SFI SYSTEM(w/ Canister Pump Module), Diagnostic DTC:P2610

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

DTC SUMMARY

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory
P2610 ECM / PCM Internal Engine Off Timer Performance ECM internal malfunction (2 trip detection logic). ECM Comes on DTC stored
DTC No. Monitoring Item Detection Timing Detection Logic
P2610 Soak timer (built into ECM) Engine switch off 2 trip

DESCRIPTION

The soak timer operates after the engine switch is turned off. When a certain amount of time has elapsed after turning the engine 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.

B000XTWE01

MONITOR DESCRIPTION

If the soak timer activates the ECM even though only a short amount of time has elapsed since the engine 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 engine switch was turned off, the ECM determines that the soak timer is malfunctioning, illuminates the MIL and stores a DTC the next time the engine switch is turned on (IG).

Frequency of Operation Once per driving cycle

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 engine switch off and wait for at least 30 seconds.

  6. Start the engine and warm it up.

  7. Turn the engine switch off and wait for at least 15 seconds.

  8. Start the engine.

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

  10. Turn the engine switch on (IG).

  11. Turn the GTS on.

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

  13. 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.

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

  15. Input the DTC: P2610.

  16. 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.

    • If the judgment result shows INCOMPLETE or N/A, perform the Confirmation Driving Pattern and check the DTC judgment result again.

CAUTION / NOTICE / HINT

Tech Tips


  • 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.

PROCEDURE

  2. CLEAR DTC


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Clear the DTCs.

  3. CHECK WHETHER DTC OUTPUT RECURS (DTC P2610)


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

    2. Enter the following menus: Powertrain / Engine / Trouble Codes / Pending.


      Powertrain > Engine > Trouble Codes

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