Regulating the air conditioning (A/C) compressor
The air conditioning (A/C) compressor is controlled by the engine control module (ECM) (4/46) on request from the climate control module (CCM)
(3/112) via the controller area network (CAN). When the engine control module (ECM) receives a signal from the climate control module (CCM) to
activate the air conditioning (A/C) compressor, the engine control module (ECM) grounds the circuit for the relay coil for the A/C compressor. See also:
Design See: Description and Operation/Engine Control Module (ECM)/Design
The relay (2/22) closes the circuit between the integrated relay/fuse box in the engine compartment and the clutch for the A/C compressor (8/3).
In addition to the information from the climate control module (CCM), the engine control module (ECM) checks the engagement and disengagement of
the A/C compressor based on:
-
the signal from the air conditioning (A/C) pressure sensor (high pressure side) (7/8)
-
the signal from the air conditioning (A/C) pressure sensor (low pressure side) (8/119)
-
the throttle position (TP) sensor (6/120)
-
the engine coolant temperature (ECT) sensor (7/16).
