Note
Depending on the required cool‐
♦
ing output, the regulating valve
receives a PWM signal (500 Hz)
(modulated by signal interval)
from the air conditioning system
control unit - J301- and regulates
the displacement of the AC com‐
pressor via the position of the
articulated disc.
Not fitted in the vehicles assem‐
♦
bled in India (AC compressors
with air conditioning system
magnetic coupling - N25- ).
❑ Elements of the AC compressor, do not replace individually
