UNIFIED METER AND A/C AMP

System Description
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

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 "AIR CONDITIONER CONTROL" in Automatic Air Condition.

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.
