My 06 CTS worked just fine three days ago. Then this afternoon I get in it, start it, back out of the driveway and find that I have no speedometer, no odometer, no 1-2-3-4-5 (in the odometer box when shifting manually), and that other information relying on speed and distance data is incorrect (avg mpg, instant mpg, avg speed). The rest of the car and guages are working just fine (and no CEL).
I'm thinking that there's some output data from the transmission that has been interrupted by a damaged wire, damaged connection, blown fuse, or...? Is there some "black box" that has failed? I tried restarting the engine several times; I tried going back and forth from MPH to KPH--no dice.
I have not yet started chasing this down--have any of you experienced this problem? Does anyone have some suggestions about where to start looking? (I have the full set of shop manuals.)
Thanking you in advance for your assistance!
