U182A BUICK MeaningDevices connected to the powertrain high-speed General Motor Local Area Network (GMLAN) serial data circuits monitor for serial data communications during normal vehicle operation. Operating information and commands are exchanged among the devices. The devices have prerecorded information about what messages are needed to be exchanged on the serial data circuits, for each virtual network. The messages are supervised and also, some periodic messages are used by the receiver device as an availability indication of the transmitter device. Each message contains the identification number of the transmitter device.
The Battery Energy Control Module is internal to the Hybrid/EV Powertrain Control Module 2. Communication diagnostics for the serial data, including device power and ground as well as the wakeup circuits for the K16 Battery Energy Control Module is diagnosed from external sources only to the Hybrid/EV Powertrain Control Module 2 connector because any circuit fault condition within the Hybrid/EV Powertrain Control Module 2 will cause a complete replacement.
The Diagnostic Trouble Code (DTC) will set when a supervised periodic message that includes the transmitter device availability has not been received.
