DTC P1EEF or P1EFE

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 P1EEF: Battery Charger 14 V 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

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.
    • Vehicle in Service Mode or the vehicle is connected to an AC supply.

Conditions for Setting the DTC

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 P1EEF and P1EFE are type A DTCs.
    • Disables the high-voltage battery charging.

Conditions for Clearing the DTC

DTC P1EEE, P1EEF and P1EFE are type A DTCs.

Diagnostic Aids

Connecting an external battery charger to vehicle while charging with drive motor battery charger cable can cause this DTC to set. Ensure customer did not have an external battery charger connected during plug-in charging attempt before proceeding with this diagnostic procedure

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.

  1. Verify DTC P0D44, P0D45, P0D49, P0D4A, P1EE9 or P1EEA is not set.
    2. ⇒If any of the DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle .
  2. Vehicle OFF, measure and record the 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.
    3. ⇒If not within the specified range, refer to Battery Inspection/Test .
  3. Vehicle OFF, disable the high voltage at the T18 battery charger. Refer to High Voltage Disabling . Disconnect the X2 harness connector at the T18 battery charger.
  4. Test for less than 10 Ω between the ground circuit terminal 1 and ground.
    5. ⇒If greater than the specified range, test the ground circuit for an open/high resistance.
  5. Test for B+ between the B+ circuit terminal 2 and earth.
    6. ⇒If less than the specified range, test the B+ circuit for a short to ground or an open/high resistance.
  6. If all circuits test normal, replace the T18 battery charger.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
