OVERVIEW
Operation of the interior lighting system, with the exception of the door and mirror lamps, is controlled by the CJB. Door and mirror lamp operation is controlled by the relevant door module.
In order to control the interior lighting system, the CJB receives inputs from the 4 door latch switches and the liftgate release motor. The system also interacts with the central locking system, illuminating the interior lamps and the mirror lamps on receipt of an unlock request. This request is transmitted to the CJB from the Radio Frequency (RF) receiver.
The front and rear roof mounted interior lamps contain a 3 position rocker switch. Automatic (Courtesy) operation of the lamps can be overridden by moving the switch to the 'always on' or 'always off' position.
If 'Courtesy' lighting is active and a hinged panel is left open, the CJB will extinguish all interior lamps after a period of 15 minutes. If a manual request for interior lighting has been made, the CJB will extinguish the lamps after a period of 30 minutes.
Pressing the light symbol on the remote handset will activate the 'Approach Lamp' feature. When activated, the CJB illuminates the mirror lamps and a number of exterior lamps. Refer to EXTERIOR LIGHTING .
On vehicles from 2009MY, the front interior lamp incorporates 2 map reading lamps. The front interior lamp is fitted with 2 additional switches which control each lamp and operate independently of the interior lighting functionality.
PRINCIPLES OF OPERATION
Operation and control of the interior lamps can be split into 3 main groups.
