Re: SES

I too was under the impression that GM after 95 was OBDII and prior to 95 was OBDI. Is this wrong?

and also the understanding of both Chilton and Haynes :-)

Warren, you have OBDI if your SC is '93. Yes, you can buy a code reader from your local WallyMart for under $30. I dont know how much they are in the auto store.

On OBDI if you are handy and thrifty, you can use a paperclip to span the connectors also, but I prefer the inexpensive, never fail reader. Perhaps the one you looked at had an LCD, those are more expensive. The cheap one or the paperclip will flach your SES and Temp lights in secuence to give you a code, all you gotta do is count'em and look in the accompanying book.

Mine is the Innova #3123, came with the reader and code book for all early GM models.

Hope that clears this up and you can find that reader. marx404

Don't know - sounds like an interesting unit. It would seem that someone would have developed a computer with adjustable parameters at a reasonable price. There sure seems to be a demand for it.

reader

You don't need a reader like that on pre-OBD II GM vehicles, just a jumper wire:

No bands in the TAAT. That stupid thing is like a Honda - non planetary. probbably the most idiotic design out there, uniqe in all of GM to Saturn. I'm guessing they did it because GM was in a 'copy the Japanese' mode when they designed the car but then, Honda automatics aren't anything to brag about either, IMHO...

Losing reverse is a common problem in these things, IIRC. You really don't want to know what the fix costs...
