DTC Descriptors
DTC P0D5B
- Battery Charger 14 V Output Power Performance
DTC P0D5C
- Battery Charger Hybrid/EV Battery Output Power Performance
DTC P1ECE
- Battery Charger Total Output Power Performance
DTC P1EFD
- Battery Charger Power Efficiency
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
P0D5B, P0D5C, P1ECE, and P1EFD
* The vehicle 12 V battery system voltage needs to be above 9 V.
* The vehicle is connected to an AC supply and the battery charger is charging.
* No out of range DTCs are present on any of the battery charger current or voltage sensors.
P1EFD
The battery charger needs to be charging at a minimum of 3 A high voltage DC current.
Conditions for Setting the DTC
The battery charger calculates a power output not within the proper range for 2 seconds.
Action Taken When the DTC Sets
* DTC P0D5B, P0D5C and P1ECE are type A DTCs.
* DTC P1EFD is a type B DTC.
* Disables the high voltage battery charging.
Conditions for Clearing the DTC
* DTC P0D5B, P0D5C and P1ECE are type A DTCs.
* DTC P1EFD is a type B DTC.
Diagnostic Aids
A possible cause of this DTC could be a faulty 14 V power module.

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.
1. Verify no other battery charger DTCs are set.
• If any other battery charger DTCs are set. Refer to Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle
2. Vehicle OFF, measure and record the 12 V battery voltage at the battery terminals. The battery voltage should stabilize between 12.4-12.8 V within a few minutes of turning the Vehicle OFF.
• If not within the specified range, refer to Battery Inspection/Test Battery Inspection/Test.
3. Vehicle in Service Mode, accessories OFF, measure and record the 12 V battery voltage at the battery terminals. The voltage should be at least 1 V greater than the voltage measured in step 1 but less than 15 V.
• If not within the specified range, refer to DC Power Conversion Test DC Power Conversion Test.
4. Vehicle OFF, disable the high voltage at the T18 battery charger. Refer to High Voltage Disabling High Voltage Disabling. Replace the T18 battery charger.
Repair Instructions
Perform the Diagnostic Repair Verification Verification Tests after completing the diagnostic procedure.
