Technical Description (Comment)

WARNING: This page is about a different car, the 2012 Mitsubishi Lancer. However, it is still accessible from the selected car via links, so may be relevant.

If the activated theft-alarm siren sounds even though no faulty operation is made, the theft-alarm siren may not be able to receive the signal from the ETACS-ECU via the LIN cutoff control unit.

NOTE: The theft alarm siren may be sounding by false alarm. Investigate what kind of situation the theft-alarm siren sounded under. Check if there was any condition that caused false alarm.
