Need help with DTC's U1000 and B1025
I can't figure out what these are all about. Should I clear them and see if they ever come back? Could these have been caused by the battery in the truck going dead at some point? I have run it dead many times with my large power inverter for the full size PC I have installed in the truck. Sometimes I forget to turn off the inverter, and the standby (mosfet bias) current will drain the battery overnight.

I just wish I knew what they are for... Recently I have noticed that the dinging sound when you leave the keys in the truck, or when the low fuel light comes on, or when the blinker stays on too long etc is barely audible. It used to be loud. I don't really mind it, but I was wondering what happened to it. Is there some way to set that? I have the W/T package truck so it doesn't have the fancy radio with the builtin controls for convenience features etc like the LS trucks have. My radio is factory AM/FM only. No cassette, no CD. I use a RF modulator (FM type) like the mp3 players use to play the audio from my computer into my radio on 88.7fm and that works just fine, mp3's, movies, etc all sound fine that way without having to change the factory radio.
