Map Light

Fault symptom

Map lighting does not work.












Conditions

The output is provided with overload protection which shuts it off in the event of an excessive load. When this occurs, a diagnostic trouble code will be generated.

DTCs are not generated if the voltage is below 11 V and the diagnostic communication is in use.

Diagnostic help

Check that the wattage of the bulbs is correct.
If bulbs of too high a wattage are fitted, DTC B1220 can be generated.
To reset the overload protection, turn the ignition key to OFF and then back to ON.

IMPORTANT: The DICE control module can be damaged if a bulb of the wrong wattage is fitted.
