DTC P0D40, P1EDA, P1EDD or P1F03-P1F05

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 P0D40: Battery Charger Input Voltage Sensor Circuit High Voltage

DTC P1EDA: Battery Charger Converter Input Voltage Sensor 1 Circuit High Voltage

DTC P1EDD: Battery Charger Converter Input Voltage Sensor 2 Circuit High Voltage

DTC P1F03: Battery Charger Control Module Supply Voltage Performance

Circuit/System Description

The battery charger contains several internal sensor diagnostics that require the vehicle AC supply to be in the proper range. These diagnostics are internal battery charger diagnostics, but need the correct AC voltage to run properly.

Conditions for Running the DTC

•	The vehicle 12 V battery system voltage needs to be above 9 V.

•	The vehicle is connected to an AC supply.

Conditions for Setting the DTC

P0D40

The vehicle AC volt supply is greater 422 V AC.

P1EDA and P1EDD

The battery charger internal bulk voltage is greater than about 464 V DC. This is an internal measurement to the battery charger.

P1F03

The battery charger detects internal PBIAS voltage is greater than about 15 V DC. This is an internal measurement to the battery charger.

Action Taken When the DTC Sets

•	DTC P0D40, P1EDA, P1EDD or P1F03-P1F05 are type A DTCs.

•	Disables the vehicle high-voltage battery charging.

Conditions for Clearing the DTC

DTC P0D40, P1EDA, P1EDD or P1F03-P1F05 are type A DTCs.

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.
Verify DTC P0D2A 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.

If the DTC is set, 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.
