(11) Electronic injector code
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.
If a new unit injector or a different unit injector is installed, program the electronic injector code.End By:
Install rocker arm assemblies and pushrods.
Adjust the unit injectors. Refer to the Testing and Adjusting, "Fuel System" topic for the proper procedure.
