СИСТЕМА ECD, Diagnostic DTC:P2610

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

DESCRIPTION

The soak timer measures the engine off soak time, which is the time elapsed after the engine switch has been turned off. The ECM uses the engine off soak time to monitor some systems for malfunction detection.

If necessary, the soak timer may activate the ECM to perform certain malfunction checks that can only be performed after the engine stopped. The soak timer is built into the ECM.

MONITOR DESCRIPTION

The ECM compares the soak timer value with the ECM timer value from turning the ignition switch off until the EFI-MAIN relay turned off. If the difference has deviated more than the allowable range, the ECM determines that there is a malfunction and illuminates the MIL in the next step.

CAUTION / NOTICE / HINT

Note:
  • Inspect the fuses of circuits related to this system before performing the following procedure.

  • When replacing the ECM, perform ECM Initialization and Registration.

Tip:
  • DTC P2610 is stored if an internal ECM problem is detected. Diagnostic procedures are not required. ECM replacement is necessary.

  • Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

  2. CHECK WHETHER DTC OUTPUT RECURS

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON and turn the GTS on.

    3. Clear the DTCs.

      Powertrain > Engine and ECT > Clear DTCs
    4. Turn the ignition switch off and wait 30 seconds or more.

    5. Start the engine.

    6. Turn the ignition switch off and wait 30 seconds or more.

    7. Turn the ignition switch to ON and turn the GTS on.

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

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