AIR CONDITIONER CONTROL
AIR CONDITIONER CONTROL
Description of Air Conditioner LAN Control SystemINFOID:0000000001328167
The LAN (Local Area Network) syst em consists of unified meter and A/C amp., mode door motor, air mix door
motors and intake door motor.
A configuration of these component s is shown in the figure below.
System ConstructionINFOID:0000000001328168
A small network is constructed between the unifi ed meter and A/C amp., air mix door motors, mode door
motor and intake door motor. The unified meter and A/C amp. and motors are connected by data transmission
lines and motor power supply lines. The LAN network is built through the ground circuits of each door motor.
Addresses, motor opening angle signals, motor stop si gnals and error checking messages are all transmitted
through the data transmission lines connecting the unified meter and A/C amp. and each door motor.
The following functions are contained in LCUs built into the air mix door motors, the mode door motor and the
intake door motor.
 Address
 Motor opening angle signals
 Data transmission
 Motor stop and drive decision
 Opening angle sensor (PBR function)
 Comparison
 Decision (Unified meter and A/C amp. indicated value and motor opening angle comparison)
OPERATION
The unified meter and A/C amp. receives data from each of the sensors. The unified meter and A/C amp.
sends mode door, air mix door and intake door opening angle data to the mode door motor LCU, air mix door
motor LCU and intake door motor LCU.
The mode door motor, air mix door motors and intake door motor read their respective signals according to the
address signal. Opening angle indication signals received from the unified meter and A/C amp. and each of
the motor position sensors is compared by the LCUs in each door motor with the existing decision and open-
ing angles. Subsequently, HOT/COLD, DEF/VENT and FRE/ REC operation is selected. The new selection
data is returned to the unified meter and A/C amp.

TRANSMISSION DATA AND TRANSMISSION ORDER
Unified meter and A/C amp. data is transmitted consecut ively to each of the door motors following the form
shown in figure below.
Sta rt:
Initial compulsory signal is sent to each of the door motors.
Address:
Data sent from the unified meter and A/C amp. are selected according to data-based decisions made by the
air mix door motor, mode door motor and intake door motor.
If the addresses are identical, the opening angle data and error check signals are received by the door motor
LCUs. The LCUs then make the appropriate error decis ion. If the opening angle data have no error, door con-
trol begins.
If an error exists, the received data are rejected and corrected data received. Finally, door control is based
upon the corrected opening angle data.
Opening Angle:
Data that shows the indicated door opening angle of each door motor.
Error Check:
In this procedure, transmitted and received data is check ed for errors. Error data are then compiled. The error
check prevents corrupted data from being used by the ai r mix door motor, the mode door motor and the intake
door motor. Error data can be related to the following symptoms.
 Malfunction of electrical frequency
 Poor electrical connections
 Signal leakage from transmission lines
 Signal level fluctuation
Stop Signal:
At the end of each transmission, a stop operation, in-oper ation, or internal malfunction message is delivered to
the unified meter and A/C amp. This comple tes one data transmission and control cycle.

BCM (BODY CONTROL MODULE)
When BCM is in sleep status, transistors of OUTPUT 1 and 5 stop the output, and BCM enters low power
mode. Mean while OUTPUT 2, 3, and 4 send out ON signal every 60 ms, and accept input from lighting
switch system.
CAN COMMUNICATION CONTROL
CAN communication allows a high rate of information transmission through the two communication lines (CAN
L line, CAN H line) connecting the various control units in the system. Each control unit transmits/receives
data but selectively reads required data only. For details of signals that are transmitted/received by BCM via
CAN communication, refer to LAN-43, "
CAN System Specification Chart".
BCM STATUS CONTROL
BCM changes its status depending on the operation stat us in order to save power consumption.
1. CAN communication status  With ignition switch ON, CAN communicates with other control units normally.
 Control by BCM is being operated properly.
 When ignition switch is OFF, switching to sleep mode is possible.
 Even when ignition switch is OFF, if CAN communication with IPDM E/R and combination meter isactive, CAN communication status is active.
2. Sleep transient status  This status shuts down CAN communication when ignition switch is turned OFF.
 It transmits sleep request signal to IPDM E/R and combination meter.
 2 seconds after CAN communication of all control units stops, sleep transient status is switched to CAN
communication inactive status.
3. CAN communication inactive status  With ignition switch OFF, CAN communication is not active.
 With ignition switch OFF, control performed only by BCM is active.
 3 seconds after CAN communication of all control units stops, CAN communication inactive status is
switched to sleep status.
4. Sleep status  BCM is activated with low power mode.
 CAN communication is not active.
 When CAN communication operation is detected, it switches to CAN communication status.
 When a state of the following switches changes , it switches to CAN communication state.
- Key switch
- Hazard switch
