DTC Descriptors
DTC P1EEE
- Battery Charger 14V Output Voltage Performance
DTC P1EEF
- Battery Charger 14V Converter Output Power Regulation Performance
DTC P1EFE
- Battery Charger Reverse Polarity Protection Circuit Performance
Circuit/System Description
The battery charger 14 V output circuit is connected to the vehicle 12 V system. The battery charger monitors the 14 V output for proper current and voltage conditions. The battery charger has the ability to drive the voltage to 14 V.
Conditions for Running the DTC
P1EEE
* The vehicle 12 V battery system voltage needs to be above 9 V.
* The vehicle is connected to an AC supply.
P1EEF
* The vehicle 12 V battery system voltage needs to be above 9 V.
* P0D44, P0D45, P0D49, P0D4A, P1EE9, or P1EEA should not be set.
* The vehicle is connected to an AC supply and the battery charger is charging.
P1EFE
* The vehicle 12 V battery system voltage needs to be above 9 V.
* Ignition ON or the vehicle is connected to an AC supply.
Conditions for Setting the DTC
P1EEE
The battery charger detects the 14 V output is less than 3 V or greater than 18 V.
P1EEF
The battery charger actual 14 V output voltage or current is out of the allowable tolerance compared with the commanded output voltage or current. This is measured internal to the battery charger.
P1EFE
The battery charger 14 V reverse polarity protection relay state does not match the commanded state. This internal to the battery charger.
Action Taken When the DTC Sets
* DTC P1EEE, P1EEF, P1EFE are type A DTCs.
* Disables the high voltage battery charging.
Conditions for Clearing the DTC
DTC P1EEE, P1EEF, P1EFE are type A DTCs.

Circuit/System Verification
1. Verify DTC P0D44, P0D45, P0D49, P0D4A, P1EE9, or P1EEA is not set.
• If there are battery charger voltage or current DTCs set, refer to Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle.
2. Ignition OFF, measure and record the battery voltage at the battery terminals. The battery voltage should stabilize between 12.4-12.8 V within a few minutes of turning the ignition OFF.
• If not within the specified range, refer to Battery Inspection/Test Battery Inspection/Test.
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. Ignition OFF, disconnect the harness X1 harness at the T18 battery charger. Test for less than 10 ohm between the ground circuit terminal 1 and ground.
• If greater than the specified range, test the ground circuit for an open/high resistance.
2. Test for 3-18 V between the B+ circuit terminal 2 and ground.
• If less than the specified range, test the B+ circuit for a short to ground or an open/high resistance.
• If greater than the specified range, test the B+ circuit for a short to high voltage.
3. If all circuits test normal, disable the high voltage. 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.
