TylerW Posted May 21, 2006 Author Report Share Posted May 21, 2006 ok..well I don't understand why they decided to make it so difficult for us home mechanics to simply access the trouble codes Thanks Quote Link to comment Share on other sites More sharing options...
DiscoStudd Posted May 21, 2006 Report Share Posted May 21, 2006 As soon as GM switched the PCM's to flash memory, the days of pulling your own codes were over. All GM's 96 to present (which are OBD-II) will need a scan tool to pull codes. The 3100-equipped vehicles began using flash-style PCM's in 1994 (the 94 and 95's were still OBD-I, but since they used a flash PCM, most people refer to them as OBD 1.5) ...

GnatGoSplat Posted May 22, 2006 Report Share Posted May 22, 2006 If you have the 94-95 3.4 DOHC, it's still a regular old OBD1 PCM, just missing the diagnostic wire. I don't know why, maybe they needed all the pins when they switched to SFI. Anyway, you can use an ALDL serial interface (usually $40 on eBay) and using a program like EFILive or CarBytes you can get the codes. I have a definition file for EFILive you're welcome to have a copy of, not sure how complete it is though. I had to write it myself because I couldn't find one out there. You're able to check for engine and also ABS codes with my def file though. Quote Link to comment Share on other sites More sharing options...
