Courtesy lights: Notes

The courtesy lights are located on the bottom of the doors. If the ignition switch is OFF (key removed), the lights will go on if one or more doors are opened. Courtesy lights stay on for 20 minutes (if a door is kept open) and then go out automatically. The lights are turned off when the doors are closed.

If the ignition is ON (+15 or +54), the courtesy lights stay on until all the doors are closed.

+30 current is fed to DICE for the courtesy lights. When DICE has received information via the bus, it turns on or off the courtesy lights. In other words, +30 current is supplied or not supplied, as the case may be, to the courtesy lights from pin 1 on the control module.
