Entering New Fuel Injector Trim Files Within Cat^® Electronic Technician Cat(ET)

The Caterpillar Electronic Technician (ET) is used to load injector trim files into the Engine Control Module (ECM).

Replacing an Injector

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

Replacing the Engine ECM

Prior to replacing an ECM, it is recommended to download a Product Status Report for documentation of the injector trim codes. After replacing the Engine ECM, ensure the injector trim codes in the new Engine ECM match the saved Product Status Report.

1. Record the injector trim code for each cylinder.

   C2.4 Fuel Injector

   Note: The injector serial number and the injector confirmation code are located on the injector. Record the injector serial number and the injector confirmation code (5) for each injector.

2. Establish communication between Cat ET and the engine ECM. Refer to Troubleshooting, "Electronic Service Tools", if necessary.

3. Select the following menu options on Cat ET:

   • Service

   • Calibrations

   • Injector Code Calibration

4. Select the appropriate cylinder.

5. Click the "Change" button.

6. Enter the injector trim code.

7. Click the "OK" button.

   • The injector trim code is loaded into the ECM.

8. Repeat the procedure for each cylinder, as required.

Registering New Fuel Injectors

Use the following Steps when an injector is moved to a different cylinder, or injectors are replaced.

1. Go to SIS.

2. Select "View More".

3. Select "Additional Service Information".

4. Select "C2.4, C3.3B" and "C3.8 Downloads".

5. Select ECU "Trim Data Registration".

6. Input the 6 or 7-digit code engine serial number. Refer to "General Information" to locate the serial number.

7. Click the button to select the engine.

8. Enter the new injector trim codes.

   Note: Following the above procedure will ensure that any future reflashing will flash the correct injector codes.

Registering a New DEF Injector Injection Timing, Serial Number, and Part Number

1. Record the DEF injector trim code & part number.

8. Input the 6 or 7-digit code engine serial number. Refer to "General Information" to locate the serial number.

9. Click the button to select the engine.

10. Enter the new DEF injector part number, Serial number, and injection timing.
    Show/hide table

    Illustration 13	g06075064

11. 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.

1. Establish communication between Cat ET and the engine ECM. Refer to Troubleshooting, "Electronic Service Tools", if necessary.

2. Select the following menu options on Cat ET:

   • Service

   • Calibrations

   • Diesel Exhaust Fluid Controller #1

   • Injector Code Calibration

4. Enter the new "DEF Injection Timing" Current Value.

5. Click the "Change" button.

Registering (Fuel) Injection Timing Correction

The following steps are to be followed when the fuel injection timing correction procedure has been performed and the engine ecm must be updates with the new value.

Note: This procedure is only performed if the crankshaft, gear case, crank gear, or flywheel is replaced. Refer to the following engine specific Special Instructions for determining Injection Timing Correction.
