Electric Booster Heater - System Operation And Component Description (G970489): General

Operation of the electric booster heater is controlled by the ATC module, which communicates with the micro-controller in the booster heater using the LIN bus. The temperature requested by the ATC 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 electrical load management is in force, electric booster heater performance is reduced. For additional information, refer to:
