A/C AUTO AMP.
A/C AUTO AMP.: Description
COMPONENT DESCRIPTION
A/C Auto Amp. (Air Conditioner Automatic Amplifier)
The A/C auto amp. (1) has a built-in microcomputer that processes information sent from various sensors needed for air conditioner operation. The air mix door motor(s), the mode door motor, the intake door motor, the blower motor and the A/C compressor are then controlled.
When the various switches and temperature control switches are operated, data is input to the A/C auto amp. from the AV switch assembly using CAN communication.
The A/C auto amp. is operated with control mechanisms. Signals from various switches and Potentio Temperature Control (PTC) are directly entered into the A/C auto amp.

Description
In-vehicle Sensor
The in-vehicle sensor (1) is located on instrument lower cover
(LH).
It converts variations in compartment air temperature drawn from
the aspirator into a resistance value. It is then input into the A/C
auto amp.
