Should a customer express concern that the fuel fired parking heater (FFPH) does not heat up the passenger
cabin sufficiently, the probable cause is that the blower is switched on much too late and not distributing the
heat into the passenger cabin. The FFPH itself is working faultless.
To rectify this concern, a revised FFPH software should be installed.
Use IDS 64.08 DVD or a later version. Before commencing module configuration or programming, connect
the vehicle battery to a suitable external power supply in order to maintain a constant battery voltage
throughout the procedure. For detailed information refer to TSB 62/2007. For markets where FordEtis IDS is
used, connect FordEtis IDS and select the appropriate symptoms from the concern descriptions above.
Follow the FordEtis IDS instructions to rectify this concern and send any related diagnostic feedback session
files. Failure to follow these instructions will affect any associated warranty claim submission.
For markets where FordEtis IDS is not available, use the IDS standard portable diagnostic unit. Rectify this
concern by following the attached service repair instruction.
Labor Times published in this TSB are available 18th November onwards. Please refresh your Labor Master

Ist auf jeden Fall einen Versuch wert, beim Feindlichen mal zu fragen, oder?
