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

Driver Side Seat Belt Anchor does not Operate Manually

DESCRIPTION

When the shoulder belt anchorage switch's UP or DOWN switch are pressed, an UP or DOWN signal is sent to the front door ECU LH. 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 LH up or down.
