UNIFIED METER AND A/C AMP
UNIFIED METER AND A/C AMP
System DescriptionINFOID: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 CONS ULT-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 AT C -
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 disp lay 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.
