Module Reprogramming
WARNING: This page is about a different car, the 2011 Ford RV Cutaway, 2011 Ford Econoline, 2011 Ford E450 Super Duty, and 2011 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
Module reprogramming (also referred to as "flashing") is a scan tool process which updates the strategy/calibration in a module. Reprogramming a module with the same level of software does not improve module operation or repair a hardware failure. Module reprogramming is automatically carried out during PMI when a later strategy/calibration is available.
NOTE:
Module reprogramming should be limited to circumstances where a published TSB procedure recommends doing so.
NOTE:
A module cannot communicate with other modules on the communication network while being reprogrammed. Clear any network communication DTCs which may have been set in other modules during the reprogramming process.
