SFI SYSTEM(w/ Canister Pump Module), Diagnostic DTC:P062F44

DTC Code DTC Name
P062F44 Internal Control Module EEPROM Data Memory Failure

DESCRIPTION

The ECM monitors its internal operation and stores this DTC when it detects an internal malfunction.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P062F44 Internal Control Module EEPROM Data Memory Failure An ECM internal error (EEPROM) (1 trip detection logic). ECM Comes on DTC stored SAE Code: P062F

MONITOR DESCRIPTION

The ECM monitors its internal operation. If the internal operation is malfunctioning, the ECM illuminates the MIL and store this DTC.

CONFIRMATION DRIVING PATTERN


  1. Connect the GTS to the DLC3.

  2. Turn the engine switch on (IG).

  3. Turn the GTS on.

  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  5. Turn the GTS off.

  6. Turn the engine switch off.

  7. Disconnect the GTS.

  8. Disconnect the cable from the negative (-) battery terminal and wait for 1 minute.

  9. Connect the cable to the negative (-) battery terminal.

  10. Connect the GTS to the DLC3.

  11. Start the engine and wait 30 seconds or more.

  12. Turn the GTS on.

  13. Enter the following menus: Powertrain / Engine / Trouble Codes.

  14. Read the pending DTCs.

    Tech Tips


    • If a pending DTC is output, the system is malfunctioning.

    • If a pending DTC is not output, perform the following procedure.

  15. Enter the following menus: Powertrain / Engine / Utility / All Readiness.

  16. Input the DTC: P062F44.

  17. Check the DTC judgment result.

    GTS Display Description
    NORMAL

    • DTC judgment completed

    • System normal
    ABNORMAL

    • DTC judgment completed

    • System abnormal
    INCOMPLETE

    • DTC judgment not completed

    • Perform driving pattern after confirming DTC enabling conditions

    Tech Tips


    • If the judgment result is NORMAL, the system is normal.

    • If the judgment result is ABNORMAL, the system is malfunctioning.

CAUTION / NOTICE / HINT

Note

After turning engine switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work.

Tech Tips

Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE


  1. CLEAR DTC


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Clear the DTC.


      Powertrain > Engine > Clear DTCs

    5. Turn the engine switch off.
