DTC Descriptor
DTC P0D5E
- Battery Charger System High Voltage Present
Circuit/System Description
The battery charger will diagnose its own systems and determine when a fault condition is present. Diagnostics and system status is communicated from the battery charger to the hybrid/EV powertrain control module 2 through serial data. The hybrid/EV powertrain control module 2 is the host controller for DTC information.
Conditions for Running the DTC
Condition 1
The battery charger receives a discharge command from the hybrid/EV powertrain control module 2.
OR
Condition 2
The battery charger loses communication with the hybrid/EV powertrain control module 2.
Conditions for Setting the DTC
Condition 1
The battery charger control module measures a high voltage charging bus voltage greater than 60 V 1.5 seconds after receiving the discharge command from the hybrid/EV powertrain control module 2.
OR
Condition 2
The battery charger control module measures a high voltage charging bus voltage greater than 60 V 5 seconds after losing communication with the hybrid/EV powertrain control module 2.
Action Taken When the DTC Sets
DTC P0D5E is a type A DTC.
Conditions for Clearing the DTC
DTC P0D5E is a type A DTC.

Circuit/System Testing
Danger: Always perform the High Voltage Disabling procedure prior to servicing any High Voltage component or connection. Personal Protection Equipment (PPE) and proper procedures must be followed.
The High Voltage Disabling procedure will perform the following tasks:
* Identify how to disable high voltage.
* Identify how to test for the presence of high voltage.
* Identify condition under which high voltage is always present and personal protection equipment (PPE) and proper procedures must be followed.
Before working on any high voltage system, be sure to wear the following Personal Protection Equipment:
* Safety glasses with appropriate side shields when within 15 meters (50 feet) of the vehicle, either indoors or outdoors.
* Certified and up-to-date Class "0" Insulation gloves rated at 1000V with leather protectors.
- Visually and functionally inspect the gloves before use.
- Wear the Insulation gloves with leather protectors at all times when working with the high voltage battery assembly, whether the system is energized or not.
Failure to follow the procedures exactly as written may result in serious injury or death.
Danger: The Volt Battery Pack will utilize an exchange program. Please consult the most recent revision of bulletin/PI #PIP4841, available in Service Information (SI), for a list of approved Volt Battery Pack service procedures. Components that may be removed and serviced without exchanging the complete battery pack are identified in the bulletin/PI. Please contact the GM Technical Assistance Center (1-877-446-8227) if you have any questions.
1. Verify that DTC P0AA1, P0AD9, P0ADD, P0AE2, P0AE4, P0D0A, P0D11, P1EBC-P1EBF, P1EC0, or P1EC3-P1EC5 is not set.
• If the DTC is set, refer to DTC P0AA1, P0AD9, P0ADD, P0AE2, P0AE4, P0D0A, P0D11, P1EBC-P1EBF, P1EC0, or P1EC3-P1EC5 P0AA1
Note: The A4 hybrid/EV battery pack must not be at full charge to perform next test step.
3. Connect the drive motor battery charger cable. Vehicle ON, with a scan tool verify the Battery Charger High Output parameter drops below 60 V after disconnecting the drive motor battery charger cable
• If not the specified range, disable the high voltage at the A4 hybrid/EV battery pack, refer to High Voltage Disabling High Voltage Disabling. Replace the A4 hybrid/EV battery pack.
4. Disable the high voltage at the T18 battery charger, refer to High Voltage Disabling High Voltage Disabling. Replace the T18 battery charger.
