| | Interior lighting | The car's interior lighting is controlled by the ICE control module which grounds the roof lamps, reading lamps and switch. The interior lighting is supplied with +30 voltage via fuse 4. The interior lighting is switched on when a door is opened, causing the door switch to close and ground pin 44 (driver's door) or pin 67 (passenger doors) of the ICE control module. The ICE grounds the lamps according to the position of the switch: Position 1: (front position) Both roof lamps on regardless of the ignition switch position or whether the ignition key is inserted or not, irrespective of the position of the door. Position 2: (middle position) Both roof lamps come on when a door is opened or the key is removed from the ignition switch. (Remain on as long as the door is open or for a maximum of 20 seconds if the door is closed. The interior lighting then dims.) Position 3: (rear position) Only the rear roof lamp comes on regardless of the ignition switch position or whether the ignition key is inserted or not, irrespective of the position of the door. The ICE control module also controls the timing of the interior lighting. Reading lamps The reading lamps can always be operated, regardless of the position of the switch or the position of the ignition switch and whether the doors are open or closed.
