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.
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
ECM provides an engine coolant temperature signal to unified meter and A/C amp. with CAN communication
line. Unified meter and A/C amp. provides a engine coolant temperature signal to combination meter for water
temperature gauge with communication line between unified meter and A/C amp. and combination meter.
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 (main) terminals 5 and 2, and
through the fuel level sensor unit (sub) terminals 2 and 1
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.

Trouble phenomenon Possible cause
Indication is irregular for the speedometer and odo/trip meter. Refer to DI-20, "
Vehicle Speed Signal Inspection" .
Tachometer indication is malfunction. Refer to DI-21, "
Engine Speed Signal Inspection" .
Water temperature gauge indication is malfunction. Refer to DI-21, "
Engine Coolant Temperature Signal Inspection" .

A/T Indicator Is Malfunction" .
Illumination control does not operate. Refer to
DI-24, "
Odo/Trip Meter and Illumination Control Switch
Inspection" .
Displayed item [Code] Inspection contents Possible cause
CAN COMM CIRC [U1000] Inspect the CAN communication. Refer to
DI-34, "
DTC [U1000] CAN Communication Circuit" .
CAUTION:
Even when there is no malfunction on CAN communica-
tion system, malfunction may be misinterpreted when bat-
tery has low voltage (when maintaining 7 - 8 V for about 2
seconds) or 10A fuse [No. 19, located in the fuse block (J/
B)] is disconnected.
METER COMM CIRC [B2202] Inspect the communication line
between combination meter and
unified meter and A/C amp. Refer to
DI-34, "
DTC [B2202] Meter Communication Circuit" .
VEHICLE SPEED CIRC [B2205] Inspect the vehicle speed input
signal. Refer to
DI-37, "
DTC [B2205] Vehicle Speed Circuit" .
CAUTION:
Even when there is no malfunction on speed signal sys-
tem, malfunction may be misinterpreted when battery has
low voltage (when maintaining 7 - 8 V for about 2 seconds).

Engine Speed Signal Inspection AKS005MW
Symptom: Tachometer indication is malfunction.
1. CHECK UNIFIED METER AND A/C AMP. OUTPUT SIGNAL
1. Start an engine and select “METER A/C AMP” on CONSULT-II.
2. Using “TACHO METER” on “DATA MONITOR”, compare the value of “DATA MONITOR” with tachometer pointer of combina-
tion meter.
OK or NG
OK >> GO TO 2.
NG >> Replace combination meter.
2. CHECK UNIFIED METER AND A/C AMP. INPUT SIGNAL
1. Select “ENGINE” on CONSULT-II.
2. Using “ENG SPEED” on “DATA MONITOR”, print out the CON- SULT-II screen when the engine is idling.
3. Select “METER A/C AMP” on CONSULT-II.
4. Using “TACHO METER” on “DATA MONITOR”, compare the value of “DATA MONITOR” of the idling speed with that of the
“ENG SPEED”.
OK or NG
OK >> Perform ECM self-diagnosis. Refer to EC-132, "CON-
SULT-II Function (ENGINE)" (for VQ35DE) or EC-822,
"CONSULT-II Function (ENGINE)" (for VK45DE).
NG >> Replace unified meter and A/C amp. Refer to DI-37,
"Removal and Installation of Unified Meter and A/C Amp." .
Engine Coolant Temperature Signal InspectionAKS005MX
Symptom: Water temperature gauge indication is malfunction.
1. CHECK UNIFIED METER AND A/C AMP. INPUT SIGNAL
1. Start engine and select “METER A/C AMP” on CONSULT-II.
2. Using “W TEMP METER” on “DATA MONITOR”, compare the value of “DATA MONITOR” with water temperature gauge
pointer of combination meter.

UNIFIED METER AND A/C AMP
Revision: 2005 July 2005 FX
UNIFIED METER AND A/C AMPPFP:27760
System DescriptionAKS005N8
For the unified meter and A/C amp., the signal required for controlling the combination meter are inte-
grated in the A/C auto amp.
Unified meter and A/C amp. controls each operation for A/C auto amp. For information regarding A/C con-
trol, refer to AT C - 3 0 , "
AIR CONDITIONER CONTROL" in ATC section.
Unified meter and A/C amp. inputs necessary information for combination meter from each unit by CAN
communication and so on.
And unified meter and A/C amp. outputs these signals using communication line (TX, RX) between unified
meter and A/C amp. and combination meter.
The signals required for the distance to empty (DTE) display are centralized in the unified meter and A/C
amp., converted into data, and sent to the display unit (without NAVI) display control unit (with NAVI) using
CAN communication.
Other input signals are also sent to the ECM, TCM, AWD control unit, BCM, display unit (without NAVI)
and display control unit (with NAVI) using CAN communication.
The unified meter and A/C amp. correspond a CONSULT-II function (self-diagnostic results, CAN diag-
nostic support monitor, data monitor).
