Circuit/System Description

The generator control module also called the starter generator control module is comprised of the following three control modules; the hybrid powertrain control module, 14 volt power module and the drive motor control module. These three control modules are non serviceable and are part of the generator control module.

This is an internal fault detection of the generator control module. This fault is handled inside the generator control 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 drive motor control module is awake and the engine is off.

Conditions for Setting the DTC

* The control module has detected an internal malfunction.

* The motor phase U current is greater than 440 amps or less than -440 amps.

* The motor phase W current is greater than 440 amps or less than -440 amps.

Action Taken When the DTC Sets

* DTCs P0BE6, P0BE7, P0BE8, P0BEE, P0BEF, and P0BF0 are Type B DTCs.

* The generator control module operates in a reduced power mode.

* Regenerative breaking torque is reduced.

* Autostop and electric power assist are disabled.

Conditions for Clearing the DTC

DTCs P0BE6, P0BE7, P0BE8, P0BEE, P0BEF, and P0BF0 are Type B DTCs.
