Questionmy 03 impala's security light comes on and the car won't start from time to time, i have been looking online about this passlock system i have one mechanic saying its the starter, and the other saying the passlock, i am confused and feel as if I'm not trying to spend an arm and leg getting fixed. what can i do??
AnswerOk, :>( Bad news I am afraid.
Somewhere along the way, the passlock system
was reset. This is the problem, and the guy who
figured that out is the one you want to talk to.
This vehicle has a the PASSLOCK II key
based engine disabling system.
Your's is on the verge of malfunctioning.
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 though, 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.
The catch here is that the car engine
MUST start to program this module or it
won't work.
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.
The fair rate being around 50. to 75.
for labor.
