Interior courtesy lamps
To determine when to provide an interior courtesy lamps enable output, the BCU checks the following input conditions:
- Ignition state.
- Transit mode.
- Driver's door open.
- Passenger or rear door open.
The courtesy lamps operate at full brightness when they are first switched on. The BCU then gradually dims the lamps (fade-out) before completely switching them off. Fade-out occurs over a period of two seconds following the logical control signal to turn off the lights. When a door is opened, the BCU provides earth paths from the interior lamps, the load space lamp and the ignition switch illumination. The following table lists the courtesy lamps operation and duration for holding the lamps on that occurs after the BCU has detected a condition that signals the courtesy lamps should be switched on:
