POWER SHOULDER BELT ANCHORAGE SYSTEM Driver Side Seat Belt Anchor does not Operate Manually

DESCRIPTION

When the shoulder belt anchor switch's UP or DOWN switch is pressed, an UP or DOWN signal is sent to the front door ECU (driver side). Then the signal is sent to the rear junction block ECU through CAN communication. Based on the received signal, the rear junction block ECU moves the shoulder belt anchor (driver side) up or down.
