No.	Component	Description
1.	IPDM E/R	A/C relay is integrated into IPDM E/R. IPDM E/R operates A/C relay when A/C compressor request signal is received from ECM via CAN communication line. Refer to Component Parts Location for detailed installation location.
2.	ECM	The ECM sends an A/C compressor ON request to the IPDM E/R based on the status of engine operation and load as well as refrigerant pressure information. If all the conditions are met for A/C operation, the ECM transmits the A/C compressor ON request to the IPDM E/R. The ECM shares the refrigerant pressure sensor signal, engine RPM, and engine coolant temperature with the A/C auto amp. via CAN communication line. Refer to Component Parts Location for detailed installation location.
3.	A/C compressor	Refer to A/C Compressor .
4.	Sunload sensor	Refer to Sunload Sensor .
5.	BCM	BCM transmits blower motor ON signal to the front blower motor relay. Refer to Component Parts Location for detailed installation location.
6.	In-vehicle sensor	Refer to In-vehicle Sensor .
7.	Fuse block (J/B) (Front blower motor relay)	Located in the passenger compartment behind the instrument panel RH, the fuse block (J/B) contains the front blower motor relay and several fuses required for the air conditioner control system. The front blower motor relay controls the flow of current to fuse 17 and 27 in the fuse block (J/B). The relay is connected directly to ground and is controlled by the BCM.
