Disconnecting the battery has nothing to do with it. Its totally a separate
system on that model. That may be the case on newer vehicles that utilize a
different type of theft deterrent system. On the Camaro, the system does not
"reset" especially after a battery disconnect.
I never got why people refuse to pay for diagnostics. There is no
ploy to lure you into the dealership to steal all your money. I know $90.00
is a lot of money and in my opinion that it is excessive. The dealership
technicians don't get to set the labor rate, that is set by the suits up
front. And don't think for a minute that we get paid even 1/4 of that $90.00
an hour. The reason why the dealer wants you to bring the car is to check it
out is because it could be any 1 of several faulty components. You can't
expect them to guess and tell you whats wrong over the phone to have you
replace the wrong part? That would be like asking a doctor to diagnose
cancer over the phone without running tests. Why is it unreasonable to pay
for auto diagnostics? I can list the different components for you to change
one by one and you can spend well over $1000.00 until you get the light to
go out, or you could bring it to me, let me test a few components and tell
you exactly which one needs to be repaired or repaired for a lot less. At
worst, if you didn't want to spend the money on the repair after I present
you with an estimate, you will have paid $90.00 and know what exactly is
wrong with your car and maybe you can tackle the repair yourself. Its just
not that easy to diagnose things over the phone or newsgroups.
I can tell you one very common fault that happens a lot on VATS systems.
There are 2 wires that lead up the steering column from under the dashboard
that go to the ignition cylinder. Those wires help the theft module "read"
the chip on the key. From the ign cylinder turning all the time those little
wires tend to break a lot making a ignition cylinder replacement necessary.
That harness is part of the ign cylinder. That is just one of several things
that could be wrong, its just the most frequent one I've seen. The chip in
the key could also be worn. Both of those issues will also keep the vehicle
from starting with the security light on. Again, without looking at your
vehicle and diagnosing it by running tests, those are my best guesses. Good
