System Description

NKS003UG

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

COMBINATION METER CONTROL FUNCTION

●

Unified meter and A/C amp. inputs necessary information for combination meter from each unit with CAN
communication and so on.

●

Unified meter and A/C amp. outputs signals with communication line (TX, RX) between unified meter and
A/C amp. and combination meter.

●

Unified meter and A/C amp. corresponds a CONSULT-II function (self-diagnostic results, CAN diagnostic
support monitor and data monitor).

Input/output Signals

Between unified meter and A/C amp. and combination meter.

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-

29, "AIR CONDITIONER CONTROL"

  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 transmit to the AV control unit (without NAVI) or NAVI control unit (with NAVI)
with CAN communication.

Signal Buffer Function

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