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.
