mine lights up on an intermittent basis. it is too minor for me to bother
to do anything about it.

not that i know of.

press the "outside temp" while the "off" button is depressed and read
off the value displayed. this puts the system into diagnostic mode.
i think that if you check in the archives someone has posted all the
CC failure codes. sounds like there's a fault in there.

this fix involves replacing the entire dash. lots of v8s have replaced
odometers because of this. lots of $$$.

i get about 380 miles per tank before i decide to fill up, which i can
stretch to 400 if i want to risk running out. this is mostly highway
driving. the computer sez 23.5-24.5 mpg typically, but is at least
10-15% off. there are a row of dip switches behind the dash to fine
tune this readout, btw, but it's too much hassle for me to rip
everything out. i got a 10% improvement in mileage after the OXS
