Unified Control Meter System Description
UNIFIED CONTROL METER
Speedometer, odo/trip meter, tachometer, fuel gauge and water
temperature gauge are controlled totally by unified meter control
unit.
Meter/gauge Operation and Odo/Trip Meter
Segment Check in Diagnosis Mode
DIAGNOSIS FUNCTION
lOdo/trip meter segment can be checked in diagnosis mode.
lMeters/gauges can be checked in diagnosis mode.
HOW TO ALTERNATE DIAGNOSIS MODE
1. Turn ignition switch to ON and change odo/trip meter to
``TRIP A'' or ``TRIP B''.
2. Turn ignition switch to OFF.
3. Turn ignition switch to ON when pushing odo/trip meter
switch.
4. Confirm that trip meter indicates ``000.0''.
5. Push odo/trip meter switch more than three times within 5
seconds.
6. All odo/trip meter segments should be turned on.
NOTE: If some segments are not turned on, unified meter
control unit should be replaced.
At this point, the unified control meter is turned to diagnosis
mode.
7. Push odo/trip meter switch. Indication of each meter/gauge
should be as shown left during pushing odo/trip meter switch
if it is no malfunctioning.
NOTE: It takes about 1 minute for indication of fuel gauge
to become stable.

Flexible Print Circuit (FPC) (Models with
Tachometer)
Tachometer, fuel gauge and water temperature gauge are con-
nected with unified meter control unit (speedometer) by Flexible
Print Circuit (FPC) connector. When replace or remove and
install unified control unit (speedometer), disconnect and con-
nect FPC connector according to the following steps.
DISCONNECT
1. Open connector cover.
2. Release connector lock by holding both ends of it and pull-
ing it up.
3. Disconnect FPC by pulling it up.
CONNECT
1. Insert FPC into connector and lock connector pushing FPC
downward.
2. Check secure connection of FPC.
3. Check continuity of check land terminals for secure connec-
tion of FPC.
Resistance: 0W
4. Close connector cover.
