 Toyota 4Runner, Compustar CS7502AS, Alarm Only

Wasnt able to edit my last post. I tested again. When i open any door the alarm wont trigger. If i gently close any door, so the shock sensor wont trigger, the alarm is triggered.

Is your multimeter showing -11.24 volts or +11.24 volts when testing the door trigger wire in your truck? Are you using the correct door trigger input wire (connector 3: wire#3 red/white wire) from the Compustar module as shown in this image? Remember to set the door trigger input polarity in the Compustar module. Also, unplug the alarm shock sensor during testing.

I believe it's +11.xx volts and i did move the jumper over. I'm curious about the 2.2 volts when the door is closed./ I will double check the polarity in the daylight.

both of the voltage readings are positive. Does my car have a short somewhere that it's reading 2 volts instead of zero? (Perhaps why I keep seeing less than 12 volts at my battery yet it has no trouble starting - it's a larger yellow top.)

Let's try a different wire. There is a "red with yellow line" wire that also tests as a door trigger wire in your truck.    Again, use your multimeter to test the "red with yellow line" wire following the same procedure when you tested the "purple with yellow line" wire in your truck. The "red with yellow line" wire is in the middle plug of the BECU as shown below. Just make sure that the jumper, for the door trigger input, is in the "negative" position of the Compustar module before splicing.

Hello, i dont even see one volt with the door open. Open=.08. Closed=.10. The old wire still sees 12v open and 2.2v closed Will you comment on the 2.2 volts when closed. There must be something wrong which may affect what im trying to connect.

The voltage should return to zero with all doors closed. i will not be able to help you troubleshoot the 2.2volts when doors are closed. My wife has a 2005 4runner and i tested the "purple with yellow line" door trigger wire as well as the "red with yellow line" wire and both wires return to zero volt when all doors are closed. For the "red with yellow line" wire make sure you are piercing through its insulation, your multimeter should get a reading.

I imagine if it's showing any volts, the insulation was pierced. Looks like I have a faulty alarm...well maybe not. I didnt move the jumpers the first time so maybe something was damaged but then that would not explain the car's electrical 2.2v reading. edit** YES it might. The red/white wire from the alarm might be feeding the purple wire 2.2v. I don't know, just a guess..... thanks again for your time. oh yeah. what about the dome light connection? maybe that will work. Edit - something happened. I unplugged that #3 connector with the red/white and tested. Im getting 12v NEGATIVE door closed and .47v neg door open now! (on purple wire) I have to go back and make sure that purple wire plug was plugged in.

I sourced the pos 12 v from the wrong wire on the key plug. Its back to where it was before. Well, if its not going to work with door opening its ok. Most will smash a window anyway and that will set the alarm off. My next problem is programing for double pulse unlock. Either i dont understand the instructions or something is wrong. What do you or anyone else think? Another edit - im getting -0.47 across the purple wire and ground

ok, does anyone know how to hook the dome light as trigger? Also, does anyone know how to program for double-pulse door lock?
