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. Overly high AC supply voltages may cause one or more of these DTCs to set.
Conditions for Running the DTC
P0D40, P1EDA, P1EDD, P1F03-P1F05
* The vehicle 12 V battery system voltage needs to be above 9 V.
* The vehicle is connected to an AC supply.
P1EFA
* The vehicle 12 V battery system voltage needs to be above 9 V.
* The vehicle is connected to an AC supply and battery charging is charging the high voltage battery supply.
P1EFB
* The vehicle 12 V battery system voltage needs to be above 9 V.
* The vehicle is connected to a 240 V AC supply and battery charging is charging the high voltage battery supply.
Conditions for Setting the DTC
P0D40
The vehicle AC volt supply is greater 422 V AC.
P1EDA, P1EDD, P1F05
The battery charger internal bulk voltage is greater than about 464 V DC. This is an internal measurement to the battery charger.
P1EFA, P1EFB
The battery charger detects an internal over current condition. 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.
P1F04
The battery charger internal bulk voltage is greater than 290 V DC. This is an internal measurement to the battery charger.
Action Taken When the DTC Sets
* DTC P0D40, P1EDA, P1EDD, P1EFA, P1EFB, or P1F03-P1F05 are type A DTCs.
* Disables the vehicle high voltage battery charging.
Conditions for Clearing the DTC
DTC P0D40, P1EDA, P1EDD, P1EFA, P1EFB, 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 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 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 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. Connect the vehicle AC supply. Verify the scan tool Battery Charger Input parameter is less than 265 V AC.
• If greater than the specified range, verify the AC supply is within 85-265 VAC.
2. If all circuits test normal, replace the T18 battery charger.
Repair Instructions
Perform the Diagnostic Repair Verification Verification Tests after completing the diagnostic procedure.
