Switch modes with following procedure.
 When trip transfer switch is pressed, trip meter display changes.
 If trip reset switch is pressed for 1 second or more while “trip A” is displayed, only “trip A” is reset.
NOTE:
The record of the odo meter is kept even if the battery cable is dis-
connected. The record of the trip meter is erased when the battery
cable is disconnected.
COMBINATION METER ILLUMINATION CONTROL
Daytime Mode
When ignition switch is turned ON, combination meter il lumination is turned ON by unified meter control unit.
Nighttime Mode
 Unified meter control unit is transferred to nighttime mode, with ignitio\
n switch turned ON and position light
request signal from BCM with CAN communication.
 When nighttime mode, illumination c ontrol switch illumination turns
ON by unified meter control unit. Each illumination is controlled by
unified meter control unit.
 Each illumination can be adjusted to 16 step by illumination control switch in nighttime mode.
NOTE:
For further details of illumination circuit, refer to LT-169, "
System

3. Turn ignition switch ON while pressing trip transfer switch and trip reset switch at the same time.
4. After ignition switch is turned ON, release trip transfer switch and trip reset switch (within 7 seconds after the ignition switch is
turned ON).
5. All the segments on the odo/trip meter, A/T indi cator and ICC system display illuminates, and simulta-
neously the low-fuel warning lamp indicator illuminates. At this time, the unified meter control unit is turned
to self-diagnosis mode.
NOTE:
 Check odo/trip meter switch and combination meter power supply and ground circuit when self-diagno-
sis mode of combination meter does not start. Replace combination meter if the results of the check are
normal.
 If any of the segments are not disp layed, replace combination meter.
6. Each meter/gauge activates during pressing trip reset switch. (Then low-fuel warning lamp turns OFF.)
NOTE:
 If any of the meters/gauges are not activated, replace thecombination meter.
