DTC P2610: Powertrain Control Module (PCM) Internal Power Off Timer Malfunction: General Description

The powertrain control module (PCM) has a built-in power off timer that measures the duration of time the ignition switch is off. This measurement is used for evaporative emission (EVAP) leak detection and temperature assumption of the catalytic converter.

The CPU in the PCM accesses the power off timer when reading the measured duration. When the access process fails, a malfunction is detected and a DTC is stored. When an abnormality is found in the read data, a malfunction is detected and a DTC is stored.
