(12) 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.
Position the unit injector (3) in the cylinder head assembly. Place the hold down clamp (10) at the base of the unit injector. Push down on the return spring of the unit injector in order to seat the unit injector.
Install spacer assembly (9) and bolt (8) that holds the unit injector in place.
Pull the unit injector completely into the bore. Tighten the bolt to a torque of 30 N m (22 lb ft).
Install cap assembly (5). Tighten nuts (6) to a torque of 2.5 0.25 N m (22 2 lb in).
Install bridge assemblies (7) onto the valve stems.
