DTC Descriptor
DTC P16F5
- Control Module Programmable Logic Device

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 drive motor generator power inverter module, and is not serviced separately. The hybrid powertrain control module and each motor control module utilize a programmable logic device to perform certain input and output functions. The hybrid powertrain control module monitors the ability of the programmable logic device to perform these functions.

Conditions for Running the DTC

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

Conditions for Setting the DTC

The control module has detected an internal programmable logic device malfunction.

Action Taken When the DTC Sets

* DTC P16F5 is a Type A DTC.
* The hybrid powertrain control module commands the battery energy control module to open the high voltage contactor relays.

Conditions for Clearing the DTC

DTC P16F5 is a Type A DTC.

Diagnostic Aids

An intermittent loss of battery power to the drive motor generator power inverter module may set this DTC.
