An injector trim file must be loaded into the ECM if an injector is replaced.

Replacing the ECM

The “Copy Configuration” utility on Cat ET copies the injector trim files between two engine control modules. If the “Copy Configuration” fails, load all of the injector trim files manually into the new ECM.

“Injector Trim” is displayed below a 268-2 or 630-2 Programmed Parameter Fault : Erratic, Intermittent, or Incorrect. The diagnostic code is displayed on Cat ET.

Exchanging Injectors

Exchanging injectors can help determine if a combustion problem is in the injector or in the cylinder. If two injectors that are currently installed in the engine are exchanged between cylinders, the injector trim files can also be exchanged. Press the “Exchange” button at the bottom of the “Injector Trim Calibration” screen on Cat ET. Select the two injectors that have been exchanged and press the “OK” button. The tattletale for the injectors that were exchanged will increase by one.
