CONTROL BY A/C amp.
Low Temperature Protection Control
When intake sensor detects that evaporator fin temperature is
[−5.0°C (23.0°F)] or less, A/C amp. requests ECM to turn the A/C compressor OFF, and stops the A/C compressor.
When the air temperature returns to
[−2.0°C (28.4°F)] or more, the A/C compressor is activated.
A/C Compressor Oil Circulation Control
When the engine starts, A/C amp. activates the A/C compressor for a few seconds and circulates the A/C compressor oil once.
