System Overview: Signals

The table below summarizes the input signals and output signals to and from the Closing velocity module (CVM). The signal type is divided into directly connected signals, CAN-, sensor-CAN-, and internal CAN communication. The illustration below reproduces the same information and Volvo component designations.
