Injector confirmation code may not need to be programmed into engine Electronic Control Module
(ECM) when injectors are exchanged for testing purposes only.
When an electronic fuel injector is replaced, the new 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 electronic injector code is not entered, the characteristics of the previous electronic fuel
injector are assumed.
If it is not possible to immediately reprogram the electronic injector code into the personality module
software, the engine will not be severely harmed. The new electronic injector code should be repro-
grammed as quickly as possible in order to optimize engine performance.
Program E-Trim value of each new injector into engine control module. E-Trim value is a 12-digit alphanumeric code
that is supplied with data sheet that comes with new injectors. Injector Confirmation Code is a 4-digit numeric code.
Both codes are located on top of electronic fuel injector (2). Use this menu to program E-Trim value:
