System DescriptionEKS00EGZ
UNIFIED CONTROL METER

Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the
unified meter control unit, which is built into the combination meter.

Digital meter is adopted for odo/trip meter.*
*The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.

Odo/trip meter segments can be checked in diagnosis mode.

Meter/gauge can be checked in diagnosis mode.
HOW TO CHANGE THE DISPLAY FOR ODO/TRIP METER

The vehicle speed signal and the memory signals from the meter memory circuit are processed by the
combination meter and the mileage is displayed.

Ambient temperature indicator indicates signal from ambient sensor processed by combination meter.

Depressing the odo/trip meter switch toggles the mode in the following order.

The odo/trip meter display mode toggling and trip display resetting can be identified by the amount of time
that elapses from pressing the odo/trip meter switch to releasing it.

When resetting with trip A displayed, only trip A display is reset (The same way for trip B).
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times

through 10A fuse [No. 28, located in the fuse block (J/B)]

to combination meter terminal 1.
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 11, located in the fuse block (J/B)]

to combination meter terminals 2.
Ground is supplied

to combination meter terminals 21

through grounds M27 and M70.
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
ECM provides an engine coolant temperature signal to combination meter for water temperature gauge with
CAN communication line.

TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm).
ECM provides an engine speed signal to combination meter for tachometer with CAN communication line.
SPEEDOMETER
ESP/TCS/ABS control unit (with ESP) or ABS actuator and electric unit (without ESP) provides a vehicle
speed signal to the combination meter for the speedometer with CAN communication line.
FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable ground signal supplied

from grounds B8 and B18 (LHD models)

from grounds B107 and B119 (RHD models)

through terminal 1 and 4 of the fuel level sensor unit

through terminal 3 and 1 of the sub fuel level sensor unit and

to combination meter terminal 8 for the fuel gauge.
AMBIENT TEMPERATURE INDICATOR
The ambient temperature is indicated by the signal from ambient sensor.
Combination meter inputs voltage conversed from resistance which ambient sensor detects.
Indication range is between −30 and 55 °C (−22 and 131 °F). When ambient air temperature is less than −30
°C (−22 °F) or more than 55 °C (131 °F), display shows “---°C”. When indicated temperature becomes less
than 3 °C (37 °F), ambient temperature indicator flashes as a sign of warning.
Without Auto A/C
Power is supplied

through combination meter terminal 27

to ambient sensor terminal 1.
Ground is supplied

to combination meter terminal 28

through ambient sensor terminal 2.
Signal is supplied

through ambient sensor terminal 1

to combination meter terminal 27.
With Auto A/C
Power is supplied

through auto amp terminal 9

to ambient sensor terminal 1.
Ground is supplied

to combination meter terminal 28 and auto amp terminal 24

through ambient sensor terminal 2.
And combination meter receives ambient sensor signal from ambient sensor

through ambient sensor terminal 1

to combination meter terminal 27.
NOTE:
Combination meter distinguishes whether or not the combination meter terminal 29 receives voltage (auto A/C
recognition signal) from auto amp terminal 28. If the terminal receives, combination meter discerns as auto A/
C.
Indication When Turning Ignition Switch OFF

In a case that temperature detected by ambient sensor is higher than indicated temperature before turn-
ing ignition switch OFF.
–In a case of more than 3.5 hours after turning ignition switch OFF, temperature detected by ambient sen-
sor is indicated when turning ignition switch ON.

DI-6
COMBINATION METERS

–In a case of less then 3.5 hours after turning ignition switch OFF, temperature at the time of turning ignition
switch off is indicated.

In a case that temperature detected by ambient sensor is lower than indicated temperature before turning
ignition switch OFF.
–Temperature detected by ambient sensor is indicated when turning ignition switch ON.
Indication During Running
Though temperature detected by ambient sensor temporarily changed, indicating temperature continentally
indicates.

In a case that temperature detected by ambient sensor is higher than indicated temperature.
–If vehicle speed is more than 20 km/h (13 MPH), elevation of indicating temperature is limited according to
the speed until temperature detected by ambient sensor is indicated.
NOTE:
Vehicle speed 20 km/h (13 MPH): 256 sec., 25 km/h (16 MPH): 238 sec., 35 km/h (22 MPH): 200 sec., 50
km/h (31 MPH): 144 sec., 65 km/h (40 MPH): 88 sec., more than 80 km/h (50 MPH): 32 sec.
–If vehicle speed is more than 20 km/h (13 MPH), and that temperature detected by ambient sensor
becomes 8 °C (46 °F) more than indicating temperature, indicating temperature will be elevated unit the
degree becomes same as temperature detected by ambient sensor with limiting elevation of indicating
temperature 1 °C par a minute.
–If vehicle speed is less than 20 km/h (13 MPH), indicating temperature is continually kept.

In a case that temperature detected by ambient sensor is lower than indicated temperature.
–Temperature detected by ambient sensor is indicated during running.
CAN CommunicationEKS00EH0
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

Meter/Gauges Operation and Odo/Trip MeterEKS00EH7
SELF-DIAGNOSIS FUNCTION

Odo/trip meter segment operation can be checked in self-diagnosis mode.

Meters/gauges can be checked in self-diagnosis mode.
HOW TO ALTERNATE DIAGNOSIS MODE
1. Turn ignition switch ON, and switch the odo/trip meter to “trip A” or “trip B”.
NOTE:
If the diagnosis function is activated with the trip meter A displayed, the mileage on the trip meter A will
indicate 0.0 miles, but the actual trip mileage will be retained (The same way for trip B).
2. Turn ignition switch OFF.
3. While pushing the odo/trip meter switch, turn ignition switch ON again.
4. Make sure that the trip meter displays “0.0”.
5. Push the odo/trip meter switch at least 3 times (Within 7 seconds after the ignition switch is turned ON).
6. All the segments on the odo/trip meter illuminate, and simultaneously the low-fuel warning lamp indicator
illuminates. At this time, the unified meter control unit is turned to diagnosis mode.
NOTE:
If any of the segments is not displayed, replace the combination
meter.
