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.

The hybrid powertrain control module has three internal 5 V reference circuits. Each internal reference circuit provides a 5 V reference for one or more sensors. A short to ground or short to voltage on one external 5 V reference circuit can affect all components connected to the same internal 5 V reference circuit.
