AIR CONDITIONING (AUTOMATIC A/C)
5. AIR CONDITIONING OPERATION
The A/C control assembly receives various signals, I.E., the engine RPM from the engine control module, out side air
temperature signal from the A/C ambient temp. sensor, coolant temperature from the engine control module and the lock
signal from the A/C compressor, etc.
When the engine is started and the A/C SW (A/C control assembly) is on, a signal is input to the A/C control assembly.
As a result, the ground circuit in A/C control assembly is closed and current flows from HEATER fuse to TERMINAL 1 of
the MG CLT relay to TERMINAL 2 to TERMINAL 3 of the diode (A/C) to TERMINAL 2 to TERMINAL MGCR of the A/C
control assembly to TERMINAL GND to GROUND, turning the MG CLT relay on, so that the magnetic clutch is on and the
A/C compressor operates.
At the same time, the engine control module. Detects the magnetic clutch is on and the A/C compressor operates.
If the A/C control assembly detects the following conditions, it stops the air conditioning:
*Evaporator outlet air is too low.
*There is a marked difference between the compressor speed and the engine speed.
*The refrigerant pressure is abnormally high or abnormally low.
*The engine speed is too low.
*Rapid acceleration occurs.
