Definition of Terms
The following are definitions of configuration terms
Module Reprogramming
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 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.
Programmable Parameters
Programmable parameters are customer preference items that may be modified by the dealer via scan tool or in some cases modified by the customer following a procedure listed in the vehicle Owner's Literature. While many configuration options may exist for a module, only a few of these options are programmable parameters.
