Click the button to select the engine.
Enter the new DEF injector part number, Serial number, and injection timing.
Illustration 13 g06075064
Once the new DEF injector Part number, Serial number and Injection timing values have been registered you may follow the DCU flashing procedure to obtain the new DPK flash file found in REHS9223, "Electronic Control Module (ECM) & Dosing Control Unit (DCU Flashing Procedure for the C2.4, C3.3B and C3.8 Engines".Note: Following the above procedure will ensure that any future DCU reflashing will flash the correct DEF injector information.New DEF Injector Install within Electronic Technician (ET)
The Caterpillar Electronic Technician (ET) is used to load injector trim files into the Engine Control Module (ECM).Replacing a DEF Injector
A new DEF Injection Timing Correction must be loaded into the DCU if an injector is replaced through Caterpillar Electronic Technician (ET).Replacing the DCU
Prior to replacing a DCU, It is recommended to download a Product Status Report for documentation of the DEF Injector. After replacing the DCU, ensure the DEF injector trim codes in the new DCU match the saved Product Status Report.
Establish communication between Cat ET and the engine ECM. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
