Luggage compartment lighting
| Luggage compartment lighting |
The luggage compartment lighting is turned on/off when the boot lid is opened and closed respectively.
| • |
If the ignition is OFF (+15 and +54) or the key removed and the lid is opened, the lighting will stay on for 20 minutes before turning off automatically.
|
|
| • |
If the ignition is ON (+15 and +54) and the lid is opened, the lighting will go on until the lid is closed again.

The power supply +30 to the luggage compartment lighting is fed via fuse 4 and DICE pin 24. The control module controls the function together with TWICE.
When the boot lid is opened, the light switch (56) in the lid lock closes. The switch is connected to TWICE, which detects whether the lid is open or closed.
TWICE outputs information about the lid status (OPEN/CLOSED) to the instrument bus and the information is read by DICE. If the lid is open, power is supplied from DICE pin 2 to the lamp (55). If the switch on the luggage compartment lamp is not closed, the lamp will not light, irrespective of the lid status according to TWICE.
When the ignition is ON, an open boot lid is indicated on the main instrument unit. The MIU receives information to light the indicator from the bus.
| Diagnosis |
The output has an overload protection that shuts the output off if the load is too high. This activates DTC B1235.
DTCs are not generated if the voltage is below 11V or during diagnostic communication.
