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 such as when there is an open or short in a communication line, 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.
HINT:
- Each component has a fail-safe function which operates in the event of a malfunction to protect the system and allow communication between other components to continue.
