Code definitions

[JEFNLSA]

SES light on...

Going to have Autozone do a "free" code scan after work and I'd like to know if there is a list of the code definitions available for my LT4 here on the CAC?I'm taking it in for an oil change this weekend and I'd like to be ahead of the game by having the replacement part in hand so when I go for the oil change they can also replace the part/s (02 sensor etc...) at the same time. I'm trying to avoid a scan fee as well as paying "their price" for the part.

Is it that simple...run a scan, pull up a code, define it, buy part/s and (yeah I know :L ) have "them" installed?
Thx guys,
Jeff

BTW...Figured out the intermittent SYS is "new stereo install" related thanks to the :BOW so I bought the resistors as stated and have an appt for the fix. Wish I'd known about that sooner.

Between the SYS and the SES, it's like Chinese Water Torture in my car....AAAHHHHH....I'm goin' "blinkin" crazy!!!!

The best thing you can have in the toolbox is a GM Service Manual. Go to www.helminc.com and order one for your car. They are the same manuals that the techs refer to and provide comprehensive information on diagnosis and repair. You can also find them on eBay.

The C4 books are a two-manual set with one being general repair and the other is driveability and electrical diagnosis. Between the sections, every ECM and CCM code value is described along with trouble-shooting procedures for the codes.

AutoZone may tell you what the code means and of course they will sell you a part that relates to the code. But simply replacing the part does not necessairly mean that the code will go away. A code can be set when any component within a system fails. For example, within a individual system, there are relays associated with components. The relay can be bad resulting in a code but the part that the relay controls can be bad which may also set a code. That's why a diagnostic procedure and the trouble-shooting chart is shown in service manuals.

Yeah...my Chiltons is weak (to say the least).

There was a thread where they had all the codes listed for a 1997 and someone said that you could find the code definitions for other year Vettes here as well but I sure can't find them.

Any ideas?
