DTC P0D3E or P0D3F

Diagnostic Instructions

•	Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.

•	Review Strategy Based Diagnosis for an overview of the diagnostic approach.

•	Diagnostic Procedure Instructions provides an overview of each diagnostic category.

DTC Descriptors

DTC P0D3E: Battery Charger Input Voltage Sensor Performance

DTC P0D3F: Battery Charger Input Voltage Sensor Circuit Low Voltage

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.

The DTCs listed above for the battery charger are internal measurements that verify the charger is performing properly. The battery charger measures voltages, currents, and temperatures and verifies they are within the proper range.

Conditions for Running the DTC

The vehicle needs to be connected to an AC supply and the battery charger is charging the vehicle.

Conditions for Setting the DTC

The battery charger detects low (less than 85V) or unstable supply voltage during charging.

Action Taken When the DTC Sets

•	DTC P0D3E and P0D3F are type A and B DTCs.

•	Disables high-voltage battery charging.

Conditions for Clearing the DTC

DTC P0D3E and P0D3F are type A and B DTCs.

Diagnostic Aids

Charging the vehicle with a wet drive motor battery charger cable can cause this DTC to set. Verify that the customer did not attempt to charge vehicle in the rain or extremely wet environment.

Low or unstable household voltage supply can cause this DTC to set. Verify with customer that domestic voltage was not fluctuating during charge attempt and that they are using a dedicated circuit.

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.

Before working on any high-voltage system, be sure to wear the following Personal Protection Equipment:

•	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.

Failure to follow the procedures exactly as written may result in serious injury or death.

Clear DTC, connect the drive motor battery charger cable to vehicle and known good domestic supply voltage.
Verify that DTC P0D3E or P0D3F is set.

⇒	If DTC is not set, the vehicle owner will have to attempt charge at home again. If the vehicle will not charge, they will need electrical supply serviced.

Verify that drive motor battery charger cable LEDs are not flickering.

⇒	If drive motor battery charger cable LEDs are flickering, replace drive motor battery charger cable.

Test for infinite resistance between the 110/220 V AC circuit terminals listed below and earth:

•	T18 battery charger terminal A X3

•	T18 battery charger terminal CX3

⇒	If less than the specified range, test the 110/220 V AC circuit for a short to ground.

Test for less than 10 Ω between the 110/220 V AC circuit terminals listed below:

•	T18 battery charger terminal A X3 and X98 hybrid battery charger receptacle E

•	T18 battery charger terminal C X3 and X98 hybrid battery charger receptacle A

⇒	If greater than the specified range, test the 110/220 V AC circuit for an open-circuit/high resistance.

Test for infinite resistance between the 110/220 V AC circuit at the T18 battery charger terminal A X3 and C X3.

⇒	If less than the specified range, test the 110/220 V AC circuits for a short-circuit between the circuits.

If all circuits test normal, replace the T18 battery charger.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
