I was playing with my '06 and tried to go into the CO settings from memory. I held the two buttons while turning on the key until 'diag' displayed and then released the buttons. Next I held the two buttons for a couple more seconds and then released them. Now the display showed d:1 (I think that was the start), from there if I hit either button it would scroll through a list of d: settings. Some were set to numbers, others were set to 'off'. a couple as you pass over them, cause what sounds like the fuel pump to run.
Anyone know what this mode is and what those settings (or whatever) are?
