Be aware. A damaged Passlock s system may not allow bypassing it because bypass procedures are based on a working system before bypassing it. You'll find many guidelines here and vroom YouTube about cutting the white wire of the three wire Passlock harness connected to the ignition lock assembly. When you find procedures, you can try it but expect failure while hoping to bypass Passlock.

Default SOLVED !! Re: bypass passlock procedure specifically for 2002 SC1 SOHC

Default Re: 2002 Saturn SC1 coupe has security issue
Finding out the correct wires was not very easy
I researched Saturnfans, Youtube and posted questions on Bing

I found many different answers concerning passlock bypess
But for my particular year, make and model, nothing exactly came up.

Different colored wires and different locations and different year makes and models so I just tried to look for some kind of common denominator.

I did find one site ....

triplew.hiluxmotors.com/how-to-permanently-disable-gm-passlock-system/

.... that had a good explanation of procedure but again, not specific to my situation

That is where you came in.
You knew exactly my year make and model and my situation and you pointed to the 3 wires coming from the ignition specifically.
You explained very clearly the different stages of security light and what was normal and abnormal
You also explained the door chime with no key in the ignition which told me that it really did not have anything to do with the lockout.
You also encouraged me to go through the process of elimination to exclude any other source of spark or fuel problems.

We both agreed I had really nothing to lose if I started cutting wires but cautioned me that it may not be the solution.

After researching for a week I was finally bold enough to cut wires
My colors were solid Yellow, White and Black

I did cut the white but nothing changed.
Spliced them back together and capped them
The website noted above said nothing of a white wire to help anyway.

It did give me a range in resistance but not specific.

I tested the OHMS in the wires as instructed
(cut yellow wire in half making sure both ends could be worked with stripping some insulation from both ends
Then strip NOT CUT some insulation from the black wire)

With a multimeter, I measured the half of the yellow going to the ignition and the black for OHMS)
I could not get a definitive number as it kept bouncing around but the most common range was around 5000

I bought a cheap pack of resistors from Canadian Tire ($14.00) and chose a few different ones to try.
Resister wire goes from the other half of the yellow that goes to the BCM
And to the black
Top half of yellow used to measure resistance is now useless to me and was simply capped off

First I tried a 9100 and all of a sudden the security light started flashing quickly.
Didn't start so i thought maybe I had to do the relearn process. (OFF to RUN with 10 minute intervals 3x)

Nope

So I went to the lowest resister I chose 4700 and security went out and my poor old Saturn fired right up.

That's my story and I hope it helps many others
