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.
