192004521 - E2510 COURTESY LIGHTS - DESCRIPTION (5 doors, Electric sun roof)
Description
The front courtesy light includes three lamps with three control switches:
- the corresponding spot light can be switched on using external switches.
- the centre switch can be used to switch the centre light on or off and the switching on is also subject to a delay timer as described below.
The front courtesy light lighting delay is based on a logic managed by the Body Computer whilst the rear courtesy light is operated by the door control units in accordance with a logic transmitted by the Body Computer via the CAN:
- when one of the doors is opened, the courtesy light timing delay is 3 minutes;
- if another door is opened whilst the door is opened, the delay of three minutes starts again from zero;
- if a door remains open for longer than three minutes, the courtesy lights go out and remain off until one of the doors is opened again;
- if all the doors are closed during the 3 minute delay period, a second delay period of 20 seconds is activated and is interrupted if the ignition key is turned to the ON position;
- when the doors is opened using the remote control (or Passive Entry), the front courtesy lights come on for 20 seconds; the delay period is interrupted if the ignition key is turned ON;
- when the vehicle is closed with the door locking, the courtesy lights are switched off.
