POSSIBLE CAUSE
The fuse has blown.
No ACC position on vehicle
ignition.
The computer chip in the unit is
not functioning normally.
The unit is not connected to the
parking brake detection switch.
The parking brake is not
engaged.
The unit is in a location where
temperature is low.
SOLUTION
After checking for short circuits
in the cables, replace the fuse
with one having the same rating.
Connect the same cable to the
ignition as the battery cable.
Press the reset button on the unit
(See page 3).
Make proper connections
according to "Connection" (See

If the temperature of the monitor
unit drops, the screen may
appear darker when power is first
turned on due to the
characteristics of a liquid crystal
panel. Wait a while after turning
power on for the temperature to
rise. Normal brightness will
return.
