SFI SYSTEM, Diagnostic DTC:P062F

DTC Code DTC Name
P062F Internal Control Module EEPROM Error

DESCRIPTION

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

DTC No. DTC Detection Condition Trouble Area
P062F An ECM internal error (EEPROM) (1 trip detection logic). ECM

MONITOR DESCRIPTION

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

CONFIRMATION DRIVING PATTERN


  1. Connect the Techstream to the DLC3.

  2. Turn the power switch on (IG) and turn the Techstream on.

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

  4. Turn the Techstream off.

  5. Turn the power switch off.

  6. Disconnect the Techstream.

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

  8. Connect the cable to the negative (-) auxiliary battery terminal.

  9. Connect the Techstream to the DLC3.

  10. Turn the power switch on (IG) and turn the Techstream on.

  11. Put the engine in inspection mode (maintenance mode) Click here.

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

  13. Enter the following menus: Powertrain / Engine and ECT / 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 and ECT / Utility / All Readiness.

  16. Input the DTC: P062F.

  17. Check the DTC judgment result.

    Techstream 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
    N/A

    • Unable to perform DTC judgment

    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    Tech Tips


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

    • If the judgment result shows ABNORMAL, the system has a malfunction.

  18. If the judgment result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and check for permanent DTCs Click here.

    Tech Tips


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

    • If no permanent DTC is output, the system is normal.

INSPECTION PROCEDURE

Note


  • There is a possibility that the DTC P062F is issued from the ECUs of the ECM and power management control ECU.

    Use Techstream to conduct a health check to confirm which ECU the DTC is issued from and then inspect the related system.

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

Tech Tips

Read freeze frame data using the Techstream. 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. READ OUTPUT DTC (DTC P062F)


    1. Connect the Techstream to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the Techstream on.

    4. Clear the DTCs Click here.

    5. Turn the power switch off and turn the Techstream off.

    6. Disconnect the Techstream.

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

    8. Connect the cable to the negative (-) auxiliary battery terminal.

    9. Connect the Techstream to the DLC3.

    10. Turn the power switch on (IG).

    11. Turn the Techstream on.

    12. Put the engine in inspection mode (maintenance mode) Click here.

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

    14. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

    15. Read the DTCs.
