DTC Descriptor
DTC P16F9
- Control Module Shutdown Performance

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.
* Ignition voltage is 8-18 V.

Conditions for Setting the DTC

The control module has detected the internal programmable logic device has not turned on or off correctly.

Action Taken When the DTC Sets

* DTC P16F9 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 P16F9 is a Type A DTC.

Diagnostic Aids

A low 12 V battery condition, an intermittent loss of power, or loss of communication to the drive motor generator power inverter module may set this DTC.

Circuit/System Verification

1. Verify that DTC P0562 is not set.

• If DTC is set, refer to DTC P0562 Hybrid/EV Controls.

2. If the DTC is set, program the T6 drive motor generator power inverter module. If the DTC resets, replace the T6 drive motor generator power inverter module.
