Do codes get stored in an OBD I computer or does the SES light have to be lit for a code to show up? Sometimes the SES light comes on in my '95 Z after driving about 1/2 hr but usually goes off after a few minutes. It is never on when I start the car or when I'm actually planning on getting the car scanned.

The codes are stored till they are cleared by a scan tool.

Take the car to Advance Auto, they can scan it for free!

Didn't think advance/auto zone can read codes on a '95 - they're OBDI with an OBDII DLC port?

How do you read the codes on an OBD1 comp?

Yeah, pretty much any free auto parts scan place will not be able to read the 95 because of the newer port/older computer oddity.

To read it you just need a cable (akmcables.com, moates.net, etc) and some free software.

Do you know if any of the free software works on a Mac laptop?

if they have a GOOD scanner they can...My actron scanner will read OBDI and OBDII and came with cables for GM, Ford, Chrysler and even a few forein cars (those cables are still in the wrappers!). It came with an OBDI cable and OBDII cable for GM - it will read ANYHING as far as I can tell. It certainly reads my '95 with OBDI computer and OBDII connector.

Not natively, but you can use parrellels/boot camp or virtual pc for pre-intel ones. I've used it with virtual pc on a powerbook g4 and never had a problem.
