DTC Descriptor

DTC P16F2

-
Control Module Transmission Direction Range Switch

Circuit/System Description

The hybrid powertrain control module compares the internal mode switch requested direction to other data to verify that the indicated direction range switch calculation is correct.

Conditions for Running the DTC

* The ignition is ON.

* Ignition voltage is at least 9.5 V and no more than 18 V.

Conditions for Setting the DTC

Condition 1

* No internal mode switch direction switch DTCs are set.

* A valid internal mode switch direction indicated by the internal mode switch does not match the direction indicated by the hybrid powertrain control module software.

Condition 2

* No internal mode switch direction switch DTCs are set.

* Two valid internal mode switch directions are indicated at the same time.

Condition 3

* One internal mode switch direction switch circuit has failed.

* The hybrid powertrain control module calculates a transmission direction based upon the remaining internal mode switch circuits but it does not match the direction indicated by the hybrid powertrain control module software.

Condition 4

* Multiple internal mode switch directions and one internal mode switch direction switch circuit has failed.

* Based upon the remaining internal mode switch circuits the hybrid powertrain control module calculated two directions at the same time.

Condition 5

* More than one internal mode switch direction circuit has failed and the hybrid powertrain control module cannot calculate a transmission direction.

* Ignition voltage is 9.5-18 V.

Action Taken When the DTC Sets

* DTC P16F2 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 P16F2 is a Type A DTC.

Circuit/System Verification

1. Verify that DTC P181C, P181D, P181E, P181F, P183A, P183B, P183C, P183D, P183E, P184A or P184B is not set.

• If any of the DTCs are set, refer to DTC P181C-P181F, P183A-P183E, P184A, or P184B P181C.

2. Verify that DTC P16F2 is not set.

• If the DTC is set, program the hybrid powertrain control module. If the DTC resets, replace the T6 drive motor generator power inverter module.
