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 change through the life of the engine. System configuration parameters must be reprogrammed if an Electronic Control Module (ECM) is replaced. System configuration parameters are not reprogrammed if the ECM software is changed. Factory passwords are required to change these parameters. The following information is a description of the system configuration parameters."Full Load Setting"
The "Full Load Setting" is a number that represents the factory adjustment to the fuel system in order to fine-tune the fuel system. If the ECM is replaced, the "full load setting" must be reprogrammed in order to prevent a 630-2 diagnostic code from becoming active."Full Torque Setting"
"Full Torque Setting" is like "Full Load Setting". If the ECM is replaced, the full torque setting must be reprogrammed in order to prevent a 630-2 diagnostic code from becoming active."Rating"
The "Rating" 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 have a different code to all other horsepower ratings and emission certifications. This rating is a code that prevents the use of an incorrect power rating and/or emission rating for a specific engine.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.
The diagnostic code 631-2 Calibration Module : Erratic, Intermittent, or Incorrect will be active.Note: The flash programming of a new rating interlock replaces the old rating interlock.The rating code is not reprogrammed when the replacement ECM is for the same engine rating.If the ECM is for a different engine rating, then the following components may require replacement: 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. 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.Factory Installed Aftertreatment #1 Identification Number
The "Factory Installed Aftertreatment #1 Identification Number" parameter ensures that the correct aftertreatment package is installed.DPF #1 Soot Loading Sensing System Configuration Code
The "DPF #1 Soot Loading Sensing System Configuration Code" is used to determine the type of diesel particulate filter soot loading sensing system. This code is a combination of two letters that identifies the orientation of the soot sensor and the geometry of the DPF. This code is used by the ECM software to identify the correct calibration table in order to match the soot
