First Alarm, 97 Honda Civic

Faulty unit?

I have not a clue lol. Everything seems to work just right except for that one issue. Well I'm glad we narrowed it down to that being the only problem. I guess waiting for the dome light to switch off is not going to be so bad. It's not like I plan to use the remote start all of the time I want to drive the car. I doubt that I can get my hands on another brain unit being that they are so expensive.

Is this a 2 door or 4 door? You should be able to isolate the door pins with diodes and wire the dome light relay after the diodes. Wouldn't be too bad if it is only a 2 door, would be more cumbersome on a sedan. Does the dome light output have any secondary uses? There may be different modes in the programming to get it to act differently. I would doubt it would be a faulty unit - faulty programming maybe!Kevin Pierson

It's a 3 door hatchback. The main lead to the dome light is triggered by the passenger door. The driver door just taps into it but it completes the same circuit as the passenger. I don't think the actual light is the issue at this point. It's the alarm triggering the domelight output upon completing the MTS mode. I'm not sure what programing there is to complete for this output, i didn't see it on the menu.

If you cut both door pin wires, and install diodes (bands facing towards door pins) and then run wires from each door pin to the alarm door pin input you can then hook the dome light output to the dome light side of the diodes and therefore your dome light output can come on (whether it is right or wrong that is a different question) and it won't trigger the door pin.Kevin Pierson

The diagram below illustrates what I'm understanding from you. The brown dotted line from the relay to the passenger side before the diode is your suggested line. Yes, I have my trunk trigger tied in with instant trigger. While testing, I also removed the trunk trigger and left it connected, it didnt make a difference.

No, the dome output should go to the door switch side. Look at this:- 3FF_dome.bmp

Howie, that is close, but not quite. You need to reverse the "to alarm" connection and the "30" connection. The alarm needs to trigger directly off the door pins and the dome light activation needs to be isolated from those points by the diodes.Kevin Pierson

So is my diagram correct? 2 diodes and relocate the wire coming from 30 off of the relay is what I'm understanding.

Sorry Kevin, can't seem to get my head around, Happy Birthday by the way.
