DTC Descriptors
DTC P1EE6
- Battery Charger AC Not Present

Diagnostic Fault Information






Circuit/System Description

The hybrid battery charger receptacle is connected to the battery charger through two 110/220 V AC circuits and one ground circuit. The battery charger receives serial data message from the hybrid powertrain control module 2 that the drive motor battery charger cable has been connected and then monitors the two 110/220 V AC circuits for proper voltage.

Conditions for Running the DTC

* The vehicle 12 V battery system voltage needs to be above 9 V.
* The drive motor battery charger cable is connected.
* The diagnostics for P0D3F, P0D40, P1EE7, P1EE8, P0D3E, P1ECE, P0D5C, P0D5B, P16C4, P1EFD must have passed.

Conditions for Setting the DTC

The battery Charger AC input Voltage is below 5 V.

Action Taken When the DTC Sets

* DTC P1EE6 is a type A DTC.
* Disables the vehicle high voltage battery charging.

Conditions for Clearing the DTC

DTC P1EE6 is a type A DTC.

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 15 meters (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 with leather protectors 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. Clear DTC, connect a known good drive motor battery charger cable to vehicle and household supply voltage.
2. Verify DTC P1EE6 is set.

• If DTC P1EE6 is not set, replace customer's drive motor battery charger cable.

3. Vehicle OFF, disable the high voltage at the T18 battery charger. Refer to High Voltage Disabling High Voltage Disabling.
4. Disconnect the X3 harness connector at the T18 battery charger and harness connector at the X98 hybrid battery charger receptacle.
5. Test for infinite resistance between the 110/220 V AC circuit terminals listed below and ground:

* 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.

6. Test for less than 10 ohm 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/high resistance.

7. 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 between the circuits.

8. If all circuits tests normal, replace X98 hybrid battery charger receptacle. If the DTC resets, replace the T18 battery charger.
