My Autocheck display seems to have completely stopped functioning 
I don't get the on-start brake-check, the speed warning doesn't work, and neither can I get it to cycle through any of the warning symbols by pressing the left stalk on the instrument cluster. The trip computer LCD is working fine however.
I'm inclined to think it's not just blown bulbs seeing as the speed check beep doesn't work either.
Anyone got any suggestions?
