Circuit/System Description

This is an internal fault detection of the drive motor generator power inverter module. This fault is handled inside the drive motor generator power inverter module and no external circuits are involved.

Conditions for Running the DTC

The control module runs the program to detect an internal fault when the Hybrid wake-up circuit is active.

Conditions for Setting the DTC

The control module has detected an internal malfunction.

Action Taken When the DTC Sets

•	DTCs P0BE6, P0BE7, P0BE8, P0BEA, P0BEB, P0BEC, P0BEE, P0BEF, P0BF0, P0BF2, P0BF3, P0BF4, P0BF6, P0BF7, P0BF8, P0BFA, P0BFB and P0BFC are Type B DTCs.

•	The drive motor generator power inverter module commands the battery energy control module to open the high voltage contactor relays.

Conditions for Clearing the DTC

DTCs P0BE6, P0BE7, P0BE8, P0BEA, P0BEB, P0BEC, P0BEE, P0BEF, P0BF0, P0BF2, P0BF3, P0BF4, P0BF6, P0BF7, P0BF8, P0BFA, P0BFB and P0BFC are Type B DTCs.
