I am currently working on a '94 Corvette. Not sure what model, but i
have been trying to do the diagnostic's on it and my MT2500 scanner is
telling me that it cant communicate with the computer. I have been
told that none of the ealershiops have the paper copies anymore of the
wiring. Its all on computer now and they wont take the effort to look
it up for me. I have been told that the fuses and possibly the fusable
link off of the starter maybe the reason. Does anyone have the service
manuals for this car that shows the wiring breakdown for the main
computer so that i can check for power on the appropriate wires? Any
assistance would be greatly appreciated.
What you need is the Helms manual and sadly it's currently out of stock:
Join the Corvette Forum and ask over there.
Someone will have it and either let you borrow or buy it.
There's no reason that the local stealership won't have shop manuals for
your car. They just don't want you using theirs.
The reason your scanner won't work is because you're 'Vette was made in
between the transition between an ODBI car and an ODBII. You'll need an
OBDI scanner with an OBDII ALDL connection.
What is wrong with the car?
No start. Has spark. No fuel pressure. It has been sitting under a
cover for the last 11 months. I have a MT2500 Scanner w/OBDII
connection. I have the other 2 connections for OBDI and previous. The
OBDII connection is the only connection that i can find. When i put in
the VIN # the scanner tells me to use the K9 (personality key) and the
OBDII connection. After I do all of this input and go to connect it
tells me that the scanner cant communicate with the computer. IT did
mention something about the ALDL connection. But Im not familiar with
that connection type. I have to get with the owner of this car and see
if i can get it moved away from the wall it sits near. I cant see the
fuse box on the right side of the dashboard. This car needs alot of
TLC in order to make it worth more than slavage value as it sits right
