Pulling Codes from a 96
How do you go about pulling codes from a 96? I checked http://www.c4vettes.com/ecm.htm but they only list through 93 and say I need a special tool or the service manual for a 96. I hope theres a way without the tool because I dont have it. Any help is appreciated. car only has 41,000 on the clock and im really upset its throwing codes.

Take it to AutoZone and they'll pull the code(s) for free.
On our '96s, you need either a scan tool or diagnostic software & a laptop to pull PCM codes.

Just make a jumper wire and connect pins 4 and 12 on the diagnostic port below driver's footwell. Then turn ignition to ON, do not start car!
It will start blinking codes at you.

Well, I'm kind of curious now as to what others say. My car is a 96 but has a 95 PCM so maybe the procedure I mentioned does not work on a 96??????

This will NOT work on a '96 with OBD II. You can pull CCM codes this way, but not powertrain codes from the powertrain control module (PCM).
Are you saying that this procedure is for pre-OBDII? Or that it is entirely bogus?

Re: Pulling Codes from a 96 (VetteLT4)
ok so before i bite the bullet and take it in, its certain i cant pull SES codes on my own without a special tool?
Correct - you need to have a scan tool of some sort.
Most auto parts stores are now selling relatively (~$100) tools that will read and reset OBDII codes. It's a decent tool for the tool box if you expect to do any of your own work on a 96 or up vehicle. The good thing is that it's standard so this will work on pretty much any 96 and up vehicle.
They way I see it, it's not really different from any other tool you buy. A little more expensive maybe, but it's still not a wasted expense. Figure that a trip to the dealer to read/reset a code might cost you $40 or more (and time!) and it'll quickly pay for itself. At least that's how I see it...
It's really nice for when you do some work under the hood and either forget to reconnect something, or otherwise cause a code with no real failure. Sucks having to go to someone else and pay them to fix your "oops" :D

Will it work on OBD I? I ask because I have seen some procedures for getting all codes from ALL modules (e.g. PCM, rtd, ccm,etc).
