DTC P0D5B, P0D5C, P1ECE or P1EFD
Diagnostic Instructions
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 conditions under which high voltage is always present and personal protection equipment (PPE) and proper procedures must be followed. |
| • | Safety goggles with appropriate side shields when within 15 metres (50 feet) of the vehicle, either indoors or outdoors. |
| • | Certified and up-to-date Class "0" Insulation gloves rated at 1000 V 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 energised or not. |
- Verify that no other battery charger DTCs are set.
- Vehicle OFF, measure and record the 12 V battery voltage at the battery terminals. The battery voltage should stabilise between 12.4-12.8 V within a few minutes of turning the Vehicle OFF.
- 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.
- Vehicle OFF, disable the high voltage at the T18 battery charger. Refer to High Voltage Disabling . Replace the T18 battery charger.
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
