System Description EKS0039A
UNIFIED CONTROL METER
q Speedometer, odo/trip meter, tachometer (if equipped), fuel gauge and water temperature gauge are con-
trolled by the unified meter control unit built-in combination meter.
q Digital meter is adopted for odo/trip meter.*
*The record of the odometer is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.
q Odo/trip meter segment can be checked in diagnosis mode.
q Meter/gauge can be checked in diagnosis mode.
HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER (WITHOUT TRIP COMPUTER)
NOTE:
Turn ignition switch to the ON position to operate odo/trip meter.
SEL253V
HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER (WITH TRIP COMPUTER)
NOTE:
Turn ignition switch to the ON position to operate odo/trip meter.
SEL175W
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times:
DI-4
METERS AND GAUGES
q through 10A fuse [No. 12, located in the fuse block (J/B)]
q to combination meter terminal 25 (without tachometer), or 42 (QG18DE with tachometer), or 13 A
(QR25DE).
With the ignition switch in the ON or START position, power is supplied:
q through 10A fuse [No. 30, located in the fuse block (J/B)] B
q to combination meter terminal 26 and 20 (without tachometer), or 41 and 6 (QG18DE with tachometer), or
14 and 7 (QR25DE).
Ground is supplied: C
q to combination meter terminal 27 (without tachometer), or 48 (QG18DE with tachometer), or 12
(QR25DE)
q through body grounds M28 and M54. D
q to combination meter terminal 31 (without tachometer), or 45 (QG18DE with tachometer), or 8 (QR25DE)
q through body grounds B19 and B13.
E
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
ECM provides a water temperature signal to combination meter for water temperature gauge with CAN com- F
munication line.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm). G
ECM provides an engine speed signal to combination meter for tachometer with CAN communication line.
FUEL GAUGE
H
The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable ground signal supplied:
q to combination meter terminal 30 (without tachometer), or 44 (QG18DE with tachometer), or 21
(QR25DE) for the fuel gauge I
q from terminal 2 of the fuel level sensor unit and fuel pump
q through terminal 5 of the fuel level sensor unit and fuel pump, and
J
q through body grounds B19 and B13.
SPEEDOMETER
The combination meter receives a voltage signal from the vehicle speed sensor for the speedometer. DI
The voltage is supplied:
q to combination meter terminal 29 (without tachometer), or 47 (QG18DE with tachometer), or 17
(QR25DE) for the speedometer L
q from terminal 1 (with QG18DE), or terminal + (with QR25DE) of the vehicle speed sensor.
The speedometer converts the voltage into the vehicle speed displayed.

Meter/Gauge Operation and Odo/Trip Meter Segment Check in Diagnosis Mode
EKS0039E A
SELF-DIAGNOSIS FUNCTION
q Odo/trip meter segment can be checked in diagnosis mode.
q Meters/gauges can be checked in diagnosis mode. B
HOW TO ALTERNATE DIAGNOSIS MODE
1. Turn ignition switch to ON and change odo/trip meter to "TRIP
A" or "TRIP B". C
2. Turn ignition switch to OFF.
3. Turn ignition switch to ON when pushing odo/trip meter switch.
D
4. Release odo/trip meter switch 1 second after ignition switch is
turned ON.
5. Push odo/trip meter switch three times within 7 seconds.
E
6. All odo/trip meter segments should be turned on.
NOTE:
If some segments are not turned on, combination meter should
be replaced. F
At this point, the unified control meter is turned to diagnosis
mode.
G

I
WKIA1120E
7. Push odo/trip meter switch. Indication of each meter/gauge J
should be as shown in figure during pushing odo/trip meter
switch.
NOTE: DI
It takes a few seconds for indication of fuel gauge and water
temperature gauge to become stable.
8. Turn ignition switch to OFF or start engine to cancel diagnosis L
mode.
