COMBINATION METERS

COMBINATION METERSPFP:24814
System DescriptionBKS001RX
UNIFIED METER CONTROL UNIT

Speedometer, odo/trip meter, tachometer and fuel gauge are controlled by the unified meter control unit,
which is built into the combination meter. Unified meter control unit receives signals from unified meter
and A/C amp.

Warning lamp and indicator lamp of combination meter are controlled by signals drawn from the unified
meter and A/C amp.

Digital meter is adopted for odo/trip meter*.
*The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.

Odo/trip meter and shift indicator segments can be checked in diagnosis mode.

Meters/gauges can be checked in diagnosis mode.
Illumination control

Unified meter control unit produces an illumination output of the
combination meter when the ignition switch is “ON”.

Light levels can be adjusted by pressing illumination control
switch of the combination meter when lighting switch is “ON”.

Illumination control switch has five light level settings.
NOTE:
When it is light outside, light level cannot be adjusted by turning
on the lighting switch.

UNIFIED METER AND A/C AMPPFP:27760
System DescriptionBKS001SK

For the unified meter and A/C amp., the signal required for con-
trolling the combination meter are integrated 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 control, refer to AT C -
24, "AIR CONDITIONER CONTROL" .

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 (with display unit) using CAN communication.

Other input signals are also sent to the ECM, TCM, BCM and display unit (with display unit) using CAN
communication.

The unified meter and A/C amp. correspond a CONSULT-II function (self-diagnostic results, CAN diag-
nostic support monitor and data monitor).
