[After reading through the Electronic Instrument Display manual, I have
dete=
rmined that my dash isn't quite working right. According to the manual
ther=
e is an electronic eye that detect light natural light levels and adjusts
t=
he display automatically. When it detects low light levels it
automatically=
 dims the dash and if you start the car in the dark it will flash a green
e=
mblem on the dash to remind you to turn on your headlights. But in my case
=
it does this every time, and I've always thought my dash was too dim in
day=
light. It seems to me that the electronic eye must not be functioning
prope=
rly and it "thinks" it's dark out and id dimming the dash and tripping the
=
warning light. I'd really like to get this feature working right. Anybody
e=
ver had this problem? Anybody willing to suggest some things to check to
he=
lp troubleshoot this? Also has anybody successfully calibrated their fuel
r=
ange using the directions in the manual? Is it really as easy as it
appears?

TIA,

I've been working on this coupe[for sale] with digital dash in my garage.
 I had supposed the annoying green flashing light that comes on was a
problem I had to troubleshoot.  Thanks to your email, looks like there is
no problem.  That explains why the light goes away when I drive it outside
- I did not make the connection, at first.

Sorry, I'm not able to help get yours functioning right.

[OK, since nobody seems to have any troubleshooting tips, can the
"electroni=
c eye" be overridden? Could it be removed/disconnected and have the system
=
say in daylight mode all the time? I could then dim the dash manually with
=
the rheostat (sp?). Anybody?]

I would think you could disable this IMO annoying feature.  I would think
the eye provides an on or an off..perhaps short or disconnect to disable.
