When a fuel injector group is serviced, the new fuel injector group's electronic injector code must be programmed into the engine's personality module software by using the calibration menu on the Electronic Service Tool. If the new fuel injector group's electronic code is not entered, the previous fuel injector group's characteristics are assumed.If it is not possible to immediately reprogram the electronic injector code of the injector into the personality module software, the engine will not be severely harmed. The new electronic injector code should be reprogrammed as quickly as possible in order to optimize engine performance.
Note: Injector code (10) will be located on either the side, as illustrated, or on the top of the injector. Should the code be located in both places, use the code that is located on the side.
If the injectors have been replaced, record injector code (10) for programming.
