The only GM reference that I could find for this code was for the fuel pump control circuit, nothing about the passkey system. What problems are you experiencing? I asked a moderator to move this out of the 2000+ section to here. You'll get better exposure and responses if you post in the right section.

I moved this to the 1992 - 1999 section for you

I also did a search on that code and didn't really find much, only two other topics, and neither one had much info in them

Please see your other post for a possible cause of the electrical system.
