I'm trying to fix my factory alarm. The problem is that it blinks only and doesn't go in armed mode.
I fiured out that there is something wrong with it's sensors.
I tested all the wires in the harness coming to the module, and found at least one suspicious wire. This is the yellow one - #6 (or 3) in the "top" row. (I mean the row which is closer to the connector's "key").

Any idea what this wire suppose to indicate?

Thanks in advance.

 

Anybody? Craig?
I know some of you have FSM!

Come on guys! Help me. What is the yellow wire?

 

that goes to the drivers side and passenger side (it splits later) door locks and should have ground signal when the key cylinder switch is "tampered" with
it looks like that just means if the key cylinder is removed though and I doubt that's the case for your car

 

It is exactly what I expected, and it is my problem. I have there constant -12V. Looks like there is a problem in one of the door locks.

Thanks Craig. You are very useful

 

Hmm, maybe you could try removing that wire from the harness going into the alarm. Usually there is just a small plastic clip or something holding it in place and then you can pull it out. You could try that to be sure that's the problem. You should be able to slide the wire right back in if it's not the problem.

Glad I could be useful

 

I tried for 15 minutes yesterday - no luck. Don't want to cut the wire. Anyway I'm going to take care of my doors soon - to grease window guides, to clean keyless entry keypads etc. So I'll take care of the lock tamper contact as well.

Anyway thanks for the advice.
