DTC Descriptors
DTC P0CF9
- Control Pilot Charging Switch Performance
DTC P0D01
- Control Pilot Charging Ventilation Switch Performance
Circuit/System Description
The hybrid powertrain control module 2 has two internal switches used to modify the control pilot signal. The first internal switch modifies the control pilot signal to indicate to the electronic vehicle supply equipment that the vehicle is either ready or not ready to accept energy. The second internal switch modifies the control pilot signal to indicate to the electronic vehicle supply equipment whether indoor ventilation is required.
Conditions for Running the DTC
* The vehicle 12 V battery system voltage needs to be above 9 V.
* The cord set is disconnected and the charge port door is closed.
* Ignition ON.
* The diagnostics for DTC P0CF4-P0CF6 must have passed before these will run.
Conditions for Setting the DTC
The hybrid powertrain control module 2 measures a pilot signal voltage out of range for 10 seconds. This is an internal circuit voltage in the hybrid powertrain control module 2 and can not be measured.
Action Taken When the DTC Sets
* DTC P0CF9 and P0D01 are type A DTCs
* Disables the high voltage battery charging.
Conditions for Clearing the DTC
DTC P0CF9 and P0D01 are type A DTCs.

Circuit/System Verification
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. Verify that DTC P0CF4, P0CF5, or P0CF6 is not set.
• If any of the DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle.
2. DTC P0CF9 or P0D01 should not be set.
• If either of the DTCs are set, ignition OFF, disable the high voltage. Refer to High Voltage Disabling High Voltage Disabling. Replace the K114B hybrid powertrain control module 2.
Repair Instructions
Perform the Diagnostic Repair Verification Verification Tests after completing the diagnostic procedure.
