Ambient sensor
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-
(MR20DD engine models) or
EC-812, "Component Parts Location"
(R9M engine models) for detailed installation location.
Combination meter
Combination meter transmits ambient temperature signal and vehicle speed
signal to A/C amp. via CAN communication line.
