| 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 running | 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.
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).
MONITOR STRATEGY
| Required Sensors/Components | ECM |
| Frequency of Operation | Once per driving cycle |
CONFIRMATION DRIVING PATTERN
Connect the GTS to the DLC3.
Turn the engine switch on (IG) and turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the engine switch off and wait for at least 30 seconds.
Start the engine and warm it up.
Turn the engine switch off and wait for at least 15 seconds.
Start the engine.
Stop the engine and leave the vehicle for 60 minutes or more.
Turn the engine switch on (IG) and turn the GTS on.
Enter the following menus: Powertrain / Engine / Trouble Codes.
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.
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
Input the DTC: P2610.
Check the DTC judgment result.
| GTS Display | Description |
|---|---|
| NORMAL |
|
| ABNORMAL |
|
| INCOMPLETE |
|
| N/A |
|
Tech Tips
If the judgment result shows NORMAL, the system is normal.
If the judgment result shows ABNORMAL, the system has a malfunction.
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

CHECK WHETHER DTC OUTPUT RECURS (DTC P2610)
Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Clear the DTCs.
Turn the engine switch off and wait for at least 30 seconds.
Turn the engine switch on (IG).
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.
If no pending DTC is output, the repair has been successfully completed.
