DTC Descriptor
DTC P16F3
- Control Module Redundant Memory 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 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 stores identical data in two locations and compares the data to verify that the stored data is correct.

Conditions for Running the DTC

The system voltage is 8-18 V.

Conditions for Setting the DTC

The control module has detected that data identical when stored is not the same when retrieved.

Action Taken When the DTC Sets

* DTC P16F3 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 P16F3 is a Type A DTC.

Circuit/System Verification

1. Verify that DTC P0335, or any communication U-code DTC is not set.

• If DTC is set, refer to Diagnostic Trouble Code (DTC) List - Vehicle .

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

Repair Instructions
