HEUI-HI315B® Operation
The injector utilizes a two-wire, multiple
waveform electronic control strategy to
energize the solenoid and control the
injection cycle.
Injection can be tailored to provide:
Ramp Rate Shape Injection
Square Rate Shape Injection
Multiple “Split” Injections (Pilot Injection)
3 Diesel Injector Trim Codes Date
Delivery Tolerance (Trim Code)
Slight differences between
injectors have an effect on
fuel delivery.
Machining tolerances
Friction between parts
Magnetic forces
Unique Trim Codes for
each injector tailor their
performance to more closely
match the target injector.

4 Diesel Injector Trim Codes Date
Why Trim Codes are Important
The trim code affects timing and
fuel delivery throughout the ECM
map.
To get the maximum benefit from
this type of injector, you MUST
upload the trim code file to the ECM
when you install the injector. Failure
to do so may result in poor engine
performance, rough idle, poor fuel
economy, increased emissions, and
could also result in engine damage.
5 Diesel Injector Trim Codes Date
Trim Code Installation
A disc containing the unique trim code file is
supplied with each injector.
In order to enter the trim code into the ECM
either of the following is required:
Delphi Trim Code Upload Software with
NEXIQ USB Link
or
Caterpillar Electronic Technician (ET)
program with Communication Adapter 317-
7484
Failure to enter the correct trim code into
the ECM can affect engine performance and
emissions.
