HARNESS AS-ENGINE 4658268 - Caterpillar

"Full Load Setting"
The "Full Load Setting" represents the factory adjustment that was made 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 268-2 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 268-2 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. Every horsepower rating and emission certification has a unique code. This code 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 253-2 Personality Module : Erratic, Intermittent, or Incorrect will be active.Note: The flash programming of a new rating interlock replaces the old rating interlock.Reprogramming of the rating is not required 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
Other engine componentsNote: The engine information ratings plate must also be changed in order to reflect the new rating.Certain other systems such as the cooling system or the transmission may also require changes when the engine is rerated. Contact a Caterpillar 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 sensor system to the DPF. The calibration table optimizes the soot readings."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 (JAN10). Jan is the month (January). 10 is the year (2010).
