Compressor Oil Circulation Control
When the engine starts while the engine coolant temperature is 56
°
C (133
°
F) or less, ECM activates the com-
pressor for approximately 6 seconds and circulates the compressor oil once.
Air Conditioning Cut Control
When the engine condition is high load, ECM makes the A/C relay to OFF, and stops the compressor. Refer to
following.

PTC HEATER CONTROL SYSTEM : System Diagram
INFOID:0000000006660955
PTC HEATER CONTROL SYSTEM : System Description
INFOID:0000000006660956
• PTC heater control unit performs PTC relay ON/OFF control based on engine speed, engine coolant tem-
perature, electrical power cut freeze signal (permission signal, retention signal, stop signal), fan speed,
ambient temperature, battery voltage, and electrical load signal (high beam request signal, low beam
request signal, rear window defogger ON signal, and others).
• When PTC relay turns ON, power supply is supplied to PTC heater. Heating element is heated and air flow
temperature is increased. Heating is available for a period of time until engine coolant temperature is
increased when engine starts cold in cold climate.
• Idle up request signal is transmitted from PTC heater control unit to ECM while PTC heater operates. Idle
speed is increased, warming-up is facilitated, and battery electric power is obtained.
• Electric power supplied to PTC heating element is subject to PTC relay control conditions.
NOTE:
PTC heater operation depends on ambient temperature and battery voltage. PTC heater is ON when ambient
temperature is 8
°
C or less. PTC heater is OFF when ambient temperature is 12
°
C or more. PTC heater is ON
when battery voltage is 11.5 V or more. PTC heater is OFF when battery voltage is 11 V or less.
