P057c 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.
The Brake Pedal Position (BPP) sensor is used to sense the action of the driver application of the brake pedal. The BPP sensor provides an analog voltage signal that will increase as the brake pedal is applied. The BBP sensor contains two independent sensor assemblies. The hybrid powertrain control module located in the generator control module, and the body control module are connected to their respective sensor assembly. Each module provides a low reference signal and a 5-volt reference voltage to their respective BPP sensor. The hybrid powertrain control module also monitors the PRNDL state for inferred brake pedal application when transitioning in and out of the Park position.
