PFP:24814
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.

WHEEL HUB
3. Put alignment mark on disc rotor and wheel hub and bearing
assembly, then remove disc rotor.
— For 4WD models —
lRemove cotter pin, then remove lock nut from drive shaft. Refer toFA X - 7 , "Removal and Installation".
lRemove drive shaft from wheel hub and bearing assembly. Refer toFAX-5, "Removal and Installation".
4. Remove wheel sensor from wheel hub and bearing assembly. Refer toBRC-37, "
Removal and Installa-
tion".
lInspect the wheel sensor O-ring, replace the wheel sensor assembly if damaged.
lClean the wheel sensor hole and mounting surface with a suitable brake cleaner and clean lint-free
shop rag. Be careful that dirt and debris do not enter the axle bearing area.
lApply a coat of suitable grease to the wheel sensor O-ring and mounting hole.
CAUTION:
Do not pull on the ABS sensor harness.
5. Remove wheel hub and bearing assembly bolts.
6. Remove splash guard and wheel hub and bearing assembly from steering knuckle.
lCarefully remove wheel sensor and harness through hole in splash guard.
INSPECTION AFTER REMOVAL
Check for deformity, cracks and damage on each part and replace if necessary.
INSTALLATION
Installation is in the reverse order of removal.
lUse new bolts when installing the wheel hub and bearing assembly.
lWhen installing disc rotor on wheel hub and bearing assembly,
position the disc rotor according to alignment mark.
(When not using the alignment mark, refer toBR-26, "
Removal
and Installation of Brake Caliper Assembly".)
lWhen installing wheel and tire, refer toWT-5, "Rotation".

Check front suspension parts for excessive play, cracks, wear and
other damage.
lShake each front wheel to check for excessive play.
If looseness is noted, inspect wheel bearing end play, then
check ball joint end play. Refer toFSU-15, "
Inspection".
lMake sure that the cotter pin is inserted in drive shaft end (4WD
models only).
lRetighten all nuts and bolts to the specified torque.
lCheck shock absorber for oil leakage and other damage.
lCheck suspension ball joint for grease leakage and ball joint
dust cover for cracks and other damage.
Front Wheel AlignmentEES002KN
PRELIMINARY INSPECTION
WARNING:
Always adjust the alignment with the vehicle on a flat surface.
NOTE:
If alignment is out of specification, inspect and replace any damaged or worn rear suspension parts before
making any adjustments.
1. Check and adjust the wheel alignment with the vehicle under unladen conditions. “Unladen conditions”
means that the fuel, coolant, and lubricant are full; and that the spare tire, jack, hand tools and mats are in
their designated positions.
2. Check the tires for incorrect air pressure and excessive wear.
3. Check the wheels for run out and damage. Refer toWT-3, "
Inspection".
4. Check the wheel bearing axial end play. Refer toFA X - 5 , "
WHEEL BEARING INSPECTION".
5. Check the shock absorbers for leaks or damage.
6. Check each mounting point of the suspension components for any excessive looseness or damage.
7. Check each link, arm, and the rear suspension member for any damage.
8. Check the vehicle height. Refer toFSU-21, "
Wheelarch Height (Unladen*1)". Suspension component torques : Refer toFSU-6,
"Components".SMA525A

NOTE:
lFor “A/T”, “UNKWN” is displayed on “METER/M&A”, “ICC/e4WD” and “AWD/4WD”. But put a check
mark to “METER/M&A” because “UNKWN” is listed on the column of reception diagnosis of the check
