interpreting zone diagnostics
Warn Away responses are not reported by arming or disarming
diagnostics. If you receive a Bypass notification when arming or
a Tamper Alert notification when disarming, look at the in-
vehicle status LED. Active or triggered zones will be indicated by
a pattern of blinks by this LED.
Example
If Zone 3 was active or triggered, the in-vehicle LED will blink
three times with a two-second pause. Then it will blink three
times again, and repeat until the ignition is turned on.

The receiver and transmitters each use mathematical formulas
called algorithms to change their codes each time the transmitter
is used. This technology has been developed to increase the secu-
rity of the unit. The control unit knows what the next codes
should be. This helps to keep the transmitter "in sync" with the
control unit even if you use the remote control out of range of
the vehicle. However, if the transmitter has been pressed many
times out of range of the vehicle, or if the battery has been
removed, it may get out of sync with the control unit and fail to
operate the system. To re-sync the remote control simply press
note: Your system stores the last six triggered zones in
memory. If your system has been triggered but the LED
has been reset by turning on the ignition, your dealer can
still recall the last six zones that were triggered. Contact
your dealer for details.
