System DescriptionEKS00L8E
UNIFIED METER CONTROL UNIT
lSpeedometer, 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.
lWarning lamp and indicator lamp are controlled by signals drawn from each unit with CAN communication
and components connected directly to the combination meter.
lOdo/trip meter display is included in the combination meter, which displays odometer, trip-meter, vehicle
information (trip computer, engine oil maintenance information)
*and A/T position*.
*: Vehicles with each system only.
lClock display is included in the combination meter, which displays current time, ambient air temperature*
and 4WD indicator*.
*: Vehicles with each system only.
lUnified meter control unit corresponds a CONSULT-II function (self-diagnosis results and data monitor).
lThe following items can be checked during self-diagnosis mode.
–Sweep of gauges pointer
–Present gauge values
–Odo/trip meter display and clock display segments
–Condition of warning lamps/indicator lamps controlled by unified meter control unit
–Battery voltage
–Driver's seat belt buckle switch status
–CPU status of unified meter control unit
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
lthrough 10A fuse [No.19, located in the fuse block (J/B)]
lto combination meter terminal 3.
With the ignition switch in the ON or START position, power is supplied
lthrough 10A fuse [No.14, located in the fuse block (J/B)]
lto combination meter terminal 16.
Ground is supplied
lto combination meter terminals 13 and 23
lthrough grounds M21, M80 and M83.
SPEEDOMETER
The speedometer indicates the vehicle speed.
lABS actuator and electric unit (control unit) converses a pulse signal from wheel sensor to vehicle speed
signal, and transmits vehicle speed signal to combination meter with CAN communication.
lCombination meter converses the vehicle speed signal to angle signal, and commands to speedometer.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm).
lECM converses a signal from crank position sensor to engine speed signal, and transmits to combination
meter with CAN communication.
lCombination meter converses the engine speed signal to angle signal, and commands to tachometer.
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
lECM converses a signal from water temperature sensor to engine coolant temperature signal, and trans-
mits to combination meter with CAN communication.
lCombination meter converses the engine coolant temperature signal to angle signal, and commands to
water temperature gauge.

10. Remove crankshaft gear.
lRemove crankshaft gear (1) with the following procedure
(4WD models).
a. Make sure that No.1 piston is TDC on its compression stroke.
b. Turn the idler sub gear (3) counterclockwise with snap ring plier
(B) or suitable tool for aligning idler sub gear (3) and idler main
gear (2).
lIf idler gear rotates, hold the flat faces on balancer drive shaft
front end (4).
c. Install internal mechanism securing bolt and plate (Service part:
13012 EB30A and 13013 EB30A) (A) and tighten to the speci-
fied torque.
CAUTION:
lDo not loosen idler gear mounting bolt (5).
lOnly use the genuine internal mechanism securing bolt
and plate (A), or the idler gear (2) and (3) will be damaged.
lDo not remove internal mechanism securing bolt and
plate (A) from idler gear (2) and (3) until crankshaft gear
(1) and all of the parts in connection have been installed.
lIf internal mechanism securing bolt and plate (A) is not
installed, internal mechanism of idler gear (2) and (3) will
disengage after crankshaft gear (1) is removed. This will prohibit the balancer unit from being
reusable.
