Module Reprogramming
WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. 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. Module reprogramming is automatically carried out during PMI when a later strategy/calibration is available.
Reprogramming a module with the same level of software will not improve module operation or repair a hardware failure.
NOTE:
Module reprogramming should be limited to circumstances where a published Technical Service Bulletin (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 reprogramming.
