IPDM E/R

A/C relay is integrated in IPDM E/R. IPDM E/R operates A/C relay when re-
ceiving A/C compressor request signal from ECM via CAN communication 
line.
IPDM E/R controls ECV compressor when receiving ECV control signal from 
A/C amp. via CAN communication line.
Refer to 

PCS-5, "Component Parts Location"

 for detailed installation loca-

tion.

ECM

ECM, when receiving A/C ON signal and blower fan ON signal from A/C 
amp., transmits A/C compressor request signal to IPDM E/R via CAN com-
munication according to status of the engine and refrigerant pressure.
ECM receives cooling fan request signal from A/C amp.
ECM transmits engine coolant temperature signal and refrigerant pressure 
sensor signal to A/C amp. via CAN communication line.
Refer to 

EC-28, "ENGINE CONTROL SYSTEM : Component Parts Loca-

tion"

 (MR20DD engine models) or
