the old vats agian
I know I have seen this on here before when I was trying to get my vette running but looked back about 30 pages and no luck so I will just ask
my vats has been messing up wait a bit and start it
but its got to the point it takes days to start
now it is out key ohms at 23.2 which is too high from what i can tell
how can I bypass this all the way
something about a green and purple wire to ground?
dont want to mess with the ressistor just want it gone all the way
get sick of towing the car home

I don't have vats anymore-but jfb is the man to answer your question.
I thought the value was between 1-15? anyway, if you can't find it in search, find jfb and I think he may have it posted on his site, or go to the tech site and just page him, he's a nice guy.
just from memory, I thought you had to find the key value, get a resistor of the same value and connect it between the two vats wires, BUT don't go off my memory-it's kinda shot.

as far as I can tell the 1 thru 15 breaks down to this
but I am wanting to do away with this too
If you have a digital volt meter, set it on ohms mode and measure the resistance of the pellet on your key. The BCM is programmed for a specific resistance value. The BCM measures the voltage drop across the key pellet. If it is within +/-10%, then the car will start.
The 15 resistor codes are:
Key# Value (Ohms)
1 392
2 523
3 681
4 887
5 1130
6 1470
7 1870
8 2370
9 3010
10 3740
11 4750
12 6040
13 7500
14 9530
15 11800
If you're getting 146, you probably have a VATS code 6. You can set where the decimal point goes, but the point is the number is within +/- 10% of the value for #6.
