Code U2624 Buick Description

Devices connected to the 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 scan tool does not communicate the Hybrid/EV Battery Interface Control Modules 12 on Battery Energy Control Module dedicated bus.
The Diagnostic Trouble Code (DTC) will set when there is no temperature report message from Hybrid/EV Battery Interface Control Modules 12 to Battery Energy Control Module within 4s.
