IPDM E/R

A/C relay is integrated in IPDM E/R. IPDM E/R operates A/C relay when 
receiving A/C compressor request signal from ECM via CAN communica-
tion 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 BCM, 
transmits A/C compressor request signal to IPDM E/R via CAN communi-
cation according to status of the engine and refrigerant pressure.
ECM transmits engine coolant temperature signal to combination meter via 
CAN communication line.
