Antitheft System - Alarm System Operation
SOURCE: KIA Technician Times Volume 6 Issue 6, 2003TITLE: Security System
APPLIES TO: Optima Amanti
SERVICE TIP:
When attempting to diagnose an Optima that will not set the alarm, please consider the input signals required before the system will arm itself. Typically door locks will operate normally, and you will see the hazard lights flash when unlocking with the RKE but not when locking with the RKE. Be aware that the ETACS will not arm the alarm unless all doors, hood and trunk are detected as closed. First check the door ajar input by setting the dome light to the door position and shutting all doors. If the dome light shuts off, then the door switch inputs are OK and the hood or trunk inputs are suspect. Before attempting to pin test at the ETACS, check that the rubber bumper on the hood that contacts the hood switch is in place. Without the bumper in place, the ETACS will think the hood is open and will not arm the alarm.
Note: The new Amanti has the same style hood switch.
