QuestionQUESTION: i have a 99 Cadillac catera and the alarm just recently started screwing up. when i unlock the car and open the door the alarm goes off, when i put the key in the ignition and turn the key the alarm goes off , if the car is unlocked and i open the door the alarm goes off,the car still runs perfect while the alarm is on. the alarm will not turn off until the 5 minutes or so its on for. any help would be greatly appreciated
ANSWER: "GOING OFF?"
I need to determine whether it's a factory alarm
issue or, if it's an aftermarket system you are
dealing with.
Is it: Headlights flashing, car horn honking
and a worded SECURITY" light in the dash flashing?
(doubtfull since none of the notes show this
car as having a factory alarm system)=FACTORY
Or,
is it: flashing parking lights,
an LED in the dash area, and a siren
going off?= AFTER MARKET
Let me know more on this to better
advise you on a course of action
to take.

QUESTION: oh sorry forgot to say its the stock factory alarm."Is it: Headlights flashing, car horn honking
and a worded SECURITY" light in the dash flashing?

ah what i meant by goin off is that the alarm sounds, if thats a better way to put it, im not good with words. the alarm turns on even when i dont have the doors locked, flashing lights+honking horn and security light on dash
Answer:>( Bad news I am afraid.
Somewhere along the way, the passlock system
was reset. Possibly when or, if the battery
was removed. This is a problem.
This vehicle has a the PASSLOCK II key
based engine disabling system.
You can attempt to put the key in the ignition,
turn it on to just before cranking and then leaving
it that way for 10 mins. After that,
some PASSLOCK systems will re learn the code
and allow for starting. But if not, the system
will either need to be seen by GM or, a bypass module
is required to circumvent.
If left unchecked, it will continue to lock down
the fuel injector rail, and you will need to tow
it in to GM for evaluation, and resetting anyway.
Bothersome, but can be fixed.
I suggest the PLJX bypass kit to get around
this issue. www.PASSLOCK2.com
This Passlock Bypass Module is designed to momentarilly
allow the engine to remote start by sending a proper
coded pulse to open the fuel rail passlock injector
cut off circuit.
The output from an alarm/remote starter
would then shut down the pulse, once it has detected
the engine has engaged, and preserve the integrity
of the passlock system.
That is it's designed purpose.
However, in your case, this input wire on the PLJX module,
instead of going to a momentary ground pulse from
an alarm/remote starter,
would go to a constant chassis ground, through
the bypass module, grounding out the PASSLOCK.
The PASSLOCK would then always be bypassed as long
as that wire is chassis grounded.
I can not speak about a damaged passlock system,
like if a thief has destroyed it, because I do not
get into this part of GM'S security application.
But as a happy coincidence to installing
after market remote starters, this does work on bypassing
passlock in most all GM vehicles we've run into,
including your year GM vehicle as well.
Also, this is a self learning, resistor sensing
and adjusting module. Once the VATS wires have been tapped,
you would press the program button to learn,
and it does. The car should then allow start
with any hardware store key.
It will on yours as well.
You might want a car alarm installer to do this
for you, the fair rate being around 50. to 75.
for labor.
