Car Alarms: alarm chevy truck 2007, buick rendevous, cadilac escalade

Question
How do I tell if my truck has a factory alarm on it that has been disabled? 2007 Chevy 2500HD Silverado

Answer
It has 2 definately. 1st is the horn honking headlight flashing
part of the security. The second is the PASSLOCK 2 fuel rail
inhibitor circuit system in MOST ALL trucks of that year from GM.
(some exceptions would include the Cadilac Escalade, the Buick
Rendevous. These are passkey 3).

Add in the prospect of someone adding an after market
system to the mix and you have allot going on in there.

And it's unlikely unless you did some surgery under the dash,
that's it is disabled.

I hope this helped.
