Temperature Setting Trimmer

INFOID:0000000006626875

DESCRIPTION

If the temperature felt by the customer is different from the air flow temperature controlled by the temperature
setting, the A/C auto amp. control temperature can be adjusted to compensate for the temperature setting.

HOW TO SET

With CONSULT-III

Perform “TEMP SET CORRECT” of HVAC work support item.

celled.

Inlet Port Memory Function (REC)

INFOID:0000000006626878

DESCRIPTION

• If the ignition switch is turned to the OFF position while the intake switch is set to ON (recirculation), “Per-

form the memory” or “Do not perform the memory” of intake switch ON (recirculation) condition can be
selected.

• If “Perform the memory” was set, the intake switch will be ON (recirculation) when turning the ignition switch

to the ON position again.

• If “Do not perform the memory” was set, the air inlets will be controlled automatically when turning the igni-

tion switch to the ON position again.

HOW TO SET

With CONSULT-III

Perform the “REC MEMORY SET” of HVAC work support item.

NOTE:
When the battery cable is disconnected from the negative terminal or when the battery voltage becomes 10 V
or less, the setting of the REC memory function may be cancelled.

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000006627100

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-board mul-
tiplex communication line with high data communication speed and excellent error detection ability. A modern
vehicle is equipped with many ECMs, and each control unit shares information and links with other control
units during operation (not independent). In CAN communication, 2 control units are connected with 2 commu-
nication lines (CAN-L line and CAN-H line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
Refer to

LAN-31, "CAN COMMUNICATION SYSTEM : CAN Communication Signal Chart"

for details of the

communication signal.
