CAN COMMUNICATION SYSTEM TERMINALS OF ECU

Tech Tips

This section describes the standard CAN values for all CAN related components.


  1. CAN J/C


    1. CAN J/C connectors.

      Tech Tips


      • The connectors connected to the CAN J/C can be distinguished by the colors of the bus lines and the connecting side of the connector.

      • H3, H4 and H5 are interchangeable.
