'82 Computer Codes-List
I have searched three manuals and the forum with little or no luck, not any mention of a list of codes and how to get the codes off computer. I understand it is an easy procedure, but what the heck do you do?
Thanks! terry |

Thanks!!!! :thumbs: Good link too. There seems to be so much junk and "selling of junk" on the net that it clouds good info during a search. terry |
IMO, I've found that the 82 Corvette shop manual from GM is the best. All the other manuals leave a lot out. If your manual doesn't have all the codes and diagnostic charts, you need a different manual.
If you have an old laptop computer with a serial port, conneting with Winaldt and checking what the computer thinks is really nice to have when trouble shooting the 82. http://winaldl.joby.se/ And making a cable was pretty easy, if you have even a little soldering skills. 82's don't need R3 and R4. http://winaldl.joby.se/aldlcable.htm And if you have problems this thread might help: http://www.crossfire.homeip.net/cfte...TOPIC_ID=11355 |

Plugged it in, the only thing it did was make the hood damper open and close :eek: , go figure. Im going for the PC stuff. Thanks all! tt |

I'd also recomend the Assembly Instruction Manual (AIM). It has the exploded views of assembly you won't find in any other repair manuals. |
Don't see it mentioned but here is how to retrieve the codes:
Remove the ashtray...see the multiprong plug? Two ports closest to the driverside are the ones you need. Get a stiff wire and bend it into a "U" shape. Jump A and B and with ignition on (watch the engine light)and engine off it should flash a 12 (one flash short pause and then two flashes followed by long pause then 12 again) After it flashes 12 three times in should flash any codes stored in the computer. Once it flashes all the trouble codes it will flash 12 again to tell you its finished. Jim |

All the unit does is plug in, jump A to B, and you still have to rely on the engine light for pulses. Thanks for help, what fun to learn all this new stuff :thumbs: tt |
