Tripped Sensor Identification

WARNING: This page is about a different car, the 2002 Subaru Impreza. However, it is still accessible from the selected car via links, so may be relevant.

If the horn sounds four times and the parking lights flash four times when you disarm the system, this indicates that the alarm was triggered. The number of times the indicator light flashes indicates what sensor caused the alarm condition.

Entering identification mode:

Open driver's door and leave it open.
Turn ignition switch to the ON position twice.
The indicator light will start flashing.

The indicator light provides the following indications:

Flashing one time: Any door, the rear gate, or the trunk lid has been opened.

Flashing three times: The impact sensor in the system's unit has been activated. This may indicate that your vehicle has been shocked or tampered with by some outside force and/or unauthorized person.

Flashing four times: The ignition switch has been turned on or the battery has been disconnected.

To exit this mode, close the door and turn ignition switch to the ON position.
