7GR-FKS ENGINE CONTROL SFI SYSTEM P261029 ECM/PCM Engine Off Timer Performance Signal Invalid

DESCRIPTION

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

P261029	ECM/PCM Engine Off Timer Performance Signal Invalid	ECM internal malfunction (2 trip detection logic).	ECM	Comes on	DTC stored	SAE Code: P2610

MONITOR DESCRIPTION

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

MONITOR STRATEGY

Required Sensors/Components	ECM
Frequency of Operation	Once per driving cycle

CONFIRMATION DRIVING PATTERN

Connect the GTS to the DLC3.

Turn the ignition switch to ON.

Turn the GTS on.

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

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

Start the engine and warm it up.

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

Turn the ignition switch to ON.

Turn the GTS on.

10.

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

11.

Read the pending DTCs.

HINT:: ·

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

·

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

12.

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

13.

Input the DTC: P261029.

14.

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

HINT:: ·

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

·

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

CAUTION / NOTICE / HINT

HINT:: ·

DTC P261029 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

1.REPLACE ECM

Replace the ECM.

2.CHECK WHETHER DTC OUTPUT RECURS (DTC P261029)

Connect the GTS to the DLC3.

Turn the ignition switch to ON.

Turn the GTS on.

Clear the DTCs.

Powertrain > Engine > Clear DTCs: 50002 372

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

Turn the ignition switch to ON.

Turn the GTS on.

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

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

Powertrain > Engine > Trouble Codes: 50001 372

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