ECD SYSTEM (w/o DPF) REGISTRATION

REGISTRATION
Note
- When an injector is replaced, the injector's compensation code must be input into the ECM. When the ECM is replaced, all of the existing injector compensation codes must be input into the new ECM.
- Injector compensation codes are unique, 30 digit, alphanumeric values printed on the head portion of each injector. If an incorrect injector compensation code is input into the ECM, the engine assembly may rattle or engine idling may become rough. In addition, engine failure may occur and the life of the engine may be shortened.
1. AFTER REPLACING INJECTOR(S) WITH NEW ONE(S), INPUT COMPENSATION CODE(S) OF INJECTOR(S) INTO ECM AS FOLLOWS
  Tech Tips
  - Each injector has different fuel injection characteristics. In order to optimize the fuel injections, the ECM uses the compensation codes to balance the different fuel injections between each injector.
  - When you first turn the ignition switch ON after replacing the ECM or an injector(s), DTC P1601 is set. This is to inform you that an injector compensation codes(s) is/are required to be registered. Manually clear the DTC upon completion of the compensation code registration.
  1. Input the compensation code(s), which is/are imprinted on the head portion(s) of the new injector(s), to the intelligent tester.
  2. Input the new compensation code(s) into the ECM using the tester.
  3. Turn the tester OFF and turn the ignition switch OFF.
  4. Wait for at least 30 seconds.
  5. Turn the ignition switch to ON and turn the tester ON.
  6. Clear DTC P1601 stored in the ECM using the tester.
2. REGISTER COMPENSATION CODE:
  1. Connect the intelligent tester to the DLC3.
  2. Turn the ignition switch ON.
  3. Turn the tester ON.
    
    Note
    
    Do not start the engine.
    
    Tech Tips
    
    The injector compensation code is printed on the head portion of each injector.
  4. Select the following menu items: Powertrain / Engine / Utility / Injector Compensation.
  5. Press Next.
  6. Press Next again to proceed.
  7. Select "Set Compensation Code".
  8. Press Next.
  9. Select the number of the cylinder corresponding to the injector compensation code that you want to read.
  10. Press Next.
  11. Register compensation code.
    
    Press Input.
    
    Manually input the cylinder's compensation code using the keyboard on the tester screen. The code is a 30 digit, alphanumeric value printed on the injector's head portion.
    
    Tech Tips
    
    Each injector compensation code is unique. The correct compensation code must be input into each cylinder selected on the tester.
    
    Confirm that the compensation code for the selected cylinder is correct, and then press OK.
  12. Check that the compensation code displayed on the screen is correct by comparing it with the 30 digit alphanumeric value on the head portion of the injector.
    
    Note
    
    If an incorrect injector compensation code was input into the ECM, the engine may rattle or engine idling may become rough. In addition, engine failure may occur and the life of the engine may be shortened.
    
    Tech Tips
    
    If a wrong compensation code was input or read, return to the Input Value screen by pressing Input.
    
    The saving process may fail due to a problem with the wire harness or a bad connection with the DLC3. Check the wire harness and the DLC3 connection. If no problem is found with either, the ECM may be malfunctioning. Check the ECM and repeat this operation.
  13. Press Next to set the compensation code to the ECM.
    
    Tech Tips
    
    If the setting process fails, the compensation code may be incorrect. Check the compensation code again.
    
    If the input compensation code is correct, a problem with the wire harness or a bad connection with the DLC3 may cause the failure. Check the wire harness and the DLC3 connection. If no problem is found with either, the ECM may be malfunctioning. Check the ECM and restart this operation.
  14. If you want to continue with other compensation code registrations, press Next. To finish the registration, press Cancel.
  15. Turn the ignition switch OFF and then turn the tester OFF.
  16. Wait for at least 30 seconds.
  17. Turn the ignition switch ON and then turn the tester ON.
  18. Clear DTC P1601 stored in the ECM using the tester.
READING REGISTERED DATA
Note
- When an injector is replaced, the injector's compensation code must be input into the ECM. When the ECM is changed, all of the existing injector compensation codes must be input into the new ECM.
- Injector compensation codes are unique, 30 digit, alphanumeric values printed on the head portion of each injector.

DESCRIPTION OF VIN

Note

The Vehicle Identification Number (VIN) must be input into the replacement ECM.

Tech Tips

The VIN is a 17-digit alphanumeric number. An intelligent tester is required to register the VIN.

This registration section consists of two parts, Read VIN and Write VIN.
1. Read VIN: Explains the VIN reading process in a flowchart. This process allows the Vin stored in the ECM to be read, in order to confirm that the two VINs, provided with the vehicle and stored in the vehicle's ECM, are the same.
2. Write VIN: Explains the VIN writing process in a flowchart. This process allows the VIN to be input into the ECM. If the ECM is changed, or the VIN and VIN do not match, the VIN can be registered, or overwritten in the ECM by following this procedure.
READ VIN
1. Confirm the vehicle VIN.
2. Connect the intelligent tester to the DLC3.
3. Turn the ignition switch to ON.
4. Turn the tester ON.
5. Select the following menu items: Powertrain / Engine / Utility / VIN.
WRITE VIN
1. Confirm the vehicle VIN.
2. Connect the intelligent tester to the DLC3.
3. Turn the ignition switch to ON.
4. Turn the tester ON.
5. Select the following menu items: Powertrain / Engine / Utility / VIN.
