DTC Descriptor

DTC P0D1F: Control Module Date/Time Synchronization Performance

The hybrid/EV powertrain control module 2 monitors the date and time data it receives from the radio. This time information is used to ensure the module's internal clock is synchronised to the customer's local time. The Time of Day Charging feature utilises this internal clock to keep track of time and alarms for delayed charging modes. If this radio time data is received during a drive cycle, the system is considered synchronised.
