P2610 Soak timer (built into ECM) There is an ECM internal malfunction (2 trip detection logic). ECM Engine running 2 trip

DESCRIPTION

The soak timer operates after the ignition switch is turned off.

MONITOR DESCRIPTION

While the engine is running, the ECM monitors the synchronization of the soak timer and CPU clock. If these two are not synchronized, the ECM interprets this as a malfunction, illuminates the MIL and stores the DTC.

INSPECTION PROCEDURE

Tech Tips


  • 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 intelligent tester. 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, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.
