  5. Auxiliary Heater Heating Element -Z35- (with Auxiliary Air Heater Control Module -J604-)
    • Only on diesel vehicles, refer to Vehicle Diagnosis, Testing and Information System VAS 5051 in "Guided Fault Finding" function.
    • The electric auxiliary air heater is available in different versions. On vehicles equipped with a diesel engine built through November 2006 (running change) the control of the auxiliary air heater heating element via the auxiliary air heater control module, refer to Vehicle Diagnosis, Testing and Information System VAS 5051 in "Guided Fault Finding" function. On diesel vehicles built from November 2006 (running change) have a 3-stage auxiliary air heater heating element which is controlled by a relay from the Engine Control Module (ECM). Refer to Vehicle Diagnosis, Testing and Information System VAS 5051 in "Guided Fault Finding" function and refer to the appropriate SYSTEM WIRING DIAGRAMS information.
    • At this time, an auxiliary heater heating element is also installed in vehicles with Diesel engine and parking heater as optional equipment. At a later point in time (not yet finalized), the auxiliary heater heating element will be discontinued, then the parking heater undertakes the function of the auxiliary heater.
    • Check the auxiliary air heater control module, perform Guided Fault Finding using Vehicle Diagnosis, Testing and Information System VAS 5051.
