COMBINATION METERS
Revision: 2004 November 2004 FX35/FX45
2. CHECK WARNING LAMP ILLUMINATION
Turn ignition switch ON. (Engine stopped)
Do warning lamps (such as malfunction indicator lamp and oil pressure warning lamp) illuminate?
YES >> GO TO 3.
NO >> Check ignition power supply system of combination meter. Refer to DI-15, "
Power Supply and
Ground Circuit Inspection" .
3. CHECK SELF-DIAGNOSIS OPERATION OF COMBINATION METER
Perform combination meter self-diagnosis. Refer to DI-12, "
SELF-DIAGNOSIS FUNCTION" .
Does self-diagnosis function operate?
YES >> GO TO 4.
NO >> Check battery power supply of combination meter and ground system. Refer to DI-15, "
Power
Supply and Ground Circuit Inspection" .
4. CHECK ODO/TRIP METER OPERATION
Check odo/trip meter segment, A/T indicator or ICC system display segment.
Do all segments illuminate?
YES >> GO TO 5.
NO >> Replace combination meter.
5. CHECK LOW-FUEL WARNING LAMP ILLUMINATION CONFIRMATION
During low-fuel warning lamp check, confirm illumination of low-fuel warning lamp.
OK or NG
OK >> GO TO 6.
NG >> Replace combination meter.
6. CHECK COMBINATION METER CIRCUIT
Check indication of each meter/gauge in self-diagnosis mode.
OK or NG
OK >> Go to DI-16, "Symptom Chart 1" .
NG >> Replace combination meter.

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).

Solution When Communication Error Between the Unified Meter & A/C Amp. and the Combi-
nation Meter
CAN Communication System DescriptionAKS007Z1
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitAKS007YX
Refer to LAN-6, "CAN Communication Unit" in “LAN SYSTEM”.
