Jim, am I right in thinking that Deven pulling the fuse would cause the P0603 code?

There are a whole bunch of codes listed for the GEM functions. Since he has none of these does anyone have an idea of what would cause his problems without throwing a code? I am thinking that the GEM is getting a normal signal from a sensor that keeps the Accessory Delay Relay closed. The key chime would be a sympom of that.

Deven, is the chime you were getting the one for the key in the ignition, or for the key ON with the door open?
