Vehicle CAN Bus Monitor

Monitor vehicle CAN bus message traffic


The Vehicle CAN Bus Monitor displays live CAN message traffic.

Using this app, you can:

  • View message traffic for a specified CAN device and channel.

  • Save CAN bus messages to a log file.


The Vehicle CAN Bus Monitor does not support the CAN FD protocol.

You cannot programmatically configure the Vehicle CAN Bus Monitor. However, you can use it to independently visualize bus traffic generated on CAN channels by MATLAB® or Simulink® CAN blocks.

Open the Vehicle CAN Bus Monitor App

  • MATLAB Toolstrip: On the Apps tab, under Test and Measurement, click the app.

  • MATLAB command prompt: Enter canTool.
