Diagnostic Function

WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.

The DTC No. B120C is stored when the voltage of the rechargeable battery is low, or when the battery inside the theft-alarm siren has an error.

NOTE: The rechargeable battery integrated in the theft-alarm siren is charged by turning the ignition switch to the ON position.
