Map lights not working.




Condition

The output is overload protected and is cut if the load is too high. A DTC is generated if this occurs.

DTCs are not generated if the voltage is below 11V or during diagnostic communication.

Diagnostic help

Make sure the bulb is the correct rating.

If a lamp with too high a rating is fitted, diagnostic trouble code B1220 can be generated.

The overload protection is reset by turning the ignition OFF and then ON.

Important

The DICE control module can be damaged if a bulb with incorrect rating is fitted.
