remote start problem, 02 s-10

Hello everyone! I am new to this forum and I enjoy working on cars. I had a Code Alarm CA-670 installed in my 02 Chevy S-10. When I use the remote start feature, the truck will start, but then the alarm will go off and killing the start function. It doesn't do this all of the time. I have talked to the installer and was informed the all alarms with remote start have this problem, when it is cold outside. I think, I was just being brushed off. I am not afraid of the wire monster, so if it involves moving some wires around, I am all for it. Thanks, Don Z.

The system is an alarm/start combo with 2-way communication. When I bought the truck, it had a factory alarm. A bypass module was added, during the install. I think a wire has been attached to the wrong circuit. The alarm only does this when it is cold out and not all the time.

Needless to say it should NOT be doing that and all remote start al arm combos do NOT do that... Sounds like installer error to me.A DMM is a beautiful thing.

all huh? my audiovox prestige unit does. ive seen and installed tons that will.

wire nut, what code is the led flashing to tell you what set off the alarm?

I will have to look, the next time it does it, again. I didn't think to look at that. Good idea! I didn't want to have a hole drilled in the dash, so the LED was put inside the fuse box, located on the side of the dash. The factory alarm has a light in the dash that tells people that it is armed. Don Z.

O.K. here is the routine. I press the start button twice. The truck honks two times and the display, on the remote shows the truck starting. The display also shows the doors unlocked. But clearly they are not. As soon as the truck starts, the alarm goes off and the remote start is shut down. I checked the LED, on the aftermarket alarm, and it is a steady flash. No codes showing. Now, I don't know what alarm is going off, because, I had the aftermarket alarm wired into the trucks horn. There is no siren. This only happens when it is cold out, "sometimes". That is why it took me a while to respond to this thread. Don Z.

check your hoodpin if you have one. make sure it is not loose and grounding out from vibrations during start up. also try disconnecting the horn from the remote start and if it still goes off then you know it is because of a factory alarm. also check your ground on the alarm

Is it the siren from your aftermarket alarm that is going off, or the horn from your factory alarm?  I would guess from what you wrote that it is the =factory alarm that is sounding and would guess that the wire sent to disarm that is either cold soldered, or not connected.  It should be a light green wire in the purple connector at the BCM under the center of the dash.Think. It's not illegal yet.
