SPEEDOMETER
ABS actuator and electric unit (control unit) provides a vehicle speed signal to the unified meter and A/C amp.
with CAN communication line. After unified meter and A/C amp. received the vehicle speed signal, it changes
the signal to 8 pulse signal and provides the 8 pulse signal to the combination meter for the speedometer.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm).
ECM provides an engine speed signal to unified meter and A/C amp. with CAN communication line. Unified
meter and A/C amp. provides an engine speed signal to combination meter for tachometer with communica-
tion line between unified meter and A/C amp. and combination meter.
LOW WATER TEMPERATURE INDICATOR LAMP, HIGH WATER TEMPERATURE WARNING
LAMP
ECM converts water temperature signal from water temperature sensor into data and transmits the data to uni-
fied meter and A/C amp. with CAN communication line. Unified meter and A/C amp. transmit the received
water temperature signal to the combination meter with communication line between unified meter and A/C
amp. and combination meter. Combination meter turns on/off low water temperature indicator lamp or high
water temperature warning lamp through the received water temperature signal.
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 unified meter and A/C amp. terminal 36

through the fuel level sensor unit and fuel pump terminals 5 and 2

to unified meter and A/C amp. terminal 28 for the fuel gauge.
Unified meter and A/C amp. provides a fuel level signal to combination meter for fuel gauge with communica-
tion line between unified meter and A/C amp. and combination meter.

5. Press 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 and shift indicator illuminate, and simultaneously the low-fuel warn-
ing lamp indicator illuminates. At this time, the unified meter control unit is turned to diagnosis mode.
NOTE:

7. Each meter activates during pressing odo/trip meter switch. (At this time, the low-fuel warning lamp goes
off, low water temperature indicator lamp and high water temperature warning lamp goes on.)
NOTE:
The figure is reference.
CONSULT-II FunctionBKS001S5
Refer to DI-29, "CONSULT-II Function (METER A/C AMP)" in “UNIFIED METER AND A/C AMP”.

PRELIMINARY CHECK
1. CHECK SELF-DIAGNOSIS RESULT OF UNIFIED METER AND A/C AMP.
1. Start engine.
2. Select “METER A/C AMP” on COSULT-II, and perform self-diagnosis of unified meter and A/C amp. Refer
to DI-29, "
CONSULT-II Function (METER A/C AMP)"
3. After erasing the self-diagnosis result, perform self-diagnosis again.
Self-diagnosis results content
No malfunction detected >> GO TO 2.
Malfuction detected >> GO TO DI-17, "
SYMPTOM CHART 2" .
2. CHECK WARNING LAMP ILLUMINATION
1. Turn ignition switch ON.
2. Make sure warninig lamps (such as malfunction indicator lamp and oil pressure warning lamp) illuminate.
Do warninig lamps illuminate?
OK >> GO TO 3.
NG >> Check ignition power supply system of combination meter.
3. CHECK SELF-DIAGNOSIS OPERATION OF COMBINATION METER
Perform combination meter self-diagnosis. Refer to DI-13, "
OPERATION PROCEDURE" .
Does self-diagnosis function operate?
OK >> GO TO 4.
NG >> Check battery power supply of combinatiom meter and ground circuit.
4. CHECK COMBINATION METER CIRCUIT
Check indication of each meter/gauge in self-diagnosis mode.
OK or NG
OK >> GO TO 5
NG >> Replace combination meter.
5. CHECK LOW-FUEL WARNING LAMP ILLUMINATION
While checking low-fuel warning lamp check, confirm illumination of low-fuel warning lamp.
Does low
-fuel warning lamp illuminate (while not pushing odo/trip meter switch)?
YES >> GO TO 6.
NO >> Replace combination meter.
Condition of odo/trip meter switch Low-fuel warning lamp
Pressed Does not illuminate.
Released Illuminates.

6. CHECK LOW WATER TEMPERATURE INDICATOR LAMP AND HIGH WATER TEMPERATURE
WARNING LAMP ILLUMINATION
When checking low water temperature indicator lamp and high water temperature warning lamp, make sure
that the indicator lamp and warning lamp illuminate.
Do low water temperature indicator lamp and high water temperature warning lamp illuminate (while pushing
odo/trip meter switch)?
YES >> GO TO 7.
NO >>

Replace combination meter when both of them do not illuminate.

Replace bulb when only low water temperature indicator lamp do not illuminate.

Replace combination meter when only high water temperature warning lamp do not illuminate.
7. CHECK SEGMENTS
Check odo/trip meter segment and shift indicator segment. Refer to DI-13, "
OPERATION PROCEDURE"
Do all segments illuminate?
YES >> GO TO .
NO >>

When the condition of odo/trip meter is irregular, replace odo/trip meter. Perform diagnosis for
the combination meter again. If the segment still does not illuminate, replace entire combination
meter.

When the condition of shift position indicator is irregular, replace combination meter.
Condition of odo/trip meter switchLow water temperature indicator lamp and
