Type B Switch Test
Use the meter or test light to find
a point on the fuse block that pro-
vides a constant source of +12
volts. Touch one lead to that point
on the fuse block, and the other
lead to one of the control wires.
Operate your power door locks.
If the light turns on or the volt
meter indicates 12 volts when
you move the door lock switch to
the LOCK position, you have
located a Type B
Lock
control
wire. Test the other wire.
If the light turns on or the volt
meter indicates 12 volts when
you move the door lock switch to
the UNLOCK position, you have
located a Type B
Unlock
control
wire. Test the other wire (if you
have not already done so).
If both wires are Type B control
wires, go to Step 3.

DETERMINING YOUR
VEHICLE’S DOOR
SWITCH POWER TYPE
For your alarm system’s passive arm-
ing and anti-carjacking features to
work, you must connect the alarm to
the door switch power lead. Follow
these steps to determine the door
switch power type.
1. Use your vehicle’s service man-
ual, contact your vehicle manu-
facturer, or contact the Auto
Alarm Helpline at 1-800-598-
2527 to determine where to
access the control wire(s) for
your vehicle’s door switch. This
wire might also be called a door
trigger and is usually behind a
panel near or on the door.
Notes:
• Some vehicles have logic-
controlled dome and courtesy
lights that turn on differently
depending on which vehicle
door is opened. Be sure to
locate a wire that is triggered
from all your vehicle’s doors.
• If your dome light dims slowly
when you close the door, your
alarm might have problems
determining when the door is
opened or closed. Contact 1-
800-598-2527 if this is the case
with your vehicle.
