UNIFIED METER AND A/C AMP
Revision: 2005 July 2005 FX
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. correspond a CONSULT-II function (self-diagnostic results, CAN diag-
nostic support monitor, data monitor).

Solution When Communication Error Between the Unified Meter & A/C Amp. and the Combi-
nation Meter
CAN Communication System DescriptionAKS007Z1
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitAKS007YX
Refer to LAN-30, "CAN Communication Unit" in “LAN SYSTEM”.
Function Specifications
Speedometer Return to zero when discontinuing communication or receiving
irregular data.
Tachometer Reset to zero by suspending communication.
Fuel gauge
Water temperature gauge
Illumination control Combination meter illumination When suspending communication, change to nighttime mode.
Odo/trip meter Integrate in response to 8-pulse input.
A/T position indicator The display turns off by suspending communication.
Warning buzzer The warning buzzer turns off by suspending communication.
