3. Reconnect the 12V battery. Refer to Battery Negative Cable Disconnection and Connection (See: Starting and Charging/Battery/Battery

Cable/Negative/Service and Repair/Battery Negative Cable Disconnection and Connection).

4. Ignition ON, retest for DTC P16F5.

瀚慖f the DTC resets, program the PIM with the latest software version and recheck for DTCs. If the DTC resets after programming or if the

PIM already contains the latest software version, replace the PIM.

Repair Instructions

Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

Control Module References (See: Testing and Inspection/Programming and Relearning) for PIM replacement, setup, and programming.

DTC Descriptor

DTC P16F6

- Control Module Range State Command

Circuit/System Description

This diagnostic applies to internal microprocessor integrity conditions within the hybrid powertrain control module (HPCM). The HPCM monitors

its ability to read and write to the memory. The HPCM processor monitors the data to verify that the commanded range state calculation is correct.

Conditions for Running the DTC

* The control module runs the program to detect an internal fault when the key is ON.

* Ignition voltage is 8-18V.

Conditions for Setting the DTC

The control module has detected the commanded transmission range state is not correct based upon internal calculations or by a comparison to

input or output torque conditions.

Action Taken When the DTC Sets

* DTC P16F6 is a Type A DTC.

* The HPCM commands the battery energy control module (BECM) to open the high voltage contactor relays.

Conditions for Clearing the DTC

DTC P16F6 is a Type A DTC.
