PTC Heater
COMPONENT FUNCTION WITHIN SYSTEM
Heat element is heated and air flow temperature is increased by power supply from BCM controlled PTC heater relay.
INDIVIDUAL COMPONENT FUNCTION
Heat element is heated and air flow temperature is increased.
COMPONENT OPERATION
The PTC heater utilizes a PTC element is adopted.
| note | The PTC  thermistor generates heat in response to current flow. The temperature (and resistance) of the thermistor element varies with current flow. Excessive current flow will cause the element's temperature to rise. When the temperature reaches a specified level, the electrical resistance will rise sharply to control the circuit current. |
COMPONENT PARTS LOCATION
The PTC heater is installed to the heater & cooling unit assembly.
