SFI SYSTEM, Diagnostic DTC:P062F

DTC Code DTC Name
P062F Internal Control Module EEPROM Error

DESCRIPTION

The ECM monitors its internal operation and it 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.

MONITOR STRATEGY

Required sensors/Components (Main) ECM
Required sensors/Components (Related) -
Frequency of operation Once per driving cycle

CONFIRMATION DRIVING PATTERN


  1. Connect the GTS to the DLC3.

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

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

  4. Turn the GTS off.

  5. Turn the power switch off.

  6. Disconnect the GTS.

  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 GTS to the DLC3.

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

    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
    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.

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

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. READ OUTPUT DTC (DTC P062F)
