The cargo compartment lighting is activated when the trunk lid is opened. The central electronic module (CEM) (4/56) receives a signal from the lock (3/78) in the trunk lid. The central electronic module (CEM) transmits the information via the Controller area network (CAN) to the rear electronic module (REM) (4/58) about the status of the trunk lid. A request for cargo compartment lighting is also sent from the upper electronic module (UEM) (4/70) to the rear electronic module (REM). The lamps (10/127-128 (S60/S80)) (10/173 (XC90)) are then powered directly from the rear electronic module (REM).
