UNIFIED METER AND A/C AMP
Revision: 2006 November2007 350Z
UNIFIED METER AND A/C AMPPFP:27760
System DescriptionNKS0006X
DESCRIPTION
For the unified meter and A/C amp., the signal required for con-
trolling the combination meter and triple meter are integrated in
the A/C auto amp.
Unified meter and A/C amp. corresponds a CONSULT-III func-
tion (self-diagnosis results, CAN diagnosis support monitor and
data monitor).
COMBINATION METER CONTROL FUNCTION
Unified meter and A/C amp. receives necessary information for combination meter from each unit.
Unified meter and A/C amp. converses with the combination meter transmits a signal through with com-
munication 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-7,
"FAIL-SAFE" .
