COMBINATION METER
CHASSIS ELECTRICAL54A-10
COMBINATION METER
M2540005000894
The combination meter features large, clearly visible
analogue indicators. The meter has the speedometer
in the middle, the coolant temperature gauge at
upper right, the fuel gauge at lower right, and the
tachometer at left so that drivers can easily distin
-
guish the information from the meters. The combina-
tion meter offers the following advantages.
•The combination meter is used for air conditioner
and meter drive control to integrate ECU.
•CAN communication is used for more reliable
transmission of all gauge data and indicator lamp
input signals, such as vehicle speed, engine
RPM, and coolant temperature. For further
details on CAN, refer to GROUP 54C, CAN
P.54C-2. The signals that the combination meter
uses are described in the CAN communications
input signals table
.
•Several diagnosis functions such as the diagno-
sis code memory and actuator tests are prepared
in order to improve serviceability.
•For a brighter display at night and for a longer
useful life, all indicator lamps, warning lamps, and
illumination bulbs use LEDs.
•The indicators for the speedometer, fuel gauge,
and other gauges are driven by a stepping motor.
For further details, consult the stepping motor
section
.
•The electronic speedometer operates by receiv-
ing vehicle speed signals sent by the
engine-ECU or engine-CVT-ECU
via the CAN.
•A large and clear LCD type odo-tripmeter is pro-
vided. The odometer continuously displays val-
ues while the tripmeter adopts a twin-trip (trip A,
trip B) function which is switched by a reset but
-
ton. In addition, clock function is incorporated.
•A fog lamp indicator lamp is provided to let the
driver know that the fog lamp is on.
•A seat belt warning lamp is installed to encourage
the driver to fasten the seat belt.
•The high-contrast meter is adopted. When the
ignition is turned ON, such as the needles and
face display are illuminated with fade-in lighting
by the LED light source.
•To further accentuate the high-contrast lighting,
the light of the high-contrast meter fades in and
fades out when the light is turned on and off
respectively.
•With the auto illumination function incorporated in
the high-contrast meter, a two-stage switching of
daytime (non-dimming) and nighttime (dimming)
is achieved. Also, the brightness can be adjusted
using the illumination control knob.
•A tail lamp indicator lamp is installed which
informs the lighting status of the tail lamps to the
driver.

TECHNICAL FEATURES
GENERAL00-29
IMPROVED SERVICEABILITY
•Employment of an automatic hydraulic timing belt
tensioner offers timing belt reliability, reduced
operating noise, and better serviceability. <4G1>
•Wiring harness section of the crank angle sensor
has been moulded integrally with the timing belt
cover, improving serviceability and reliability.
<4G1>
•Due to the adoption of the timing chain and the
timing chain tensioner, maintenance-free and reli
-
ability have been improved. <4A9>
•Since adoption of unvolatile memory (EEPROM*)
helps the learned value not to be initialised when
the battery terminal or connector of the control
unit is disconnected, maintainability can be
improved.
NOTE: *EEPROM: Electrical Erasable Programma-
ble ROM (information to be memorised can be
electronically written into and erased from ROM)
•Since the adoption of electric power steering
makes hydraulic pipes and oil pumps unneces
-
sary, maintainability can be improved.
•Employment of operative A/C piping layout and
refrigerant leak detection system enhances serv
-
iceability.
