ronstone Posted January 17, 2005 Report Share Posted January 17, 2005 I've recently reset the error codes in my 96 Concours, but here are the history codes I have. Can anyone recite the meanings off the top of their heads? PC0325 PC0603 IP1552 IP2144 PZ1970 PZ1971 PZ1982 PZ2470 PZ2471 PZ2472 PZ2473 PZ2476 PZ2255 PZ2152 That's an awful lot. I never had these a few months ago when I checked. I get a Service Engine Soon light every now and then and to check my Emissions warning. Thanks, Ron Link to comment Share on other sites More sharing options...

WATCH HOW THIS CABLE COMES APART SO YOU CAN ASSEMBLE IT AGAIN, THERE IS A LUG made of LEAD, BRASS WASHER and LONG BOLT. Corrosion gets into this connection, white acidy stuff (protect your eyes and skin). Do the same with the negative (but there is only one wire there). I just did mine last night. Go to your local auto parts store and buy battery terminal spray and spray all the connectors when you get them apart to clear the oxidation and corrosion. I also wire brushed my connections. That is where I would start, your codes will be cleared at that point and you can start over knowing you are making a good connection at the battery. If you see any (-) grounds to the frame you could remove and clean them also. Mike Link to comment Share on other sites More sharing options...
adallak Posted January 17, 2005 Report Share Posted January 17, 2005 The longer the code list the better since it clearly idicates bad cable or connections. Follow Scotty's detailed instructions and you'll be fine. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...

Julio Posted January 17, 2005 Report Share Posted January 17, 2005 It is improtant when terminating the positive cable that the cables do not swivel, it is an indication of the positive lug bottoming out rather than fastening cables. This will cause the auto to shut off abruptly, an indication that that your + terminal lug is loose prior to the complete shut off is the raido resetting. clock changing time ect..
