System Description

NKS001SN

●

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

●

The unified meter and A/C amp. corresponds to a CONSULT-II 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 malfunction. Refer to
