Default Passlock 2 code values

Does anyone have a list of the values assigned to passlock 2?
ie code 10,9 8 etc.

those look like PassKey values not PassLock 2(II)
Ive been experimenting with bench test so I can bypass the VATS
without reprogramming
code 10 is working with a 15K resistor altho its within the voltage threshold
its not exactly dead on (4.27v in vehicle vs 4.31 with fixed resistor)
what is important is the BCM is unlocked and showing code 10 as being valid.
so it should give a green light to PCM for fuel enable.
I would like to get a little close to correct value(if I knew it) just incase of quirks that sometimes
happen with VATS.

To start with your mixing terms.

Vats is NOT passkey, passlock or anything else... Vats is a type of system used in the late 80's and into the real early 90's.So using the word vats and passkey together is a contradicting statement of system types. Using the term Vats as slang works in most cases to get the point across but for what it sounds like your wanting to do you should avoid mixing terms and stick to the name of the specific system your wanting to work with.

Your next issue will be that if your wanting to have multiple values your going to have to relearn the system every time you change the value. Pick a value and live with it, your going to have to relearn the PCM or the Key code every time you change things around so why not make this simple and just find a value that works and leave it alone?

Very familiar with the terms Passkey passlock Vats etc perhaps anti theft system is generic enough
title of topic should say enough.
Not all systems use the same values,hence again the topic.
why not get close enough to the OEM value that the BCM has already been programmed with.
one less thing to redo...have had some that refuse to relearn.
wanting multiple values for multiple applications,not that hard to list and use.
I would share them If I knew.
I'm guessing you don't know the values of PassLock 2 also?

It's hard to put a resistor value on that system since it's voltage based rather then Resistance based. Yes technically they are both converted to voltage readings but the system your working on was a lot easier to fool. I've disabled a number of them by splicing 2 of the wires together, I've also used a couple of different remote start bypass modules to do this with. If your unable to come up with resistor values to wire in directly maybe you could extract equivalent values from a bypass module? All the newer ones just clone the key but if you look at some of the older stuff.....like 15-20 year old stuff they used dip switches to assign a key value.

you might have missed it but look again at the scanner and it says valid code 10.
You can use a pot to tune in and will notice as the value changes the code number changes also.
agree that its voltage based that's why I posted the voltage readings BUT resistance value is what determines the voltage. its 5v in and "X" v out. Just trying to get as close as I can.
Surely theres a table of values somewhere....

bringing this back from the dead to see if anyone has these values for Passlock II
