AUTOMATIC TRANSMISSION SYSTEM Pattern Select Switch Circuit

DESCRIPTION

The combination switch sends signals to the mirror switch through LIN communication, and the TCM sends signals to the mirror switch through CAN communication. When a combination switch signal is input into the TCM, the TCM sends a signal to the combination meter, which then illuminates the indicator.
