If the ignition is OFF (or the key removed) and the glove box is opened, the light will stay on for 20 minutes before turning off automatically. The
light will go on again if one of the doors is opened or if the ignition is turned ON.
-
If the ignition is ON (+15 and +54) and the glove box is opened, the light will stay on until the lid is closed again.
The power supply to the glove box light is common with that to the reading lights.
The lighting goes out while the engine is started (starter motor cranks). However, it does not stay off for more than 20 seconds.
To prevent unnecessary loading on the battery when the starter motor is activated, DICE turns the lighting off. When the ignition switch is moved from
the ST position to ON, DICE turns the lighting on again. The off period is limited to 20 seconds for safety reasons, so that the lighting will function even
in the event of a fault, i.e. if there is no +54 voltage.
The glove box lighting is always powered by +30 voltage to DICE via fuse 35. The power is fed from pin 70 on the control module to the lamp (19).
Diagnosis
The output has an overload protection that shuts the output off if the load is too high. This activates DTC B1220.
DTCs are not generated if the voltage is below 11V or during diagnostic communication.
NOTE: When there is a fault in the interior lighting circuit, DTC B1220 can be generated (normally B1215) because the roof lamp (50F) is not
electrically insulated from the reading and mirror lighting.
