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 has 1 current sensor for input current measurements. This diagnostic checks the input current sensor. The current sensor is internal to the 14 V power module and is not serviced separately from the generator control module.
