● The tailgate control unit master J605 communicates with the tailgate control unit slave J756 via a single-
wire bus specified by systems supplier Valeo (no LIN bus).
● Via the wake-up line, the tailgate control unit master J605 can wake up the tailgate control unit slave J756.
This is the case if the convenience CAN bus is reactivated in Sleep Mode, or if the interior tailgate release is
operated while the convenience CAN bus is in Sleep Mode. The slave tailgate control unit wakes up the
master control unit J605 if manual operation of the tailgate is detected .
● The function block of the rear right power latching motor shows two sensors. They have the task of
monitoring the two end positions of the power latching system and informing the convenience system
central control unit when they are reached.
