SYSTEM DESCRIPTION
Auto amplifier controls compressor operation by ambient temperature and signal from ECM.
Low Temperature Protection Control
Auto amplifier will turn the compressor ON or OFF as determined by
a signal detected by ambient sensor.
When ambient temperatures are greater than
−
2
°
C (28
°
F), the com-
pressor turns ON. The compressor turns OFF when ambient temper-
atures are less than
−
5
°
C (23
°
F).
DIAGNOSTIC PROCEDURE FOR MAGNET CLUTCH
SYMPTOM: Magnet clutch does not engage when A/C switch is ON.
