Factory Alarm Arm or Disarm

Since most newer vehicles come equipped with a factory alarm

system, it is necessary for the factory alarm to be

armed/disarmed when unlocking the doors and disarmed while

remote starting the vehicle.

Locate the factory alarm arm/disarm wires using the web site

vehicle information. Once the suspect wires are located, place

the multi-meter’s red lead to a (+)12 volt constant source and

secure it. Put the multi-meter in the DC position then probe the

suspect wire with the black lead of your meter. While probing

the wire, place the key in the drivers door cylinder. Turn it to the

unlock position and hold it when testing for the disarm wire.

Turn it to the lock position and hold it when testing for the arm

wire. The multi-meter should read between 10.00 volts and

13.00 volts and will disappear when the key is released.

note: Some vehicles use a + trigger system. Use the

www.diyrattler.com website to determine if your vehicle

has a + trigger system. If this vehicle has this system call

11--880000--887733--11331144

for live technical assistance as special

wiring and an additional relay is required.

warning! Do not use a test light. Use of a

test light can cause grounding of sensitive

electrical components causing damage,

including damage to the power train con-

trol module.
