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.
When a new ECM is delivered, the ECM serial number is pre-programmed.
When a new ECM is delivered, the ECM part number is pre-programmed.
When a new ECM is delivered, the following software group information is pre-programmed:
- Software Group Part Number
- Software Group Release Date
- Software Group Description
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.
The rating includes the following parameters:
- Rated speed
- Rated torque
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, the engine will not run.
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.
