Circuit/System Description

This is an internal fault detection of the hybrid powertrain control module. The hybrid powertrain control module is internal to the power inverter module, often referred to as the drive motor generator power inverter module, and is not serviced separately. This fault is handled inside the hybrid powertrain control module and no external circuits are involved.

Conditions for Running the DTC

* The vehicle is ON.
* The system voltage is greater than 9.5V.

Conditions for Setting the DTC

The control module has detected an internal malfunction.

Action Taken When the DTC Sets

* DTCs P0601-P0604, P0606, P061A, P061B, P062F, P1EB6, and P1EB7 are Type A DTCs.
* The hybrid powertrain control module requests the hybrid powertrain control module 2 to open the high voltage contactor relays.

Conditions for Clearing the DTC

DTCs P0601-P0604, P0606, P061A, P061B, P062F, P1EB6, and P1EB7 are Type A DTCs.
