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 power 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.
DTC No. | DTC Detection Condition | Trouble Area |
---|---|---|
P2610 | ECM internal malfunction (2 trip detection logic). | ECM |
MONITOR DESCRIPTION
While the engine is running, 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.
MONITOR STRATEGY
Required Sensors/Components | ECM |
Frequency of Operation | Once per driving cycle |
CONFIRMATION DRIVING PATTERN
Connect the GTS to the DLC3.
Turn the power switch on (IG) and turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the power switch off and wait for at least 30 seconds.
Turn the power switch on (IG) and turn the GTS on.
Put the engine in inspection mode (maintenance mode) Click here.
Start the engine.
Idle the engine for 10 minutes or more.
Enter the following menus: Powertrain / Engine and ECT / 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 and ECT / 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.

CHECK WHETHER DTC OUTPUT RECURS (DTC P2610)
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Turn the GTS on.
Clear the DTCs Click here.
Turn the power switch off and wait for at least 30 seconds.
Turn the power switch on (IG).
Turn the GTS on.
Put the engine in inspection mode (maintenance mode) Click here.
Start the engine and wait for 10 minutes or more.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes / Pending.
If no pending DTC is output, the repair has been successfully completed.
