UNIFIED METER AND A/C AMP
Revision: 2006 December 2006 FX35/FX45
UNIFIED METER AND A/C AMPPFP:27760
System DescriptionNKS00300
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 malfunctioning. Refer to DI-8,
"FAIL-SAFE" . Unit Input Output
