Problems w/Remote Starter Automate AM1, 2007 GMC Duramax

I will try to make the short.  2007 GMC duramax loaded.  Has factory remote start.  Got the add on alarm.  They used the Automate, AM1.  My first problems were:

Arm:  Chirp..chirp,chirp   Hold remote start.  Alarm starts chirping and then the truck would start and alarm would go off.

Disarm:  Two chirps (no problems)

Took back to dealer.

New problem

Arm: Chirp   (great !)  remote start truck.  Alarm goes off.  Or the truck does not start at all. 

Disarm:  4 chirps

Arm:  One chirp (great!)

Start:  Truck starts and Alarm goes off.

The dealer installer told me that the alarm was getting a double pulse from the passenger door locks to lock and that was the problem.  I have seen the door lock do a little bump up and down when you hit the lock button. 

What does anyone think?

What you need to do is look at the LED and it will basically tell you why your alarm is going off.  its in your owners manual.  Arm the vehicle and remote start.  After you turn off the alarm you can check the LED and see how many flashes it gives you.  Post the number of flashes and it will pin point what the cause is.

good advice the owners manual is there for a reason; to give you information on your system, it amazing what can be found in there if it is read!

I have read the owners manuel.  The problem is that it is pointing to the doors.  I have checked them several times and have found no problem.   It is pointing to a trip even though it hasn't happened.  The truck is just sitting and tripping.  If I bring it back to the shop, I am going to have them remove it.  I have a feeling this thing is junk. 

Swerks, how much do you get for a tractor alarm in AB?

how bout this.....if you remote start does your dome light inside turn on???? If it does then their is your problem.  The alarm may be getting triggered by that.

I have heard this also.  I asked the last tech about it and he said that it is OK.  I do not know what the program code is to check that it is turned off for a light delay.  When they changed my module, the problem changed to this.  I am not sure that the programing is all that correct. 

Another on said that the door lock on the drivers side does a little bouncing step that will upset it.  I see mine doing this. If  anyone has run into this, I would like to know.

well, since this has the factory remote start option, i will go under the assumptin that it is a new style silverado not a "classic" (since they didnt offer factory start till new style)when you hit lock on the factory remote the dome light pulses, thereby triggering the alarm door tripper indicator, have the installer hook the door trigger to all the individual door triggers inside each door at the door lock control module, the dr frt door is grey/blk at the driver door mod, the pass is either tan/white or blk/white at passenger door mod, if its a crew the l.r. door is blue/black and the p.r. is GREEN/ blk at the bcm pink plug, he needs to diode isolate them , if hes installing automate he should have access to directechs and thats specifically what their sheet recommends for door triggers, he probably( as most of us has) tried to cheat and just tagged a domelight wire( quick check if you turn off domelight feature on dash does problem go away)

Thanks Jim,

Yes, new style.  Glad to know that these guys have probably not run into this yet with this truck.  No I haven't tried to turn off the dome dimmer option .  .  I will try that.   Also, since they changed the module, when I arm before I hit start, I have been getting the regular "one chirp", when I hit the start, the alarm seems to give me the 4 to 5 chirps while the truck starts and then the alarm goes off.  This is the scenereo when the truck has sat in the drive overnight.  It is very intermittent. 

I have been into electronics for 20 years.   So I have general knowledge of the subgect.  I understand diodes.  The door diodes are used for what?    One of the forums was talking about using a relay on dome lights for "bleed through" voltage.  I have run into bleed voltage going into electronic relays (thyristors) instead of hard contact relays before.  They build up a voltage over time and then discharge unexpectedly.  I have to isolate them with hard relays.  Get back to you on the overhead light.

Thanks

the diodes are to isolate the 4 independant triggers as the alarm has one door trigger input that you will be connecting to 4 seperate feeds, so the relays are to keep them from being tied together which the factory has a reason to seperate them we as installers need to keep them seperate so as not to cause a prob.
the reason i suspect this is now the prob is automates will give warn away chirps before fully triggering when you open the door, and when you hit lock on the factory remote it will pulse the domelight therefore triggering automate if its hooked to the domelight instead of independant triggers
good luck
