Garlicdude Posted June 19, 2004 Report Share Posted June 19, 2004 Standard procedure is to disconnect the battery when doing anything electrical that might get fried. I would assume that you loose radio presets and the time, but what other things do you loose if any? Link to comment Share on other sites More sharing options...
Scotty Posted June 19, 2004 Report Share Posted June 19, 2004 Always disconnect the negative terminal first. Yes you will lose the radio presets, clock setting, and the PCM will be reset and will go through a relearn procedure. You will lose any history codes, any current codes will probably be reset on start up. A code will be set because you disconnected the battery. That is about all that I think it will affect.

bigfoo Posted June 19, 2004 Report Share Posted June 19, 2004 I didn't lose any settings at all when I pulled the battery on my 99, and it was pulled for many hours.. even the radio presets were still there .. Link to comment Share on other sites More sharing options...
Garlicdude Posted June 19, 2004 Author Report Share Posted June 19, 2004 bigfoo, Sounds like flash memory? I wonder if the 98's work like that? Link to comment Share on other sites More sharing options...
bigfoo Posted June 19, 2004 Report Share Posted June 19, 2004 I would think so.. there isn't much difference in between 98 and 99.. I think the major difference was between 96 and 97 IIRC.. I'm sure someone will chime in on this Link to comment Share on other sites More sharing options...
brmurph Posted June 19, 2004 Report Share Posted June 19, 2004 My 98 Concours keeps all of the radio settings as well. Link to comment Share on other sites More sharing options...
Phillip Posted June 19, 2004 Report Share Posted June 19, 2004 I disconnected the battery on my '96 STS the other day. I do not have a comprehensive list of items but many reset. The clock, trip odometer, mileage, run time and most other computer settings were reset. Interestingly enough, the radio presets were retained. I had to reload the CD magazine. Overall, it wasn't really a major pain. Link to comment Share on other sites More sharing options...
JimD Posted June 20, 2004 Report Share Posted June 20, 2004 To the best of my knowledge, with a '98 STS, the only thing lost is XX GAL FUEL USED plus anything that is based on that data....

Phillip Posted June 21, 2004 Report Share Posted June 21, 2004 Yaa, we're missing a few features I suppose, but I think I'll keep 'er for a while yet. Link to comment Share on other sites More sharing options...
