ECD SYSTEM(for CCo), Diagnostic DTC:P062F

DTC Code DTC Name
P062F Internal Control Module EEPROM Error

DESCRIPTION

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory
P062F Internal Control Module EEPROM Error

When any condition below is met (1 trip detection logic):


  • Injector compensation code is not registered.

  • Wrong injector compensation code is registered.

  • Injector pilot quantity learning value is not registered.

  • Crank time compensation learning value is not registered.*1

  • Injector compensation code

  • Injector pilot quantity learning value

  • Crank time compensation learning value

  • ECM

 Comes on DTC stored

*1: When this malfunction occurs, the MIL does not illuminate.

Note


  • When a fuel injector is replaced, the new fuel injector compensation code must be input into the ECM. When the ECM is replaced, all of the existing fuel 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 assembly. 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.

  • When a fuel injector is replaced, perform pilot quantity learning. When the ECM is replaced, all of the existing fuel injector pilot quantity learning values must be input into the new ECM.

Tech Tips

When replacing the ECM with a new one, if the injector compensation code and/or injector pilot quantity learning value are not entered, DTC P062F will be stored.


  1. When replacing the ECM with a new one, input all learning values and codes into the new ECM as follows:


    1. Prior to replacing the ECM, use the GTS to read and save each learning value and code from the original ECM Click here.

    2. After installing a new ECM, input the saved learning values and codes into the new ECM using the GTS Click here.

    3. Turn the ignition switch off and turn the GTS off.

    4. Wait for at least 30 seconds.

    5. Turn the ignition switch to ON and turn the GTS on.

    6. Clear the DTC P062F stored in the ECM using the GTS Click here.

      Tech Tips


      • Each fuel 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 ON the ignition switch after replacing the ECM and other component(s), DTC P062F is stored. Manually clear the DTC upon completion of compensation code registration.

PROCEDURE


  1. LEARNING VALUES CONFIRMATION


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON and turn the GTS on.

      Note

      Do not start the engine.

    3. Enter the following menus: Powertrain / Engine and ECT / Utility / Learning values confirmation.

      Click here

      The pilot quantity learning values are set to the default values. B
      Except above C

      Tech Tips

      When the fuel injector pilot quantity learning values are set to the default values, "7FFF" is displayed.

  3. LEARNING VALUES WRITE

    Tech Tips

    When replacing the ECM, after performing "Learning Values Save" to save the learned values from the old ECM using the GTS and replacing the old ECM with a new one, "Learning Values Write" was not performed using the GTS causing this DTC to be output.


    1. Install the old ECM.

    2. Connect the GTS to the DLC3.

    3. Turn the ignition switch to ON and turn the intelligent GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Utility / Learning Values Save.

      Click here


      Powertrain > Engine > Utility
      Tester Display
      Learning Values Save

    5. Remove the old ECM.

    6. Install the new ECM.

    7. Enter the following menus: Powertrain / Engine and ECT / Utility / Learning Values Write.
