Circuit/System Description

The generator control module also called the starter/generator control module is comprised of the following three control modules; the hybrid/EV powertrain control module 1, 14 V power module and the drive motor control module. These three control modules are non serviceable and are part of the generator control module.

The 14 V power module supplies the energy that flows between the high voltage (86 V) direct current (DC) and low voltage (14 V) DC to charge the 12 V battery and power accessories. The 14 V power module receives a wake-up signal from the hybrid/EV powertrain control module 1 when the ignition/vehicle is switched to On. After a successful initialization, the 14 V power module receives an enable command from the hybrid/EV powertrain control module 1 to begin power conversion.
