DTC    P2610    ECM / PCM Internal Engine Off Timer Performance

for Preparation Click here


DESCRIPTION

The soak timer measures the engine off soak time, which is the time elapsed after the ignition 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.

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.

INSPECTION PROCEDURE

HINT:
  1. DTC P2610 is stored if an internal ECM problem is detected. Diagnostic procedures are not required. ECM replacement is necessary.
  2. 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.

1.REPLACE ECM
