Seatback Mat does not Operate: Description

The seat vibration module receives power from the battery, and operates the rear seatback mat. Also, the seat vibration module and seat vibrator switch are controlled through LIN communication signals. If an error is detected, all system operations stop and only SW1 can be operated (all other switches cannot be operated). After the error is corrected, the system enters stop mode.
