PTC (Positive Temperature Coefficient)
This supplementary heater is an electrical air heating type and
installed on the heater outlet port. This device improves the heating
effect by increasing the temperature of flowing air into the passen-
ger room.
This device is operational/non-operational when the engine control
unit supplies/cuts off the voltage to PTC according to the coolant
temperature and the ambient temperature.
Operational Condition
This device is activated when the temperature switch is at any
position other than "OFF" position and the coolant temperature and
the ambient temperature is within a specified range.
Non-operational Condition
- The temperature switch is at "OFF" position
- Defective ambient temperature sensor
- During engine cranking
- Too low battery voltage
- During pre-glowing process ( indicator ON)
