DTC Descriptor
DTC P15F0
- Engine Torque Delivered Signal Message Counter Incorrect

Circuit/System Description

This diagnostic applies to internal microprocessor integrity conditions within 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. The hybrid powertrain control module monitors its ability to read and write to the memory. The hybrid powertrain control module processor monitors the data to verify that the indicated engine torque delivered calculation is correct.

Conditions for Running the DTC

* Vehicle is ON.
* The system voltage is 8-18 V.

Conditions for Setting the DTC

The control module has detected an internal malfunction.

Action Taken When the DTC Sets

* DTC P15F0 is a Type A DTC.
* The hybrid powertrain control module requests the hybrid powertrain control module 2 to open the high voltage contactor relays.

Conditions for Clearing the DTC

DTC P15F0 is a Type A DTC.
