remote start, 2001 suburban

I've seen and read the https://www.the12volt.com/installbay/forum_posts.asp~TID~50790~PN~0~TPN~4

Question, I have a Avital 4300 with a DEI 1701G installed in my 2001 Suburban. I had it done just because I don't have the time (needless to say, I should've done it myself, what a disappointment on the install job - we wont even go there).

Anyway, tonight I realized that the only door that is protected is the driver side. When I open any other door(s) including the backdoor the alarm will not activate. I have a feeling the installer used the wire for the driver side door only. Is that even possible.

How do I fix this? I want to make sure that the the alarm will "activate" any of the 4 doors or the backdoor open. This would be nice since I have the Avital set on passive door arming.

Any help would be greatly appreciated. Thank you!

The remaining doors are picked up at the ECM blue/white (NEG)-

Thanks for the reply, unfortunately I wouldn't even know where to begin to look (newbie with Chevy). Any more detailed info would be great.

Also, when you say remaining doors, will this include the back tailgate door as well? And do I connect this to the orange of the Avital 4300?

When you drop the bottom of the dash, look under the stearing column. there is your ECM. 3 plugs facing you.

Should be in the middle plug, top row of wires on the connector, second wire from the right! ( Pin B-11 )

Thanks again for the help, I found it. Now being a newbie what wire do I connect that to the Avital. Also, which one is for the back tailgate door, I noticed that wire only does the "other" 3 doors.

KarTuneMan, thanks for the help.

I got it, everything works as it should now.

I have a problem and I dont even know how to explain it. The same thing happened to my wife couple of days ago and it happened to me tonight.

We were walking out from restaurant, I started the Suburban remotely and all was good. By the time I crossed the parking lot and got to the car, I unlocked the doors with the Avital remote then seconds later the OEM alarm (car horn) went off.

Why is this happening? Is there a wire I should check that might not be installed right?

Since this happened to my wife she now carries both remotes the OEM and the Avital. The OEM is only used just in case it happens like tonight.

Hopefully this makes sense to you all.

Any thoughts or advice would be greatly appreciated.

You need to connect the factory alarm disarm wire(which is at the BCM, purple plug, pin B3, lt. green wire) to the alarms pulse before start wire to stop this from happening. I think the wire is Lt. GREEN/ balck on plug H2 on your alarm...

Mike,

Thanks for that info. I looked at the install guide then also looked at what I have and sure enough you were right about the wire colors. To top it off the installer (Audio Express) doesn't even have anything connected to where the H2 harness should be plugged in, so I can't even do it myself.

I guess they purposely did that since that is the same harness for the ch. 4 and 5, who knows?

I am on my way back there in 20 mins to have them resolve this. My only question now is should I have them connect the factory re-arm as well which is the GREEN / WHITE on the H2 harness?

Thanks again to this forum and site for the wealth of info you all have for newbies like myself.

It's done.. just went back to the place and they wired the factory dis-arm. They had to get a harness from another box since they didn't have it. Hopefully this is the last time I will be going back there for a problem with the install. I've been really patient with the guys and they have been very helpful in fixing the problem. It's just sad that I have to tell them what the fix was with this and the last problem I had. For some reason they had no clue... and that's thank to this site and you all.
