SFI SYSTEM(w/o EGR System), Diagnostic DTC:P2610

DTC Code DTC Name
P2610 ECM / PCM Internal Engine Off Timer Performance

DESCRIPTION

The soak timer operates after the power switch is turned off. When a certain amount of time has elapsed after turning the power switch off, the soak timer activates the ECM to perform malfunction checks which can only be performed after the engine is stopped. The soak timer is built into the ECM.

DTC No.

ECM / PCM Internal Engine Off Timer Performance

ECM internal malfunction (2 trip detection logic).

A290317E14

MONITOR DESCRIPTION

  1. While the power switch is off, the ECM monitors the synchronization of the soak timer and the CPU clock. If these two are not synchronized, the ECM interprets this as a malfunction, illuminates the MIL and stores the DTC.

  2. If the soak timer activates the ECM even though only a short amount of time has elapsed since the power switch was turned off, or if the soak timer does not activate the ECM even though a considerable amount of time has elapsed since the power switch was turned off, the ECM determines that the soak timer is malfunctioning, illuminates the MIL and stores a DTC the next time the power switch is turned on (IG).

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 power switch off and wait for at least 30 seconds.

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

  6. Put the engine in inspection mode (maintenance mode).

  7. Start the engine and warm it up.

  8. Turn the power switch off and wait for at least 15 seconds.

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

  10. Put the engine in inspection mode (maintenance mode).

    Click here

  11. Start the engine.

  12. Stop the engine and leave the vehicle for 60 minutes or more.

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

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

  15. Read the pending DTCs.

    Tip:

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

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

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

  17. Input the DTC: P2610.

  18. 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
    Tip:

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

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

CAUTION / NOTICE / HINT

Tip:

  • DTC P2610 is set if an internal ECM problem is detected. Diagnostic procedures are not required. ECM replacement is required.

  • 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.

  2. CHECK WHETHER DTC OUTPUT RECURS (DTC P2610)

    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

    4. Clear the DTCs.

      Click here

      Powertrain > Engine and ECT > Clear DTCs

    5. Turn the power switch off and wait for at least 30 seconds.

    6. Turn the power switch on (IG).

    7. Turn the GTS on.

    8. Drive the vehicle in accordance with the driving pattern described in the Confirmation Driving Pattern.

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

      Powertrain > Engine and ECT > Trouble Codes

    10. If no pending DTC is output, the repair has been successfully completed.
