LIN COMMUNICATION SYSTEM SYSTEM DESCRIPTION

  1. LIN COMMUNICATION SYSTEM DESCRIPTION

    The LIN communication system is used for communication between the components in the tables below. If communication cannot be performed through LIN communication because of an open in the communication lines or other reasons, the master control ECU of the relevant system will store a DTC. Refer to the table below about the communication bus lines and connected components.

    Tip:

    • Each component has a fail-safe function which activates to maintain the minimum performance of the system and protect the system.

    • In the following table, "○" indicates that the function applies, and "-" indicates that it does not.
