Code P1A6F 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 eAssist hybrid system has the ability to crank and start the engine using two different methods. The first method is a conventional 12-volt system. On every initial start up the conventional 12-volt starter and 12-volt battery are used to crank and start the engine.
The second starting method uses the 86-volt hybrid/EV battery pack and the starter/generator also called the drive motor. The drive motor is a 3 phase AC induction machine. This device not only serves as an 86-volt AC generator but is also used to provide engine power assist and to start the engine when in auto-stop mode. If the system is in the auto-stop mode and fails to restart with the drive motor, the 12-volt conventional starter will automatically be engaged to start the engine.
The Diagnostic Trouble Code (DTC) will be set when the Hybrid/EV Powertrain Control Module 1 detects that an autostart failed to take place successfully.
