System Description

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 a break in the communication lines or some other reason, the master control ECU of the relevant system stores DTCs. Refer to the tables below about the communication bus lines and connected components.

HINT:

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.
