Code U2613 Buick Description
This diagnostic is used to check the loss of communication with the Hybrid/EV Powertrain Control Module 2 on a high-speed General Motors Local Area Network (GMLAN) bus. The Battery Energy Control Module supervises a periodic serial data message to check the communication status of the Hybrid/EV Powertrain Control Module 2. If this message is not received within 400 ms, the Battery Energy Control Module increases its fail count. When this fail count is over X Cal Value (7) during Y Cal Value (10 samples), the diagnostic status of this code is set to Failed and transmitted over high voltage energy high-speed GMLAN bus to the Hybrid/EV Powertrain Control Module 2.
The Diagnostic Trouble Code (DTC) will set when a supervised periodic message that includes the transmitter device availability has not been received within 400 ms.
