SmokesGTP Posted February 19, 2003 Report Share Posted February 19, 2003 I just got a SES light on my way home and I followed the instructions on shawns site but their appears to be a plastic blocker on the "A" port of the connector. Being a 94' its still a OBD1 right? If anyone could help me out and tell me where to put the clip so I can pull the codes it would be very helpful.

brian89gp Posted February 19, 2003 Report Share Posted February 19, 2003 The 94 is some half assed hybrid. Not OBD2 yet but not OBD1 either. The only way I know of pulling the code is with a GM scanner. Quote Link to comment Share on other sites More sharing options...

Redfox340 Posted February 19, 2003 Report Share Posted February 19, 2003 Autozone... if there's no way you can pull them... they can. Is it drivable? - RedFox340 Quote Link to comment Share on other sites More sharing options...
toastemcutlass Posted February 19, 2003 Report Share Posted February 19, 2003 so do we 94 owners have what they call the obd 1.5, yes they exist just not sure what year. the other thing is it would explain why I couldn't get the code off mine along time ago, I had a block in the plug hole too and was confused.

GnatGoSplat Posted February 19, 2003 Report Share Posted February 19, 2003 so do we 94 owners have what they call the obd 1.5, yes they exist just not sure what year. the other thing is it would explain why I couldn't get the code off mine along time ago, I had a block in the plug hole too and was confused. Sort of, but not really. The 3100's in '94-95 had an OBD2 compliant PCM, but wasn't fully OBD2... they had the flash ROM, faster CPU, and more RAM like an OBD2 PCM, but was made before OBD2 was standardized. Those would probably be considered more like OBD1.5. The 94-95 3.4 DOHC PCM has the same casing, connector, CPU, etc. as OBD1. Only thing is they added SFI, MAF code, and removed the diagnostic connector. For all essential purposes, it's OBD1. Just missing the diagnostic connector (thanks, GM).

cutlassdude96 Posted February 19, 2003 Report Share Posted February 19, 2003 if you have the 16 pin OBD2 conector in a 94-95 car, ground ports 5 & 6. Quote Link to comment Share on other sites More sharing options...
SmokesGTP Posted February 20, 2003 Author Report Share Posted February 20, 2003 I thought the ports were letters? and there is only 12 pins from what I can see? Quote Link to comment Share on other sites More sharing options...
toastemcutlass Posted February 20, 2003 Report Share Posted February 20, 2003 the connector is there and when I went to the trans shop a year ago he read the speed of the car, temp and other things but the normal pins you connect to get the readings are different or atleast one is blocked off.

GnatGoSplat Posted February 20, 2003 Report Share Posted February 20, 2003 Oops, yeah, I mis-stated. The connector is there, but the diagnostic PIN is missing. The slot where it's supposed to be is just completely empty, although the ALDL, Ground, and other pins are still there. This only applies to all 94-95 3.4 DOHC.
