HVAC Control Module Operation Description
S5JB0A7201007
Temperature Control
HVAC control module calculates the target temperature
control door position based on signals from the
temperature selector, inside air temperature sensor,
outside air temperature sensor and sunload sensor and
controls the temperature control actuator so that the
current position of the temperature control door matches
its target position.
Fan Speed Control
HVAC control module calculates the target blower fan
speed based on signals from the temperature selector,
inside air temperature sensor, outside air temperature
sensor and sunload sensor, compares it with the current
blower fan speed inputted from the blower motor
controller to control the current blower fan speed to the
target level.
Air Flow Outlet Control
HVAC control module calculates the target temperature
control door position based on signals from the
temperature selector, inside air temperature sensor,
outside air temperature sensor and sunload sensor.
Using thus obtained target temperature control door
position, it further calculates the target air flow control
door position and controls the air flow control actuator so
that the current air flow control door position becomes
the target position.
Air Intake Position Control
HVAC control module determines the air intake position
based on signals from the temperature selector, inside
air temperature sensor, outside air temperature sensor
and sunload sensor and controls the air intake actuator.
A/C Refrigerant Type Description
S5JB0A7201001
Whether the A/C in the vehicle being serviced uses
HFC-134a (R-134a) or CFC-12 (R-12) is indicated on
LABEL (1) on the compressor. Also, it can be checked
by the shape of the service (charge) valve (2).
