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

Front Passenger Side Seat Belt Anchor does not Operate Manually

DESCRIPTION

When the up or down switch of the shoulder belt anchorage switch is pressed, an UP or DOWN signal is sent to the front door ECU RH. Then the signal is sent to the rear junction block ECU through CAN communication. Based on the received signal, the rear junction block ECU operates the shoulder belt anchor motor RH and moves the shoulder belt anchor RH up or down.
