-----Question-----
My 2001 Chevy Blazer's Alarm keeps going off for not apparent reason. 5 times in the past 24 hrs.
Not well like by my neighbors at 3 a.m.
What needs to be done to correct the problem? It's not windy.
Thanks, Bob

Please tell me what you are experiencing.
I need to determine whether it's a factory alarm
issue or, if it's an aftermarket system you are
dealing with.
Many veriables on this vehicle &
I Require a bit more imput please.
Is it: Headlights flashing, car horn honking
and a worded SECURITY" light in the dash flashing?
Or,
is it: flashing parking lights,
an LED in the dash area, and a siren
going off?
Let me know more on this to better
advise you on a course of action
to take, to help you to fix this
situation you're in quickly.

AnswerFCTRY ALRM DISARM lt.green is a |-|
negative triggered wire in the purple plug at
BCM (body control module.) Locate the wire,
splice into it and ground to the chassis
if you want to terminate this part of the security
system. Short of that, you would need to take it
to GM to have them diagose and reset it.
The BCM is located to the right of the accelerator pedal below the radio.
The plugs on the BCM face towards the drivers side.
If the Passlock II system is also keeping the truck
from starting, then here's what's happening:
The 10 minute time frame is the indicator that points
to a passlock problem. 10 minutes is the magic number
that says the passlock has been put into long tamper mode,
the vehicle thinks someone is trying to start the car with
the incorrect key.
If there is no aftermarket remote start in the vehicle,
then I would suggest taking it to the dealership for repair.
If there is an aftermarket remote start, then whatever method
that was used to bypass the passlock is malfunctioning.
Now don't confuse this. The reaction you are having IS
due to the GM PASSLOCK II system being breached & activated
or, it is malfunctioning. In either case, this is
what (in this car) is troubling you. The trouble
though is that the local mechanic at
the gas station can't help here.
Sorry, but the passlock is GM's way
of getting you coming and going.
There is no outside method other then circumventing
it momentarilly to allow remote start, which won't
fix your troubles.
Nope, this is a GM issue and has to be corrected there,
or an outside shop will charge you bukoo bucks
to replace the whole VATS. (VERY PRICEY $$$$!)
Sorry wish I could be more help, but if it's
intermittent now, then it needs they're technician,
they're factory computer diagnostics to fix it.
There will be a fee involved to reset it, but much less
then replacing the entire VATS-Passlock system.
If you do find another fix, let us all know.
This is NOT uncommon. It is GM's way of keeping
it all inhouse, security wise.
Let us know what you find out.
