Code P06B2 2015 Chevrolet Silverado 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, the 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 drive motor control module uses an internal 15 V reference power supply in order to operate the drive motor sensors and processor. This fault is handled inside the generator control module and no external circuits are involved.
The Diagnostic Trouble Code (DTC) will be set when the reference voltage is greater than 18.6 V for 1 second.
