DIAGNOSIS BY HISTORY OF ERRORS
The “Self-diagnosis” results indicate whether an error occurred during the period from when the ignition switch
is turned to ON until “Self-diagnosis” is completed.
If an error occurred before the ignition switch was turned to ON and does not occur again until the “Self-diag-
nosis” is completed, the diagnosis result will be judged normal. Therefore, those errors in the past, which can-
not be found by the “Self-diagnosis”, must be found by diagnosing the “History of Errors”.
The History of Errors displays the time and place of the most recent occurrence of that error. However, take
note of the following points.

Correct time of the error occurrence may not be displayed when the GPS antenna substrate within the
NAVI control unit has malfunctioned.

Place of the error occurrence is represented by the position of the current-location mark at the time when
the error occurred. If the current-location mark has deviated from the correct position, then the place of
the error occurrence max be located correctly.

The maximum number of occurrences which can be stored is 50. For the 51st and later occurrences, the
displayed number remains 50.
When a reproducible malfunction occurred but its cause cannot be identified because several errors are
present, record the item, number and place (longitude/latitude) of error occurrence (or delete the History of
Errors), then turn the ignition switch from OFF to ON to reproduce the malfunction. Check the History of Errors
to find the items which show an increased number of occurrences, and diagnose the item.

COMBINATION METERS
Revision: 2004 November 2004 FX35/FX45
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
ECM provides a water temperature signal to unified meter and A/C amp. with CAN communication line. Uni-
fied meter and A/C amp. provides a water temperature signal to combination meter for water temperature
gauge with communication line between unified meter and A/C amp. and combination meter.
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.
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 an fuel level signal to combination meter for fuel gauge with communica-
tion line between unified meter and A/C amp. and combination meter.
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.

UNIFIED METER AND A/C AMP
Revision: 2004 November 2004 FX35/FX45
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. have a CONSULT-II function (self-diagnostic results, CAN diagnostic
support monitor, data monitor).
