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.

  • Catalyst deterioration learning value is not registered.

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

  • Air fuel ratio sensor compensation learning value is not registered.*1

  • Injector compensation code

  • Injector pilot quantity learning value

  • Catalyst thermal deterioration value

  • Air fuel ratio sensor compensation 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 injector assembly is replaced, the new injector 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 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 injector assembly is replaced, perform pilot quantity learning. When the ECM is replaced, all of the existing injector pilot quantity learning values must be input into the new ECM.

  • When the catalyst converter is replaced, the new catalyst thermal deterioration value must be input into the ECM. When the ECM is replaced, the existing catalyst thermal deterioration value must be input into the new ECM.

Tip:

When replacing the ECM with a new one, if the injector compensation code, injector pilot quantity learning value and/or catalyst thermal deterioration 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 values and codes from the original ECM.

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

    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.

      Tip:
      • Each injector assembly 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 assembly.

      • 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.

CAUTION / NOTICE / HINT

Note:
  • After replacing the ECM, the new ECM needs registration (Click here) and initialization (Click hereНажмите здесь).

  • After replacing the exhaust manifold converter sub-assembly (DPF catalyst), clear the thermal deterioration data stored in the ECM.

Tip:

Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

PROCEDURE

  1. PERFORM 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.

  3. PERFORM LEARNING VALUES WRITE

    Tip:

    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.
