UNIFIED METER AND A/C AMPPFP:27760
System DescriptionAKS005N8
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.
Unified meter and A/C amp. controls each operation for A/C auto amp. For information regarding A/C con-
trol, refer to AT C - 3 0 , "
AIR CONDITIONER CONTROL" in ATC section.
Unified meter and A/C amp. inputs necessary information for combination meter from each unit by CAN
communication and so on.
And unified meter and A/C amp. outputs these signals using communication line (TX, RX) between unified
meter and A/C amp. and combination meter.
The signals required for the distance to empty (DTE) display are centralized in the unified meter and A/C
amp., converted into data, and sent to the display unit (without NAVI) display control unit (with NAVI) using
CAN communication.
Other input signals are also sent to the ECM, TCM, AWD control unit, BCM, display unit (without NAVI)
and display control unit (with NAVI) using CAN communication.
The unified meter and A/C amp. have a CONSULT-II function (self-diagnostic results, CAN diagnostic
support monitor, data monitor).
