COMBINATION METERS
Revision: 2004 November 2004 FX35/FX45
COMBINATION METERSPFP:24814
System DescriptionAKS005MH
UNIFIED METER CONTROL UNIT

Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the
unified meter control unit, which is built into the combination meter. Unified meter control unit receives sig-
nals 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, A/T indicator and ICC system display segments can be checked in diagnosis mode.

Meters/gauges can be checked in diagnosis mode.
Illumination Control
The unified meter control unit outputs the odo/trip meter and A/T
indicator lighting when the ignition switch is turned on. When the
lighting switch is turned on, light on for the combination meter dial,
illumination control switch and external lighting are output. In addi-
tion, when the lighting switch is turned on, the illumination control
switch on the left side of the combination meter can be used to
adjust the brightness of each light. The brightness can be adjusted
to sixteen different levels: From 0 (no lights) to 15 (maximum).
Pressing the illumination control switch will brighten or darken the
lights. When the key switch is in the START position, the combina-
tion meter dial lighting and illumination control switch lighting are
turned off.
UNIFIED METER AND A/C AMP.
Refer to DI-28, "System Description" in “UNIFIED METER AND A/C AMP”.
