OVERVIEW
The Fuel Fired Booster Heater (FFBH) is rated at 5kW and compensates for the relatively low-coolant temperatures inherent in the engine. The unit is located behind the right front fender splash shield and heats engine coolant upstream of the heater core.
Operation of the FFBH is controlled by the Automatic Temperature Control Module (ATCM) via a Local Interconnect Network (LIN) bus connection. The operation of the FFBH is influenced by:
- Ambient air temperature.
- Engine coolant temperature.
The FFBH will operate in supplementary mode if the ambient air temperature is lower than 5ºC (41ºF) and stop if ambient temperature reaches 8ºC (46ºF), or will provide a level of heating to the cabin or engine if the ambient is below 15ºC upon a user request by either the:
- FFBH remote control,
- timed climate,
- or TS (Touch Screen).
Operation of the FFBH may also be inhibited if the fuel level drops below a predetermined level.
DESCRIPTION
INTEGRATED CONTROL PANEL WITH AUTOMATIC TEMPERATURE CONTROL MODULE

The Integrated Control Panel (ICP) is mounted in the center console and contains the Automatic Temperature Control Module (ATCM). The ATCM works in conjunction with the Engine Control Module (ECM) to control all aspects of heating, ventilation, and Air Conditioning (A/C).
For additional information, refer to: Control Components (412-01 Climate Control, Description and Operation).
