twice within 0.5 seconds in 2 second cycles after 30

seconds.

6) Hit all windows with the palm with force repeat-

edly, to check for whether the security alarm oper-

ates. Lift up the front hood approx. 12 cm (4.7 in) or

more, and then drop it off to check the operation of

security alarm.

2. IMPACT SENSITIVITY ADJUSTMENT

1) Connect the Subaru Select Monitor to the data

link connector.

2) Turn the ignition switch to ON.

3) On the “System Selection Menu”, select {Impact

Sensor}.

4) Make a {Sensitivity Adjustment Mode}.

• Sensitivity can be adjusted in 11 levels (0 to 10).

• Initial setting is 5.

• Smaller number means more sensitive.

• Larger number means less sensitive.

5) Turn the ignition switch to OFF, and then remove

the Subaru Select Monitor.
NOTE:

• Set the sensor so as not to let the alarm on nor-

mal vibration (reclining to the door, hit the ball and

etc.).

• Set the sensor to operate the alarm with hitting

the door or window glass, etc. continuously like a

mayhem by robbery.

• Even if there is no burglary attempt, if there is vi-

bration (road construction, elevated parking lots,

passage of trains or boarding of ferries), the alarm

can be triggered. Because of this, ask the customer

about their parking conditions, and set an appropri-

ate sensitivity level after discussion.

• The impact sensitivity can also be adjusted on

the manufacturer’s optional display, and it can be

set in 11 levels from 0 to 10. The sensitivity is set to

5 by default. (Unlike the specification of the Subaru

Select Monitor, the setting becomes duller as the

setting value becomes smaller, and more sensitive

as the number becomes larger.)

• If the sensitivity setting was not performed prop-

erly, a buzzer will sound four times. In this case,

check the following:

• Is there an error in CAN communication?

• Is there an open circuit in the harness between

the body integrated unit and the impact sensor?

• Is there a malfunction in the display, body inte-

grated unit or impact sensor?
