System Configuration Parameters affect the emissions of the engine or the power of the engine. System configuration parameters are programmed at the factory. Normally, system configuration parameters would never need to be changed through the life of the engine. System configuration parameters must be reprogrammed if an ECM is replaced. Unless the engine rating has changed, system configuration parameters do not need to be reprogrammed when the flash file is changed. The correct values for these parameters are stamped on the engine information ratings plate. The engine information ratings plate is located on the valve cover or on the air intake manifold. Factory passwords are required to change these parameters. The following information is a description of the system configuration parameters."Full Load Setting"
"Full Load Setting" is a number that represents the adjustment to the fuel system that was made at the factory in order to fine tune the fuel system. The correct value for this parameter is stamped on the engine information ratings plate. If the ECM is replaced, the "full load setting" must be reprogrammed in order to prevent a 253-02 diagnostic code from becoming active."Full Torque Setting"
"Full Torque Setting" is similar to "Full Load Setting". If the ECM is replaced, the full torque setting must be reprogrammed in order to prevent a 253-02 diagnostic code from becoming active.Rating Interlock
The Rating Interlock is a code that prevents the use of an incorrect power rating and/or emission rating for a specific engine. Each horsepower rating and each emission certification has a different code to all other horsepower ratings and emission certifications.When an ECM is replaced, this rating interlock code must match the code that is stored in the ECM. If the rating interlock code does not match the code that is stored in the ECM, both of the following situations will exist:
The engine will not run.
Diagnostic code 253-02 will be active.Note: The flash programming of a new rating interlock replaces the old rating interlock.This code does not need to be programmed when the replacement ECM is from the same engine rating.If the ECM is from a different engine rating, the following components may need to be changed: pistons, fuel injectors and other components. The engine information ratings plate must also be changed in order to reflect the new rating.Some systems such as the cooling system or the transmission may also require changes when the engine is rerated. Please contact the local OEM dealer for further information."Engine Serial Number"
When a new ECM is delivered, the engine serial number in the ECM is not programmed. The "Engine Serial Number" should be programmed to match the engine serial number that is stamped on the engine information plate."ECM Software Release Date"
This parameter is defined by the rating interlock and this parameter is not programmable. The "ECM Software Release Date" is used to provide the version of the software. The Customer parameters and the software change levels can be monitored by this date. The date is provided in the month and the year
