QuestionQUESTION: All key related functions are dead. Take the white (out) socket out of the ignition switch, and power restores to the switch. Remote lock does not work bur the rest do. There is no alarm light lit on the dash. Windows, code sender and half the fuses in the interior fuse block are dead including the one to the Ignition module. I feel the factory alarm has gone nuts and shut everything down. I've left the key switch on and other resets and nothing works. I can't find a valet. How can I disarm this thing for good?
ANSWER: This vehicle has the GM Passlock II immobilzer
anti-theft system. A bypass is required to circumvent.
or, it will (as it has here!) lock down the fuel injector
rail, and you will need to tow it in to GM for
evaluation, and resetting.
I suggest the PLJX bypass kit to get around
this issue.
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.
Hopefully, 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.
