System Overview: Signals

WARNING: This page is about a different variant/trim than selected.

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.
