Overview

OVERVIEW

NOTE: There is no auxiliary coolant pump fitted if there is no FFBH fitted (from VIN 631090).

The Fuel Fired Booster Heater (FFBH) is rated at 5 kW and compensates for the relatively low coolant temperatures inherent in the diesel engine. The unit is located behind the RH (right-hand) front fender splash shield and heats engine coolant downstream of the heater core.

Operation of the FFBH is controlled by the ATC (automatic temperature control) module via the medium speed CAN (controller area network) bus. The operation of the FFBH is influenced by:

• Ambient air temperature
• Engine coolant temperature.

The FFBH will operate if the ambient air temperature is lower than 5
