Power Sounder, Inclination
Sensor, and Intrusion Sensor
In addition to the standard
theft-deterrent system features, this
system may also have an inclination
sensor, an intrusion sensor, and power
sounder.
The power sounder provides an
audible alarm that is different from
the vehicle’s horn. It has its own
power source, and can sound an alarm
when the vehicle’s battery is
compromised.
The inclination sensor can set off the
alarm if it senses movement of the
vehicle, such as a change in vehicle
orientation. The intrusion sensor monitors the
vehicle interior, and can set off the
alarm if it senses an unauthorized
entry into the vehicle’s interior. Do

light will come on momentarily,
indicating that the sensor has been
disabled until the next time the alarm
system is armed.

column unlocks when the vehicle is
turned on.

column lock indicates that an issue
has been detected with the column
lock feature and the vehicle should
be serviced.

is locked indicates that the engine
is running, but the steering column
is still locked. It is normal for the
column to be locked during a
