product description
This unit is used to enhance a vehicle’s original equipment from manufacturer (OEM) factory keyless entry system
by converting it into a full-featured alarm system. It has been designed to work with the factory transmitters
and to interface with minimal wiring to the vehicle. The databus interface module interfaces with the vehicle’s
Class II databus signal wire to arm and disarm the vehicle, and to determine if there has been a vehicle intru-
sion.
Vehicles with the Class II databus, which can be interfaced with databus interface module are:
■
2000 and newer Cadillac DeVille and Seville
■
2000 and newer Buick LeSabre
■
2001 and newer Oldsmobile Aurora
■
2000 and newer Pontiac Bonneville
■
1999 and newer Jeep Grand Cherokee
installation points to remember
BEFORE BEGINNING THE INSTALLATION
■
Check with the customer to decide on a status LED location.
■
Use seat and fender covers to protect the vehicle.
■
Remove the domelight fuse. This prevents accidentally draining the battery.
■
Roll down a window to avoid being locked out of the car.
■
Do not disconnect the battery if the vehicle has an anti-theft coded radio. If equipped with an airbag, avoid
disconnecting the battery if possible.
■
Remove necessary under-dash trim panels to provide access for mounting the system’s components.
IMPORTANT!
Please read this entire installation guide before beginning the installation. The instal-
lation of this security system requires interfacing with many of the vehicle’s systems. Many new
vehicles use low-voltage or multiplexed systems which can be damaged by low resistance testing
devices, such as test lights or logic probes. Test all circuits with a high-quality digital multi-meter
before making the connections.
IMPORTANT!
Many airbag systems will display a diagnostic code through their warning light after
they lose power. Disconnecting the battery requires this code to be erased, which can require a trip
to the dealer.
