DTC Descriptor

DTC P0D1F

-
Control Module Date/Time Synchronization Performance

Circuit/System Description

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

Conditions for Running the DTC

The vehicle needs to go from Vehicle OFF to Vehicle in Service Mode to start the diagnostic.

Conditions for Setting the DTC

The vehicle is driven for more than 5 consecutive drive cycles where trip distance exceeds 15 Kilometers, and the date and time were unavailable from the OnStar Module.

Action Taken When the DTC Sets

* DTC P0D1F is a type C DTC.

* On the Navigation screen "Default Charge Mode: Immediately" is displayed.

* The battery charger Time Of Day charging option is disabled, and charging mode is set to IMMEDIATE.

Conditions for Clearing the DTC

DTC P0D1F is a type C DTCs.

Circuit/System Verification

1. Verify no OnStar DTC's are set.

• If any OnStar DTC's are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle.

Note:
The vehicle needs to be in an open, outside area where a cellular call can be successfully placed and GPS data can be received from satellites.

2. Verify the scan tool Telematics Communication Interface Control Module/Data Display/GPS Data/Second parameter is incrementing.

• If seconds are not incrementing, refer to No Global Positioning System (GPS) Reception No Global Positioning System (GPS) Reception.

3. Replace the K114B hybrid/EV powertrain control module 2.
