AIR CONDITIONING – AIR CONDITIONING SYSTEM (for Automatic Air Conditioning Sys-
tem)AC–13
AC
SYSTEM DESCRIPTION
1. GENERAL
(a) The air conditioning system has the following
features:
• In accordance with the temperature set using the
temperature control switch, the air conditioning
amplifier determines the outlet temperature
based on the input signals from various sensors.
In addition, corrections are made in accordance
with the signals from the water temperature
sensor to control the outlet air temperature.
• Controls the blower motor in accordance with the
airflow volume determined by the air conditioning
amplifier based on the input signals from various
sensors.
• Automatically changes the outlets in accordance
with the outlet mode ratio that is determined by
the air conditioning amplifier based on the input
signals from various sensors.
• Based on the signals from the ambient
temperature sensor, this system calculates the
outside temperature and indicates it in the multi-
information display in the combination meter
assembly.
• The left/right independent temperature control
and neural network control make air conditioner
control available to suit the persons in the driver
seat and in the passenger seat.
• Turns the rear defogger and outside rear mirror
heaters on for 15 minutes when the rear
defogger switch is pressed. Turns them off if the
switch is pressed while they are operating.
• Checks the sensors in accordance with the
operation of the air conditioner switches.
• The air conditioning amplifier has the function of
controlling the indicator lighting.
