DTC No. Monitoring Item Malfunction Detection Condition Trouble Area Detection Timing Detection Logic
P2610 Soak timer (built into ECM) ECM internal malfunction (2 trip detection logic). ECM Engine running 2 trip

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.

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 ON.

Tech Tips


  • DTC P2610 is stored 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.
