Electric Booster Heater

NOTE:
A = Hardwired;









General
Operation of the electric booster heater is controlled by the ATC (automatic temperature control), which communicates with the micro-controller in the booster heater using the LIN (local interconnect network) bus. The temperature requested by the ATC (automatic temperature control) module is based on:
- The ambient air temperature
- The engine coolant temperature
- The temperatures selected on the integrated control panel.
The blower must be running for the electric booster heater to operate.
If the electrical load management is in force, the electric booster heater performance is reduced. For additional information, refer to:For additional information, refer to Electronic Engine Controls
