UNIFIED METER AND A/C AMP

UNIFIED METER AND A/C AMP

System Description

INFOID:0000000001328456

• For the unified meter and A/C amp., the signal required for controlling the combination meter are integrated

in the A/C auto amp.

• The unified meter and A/C amp. corresponds to a CONSULT-III function (self-diagnosis results, CAN diag-

nosis support monitor, data monitor).

COMBINATION METER CONTROL FUNCTION

• Unified meter and A/C amp. receives necessary information for combination meter from each unit by CAN

communication.

• Unified meter and A/C amp. transmits a signals with communication line (TX, RX) between unified meter and

A/C amp. and combination meter.

Input/output signals between unified meter and A/C amp. and combination meter.

NOTE:

Combination meter performs fail-safe operation when unified meter and A/C amp. communication is malfunctioning. Refer to 

DI-5, "Sys-

tem Description"

.

A/C AUTO AMP. FUNCTION

Unified meter and A/C amp. controls each operation for A/C auto amp. Regarding A/C control, refer to 

ATC-

24, "Description of Air Conditioner LAN Control System"

 in ATC section.

OTHER FUNCTIONS

Drive Computer Function

The signals required for the distance to empty (DTE) display are centralized in the unified meter and A/C
amp., converted into data, and transmitted to the display unit (without NAVI) and display control unit (with
NAVI) using CAN communication.

Signal Buffer Function

Unified meter and A/C amp. transmits each signal to other units with CAN communication.
