detect both vehicle intrusions and faulty zones. For vehicles that do not have a trunk pin, or if the pin is not
monitored by the vehicle’s databus, the trunk can be hard-wired to the databus interface module.
Level I security is the default security mode setting (see the Internal Programming Jumpers section of this guide).
In Level I security mode, the standard vehicle security and operation features are monitored (see previous para-
graphs for descriptions). In addition to the standard features, there are additional features available in this
mode:
DOOR KEY DISARM FEATURE
The databus interface module can be disarmed using the driver and passenger door key cylinder, if available (not
all vehicles have a passenger door key cylinder).
SENSOR SHUNT AND TRUNK TRIGGER BYPASS WITH THE TRUNK KEY CYLINDER
Similar to sensor shunt and trunk trigger bypass with the OEM transmitter, this feature allows trunk access using
the trunk key, while the rest of the vehicle’s security system remains armed. This shunt feature will continue until
5 seconds after the vehicle’s trunk has been closed, at which point the trunk trigger and shock sensor will become
active again.
NOTE: Factory content theft deterrent (CTD) systems in Bonnevilles, Auroras and LeSabres do
not monitor the trunk key cylinder wire; therefore, the trunk key cylinder sensor bypass feature
is not available on these vehicles. The alarm will trigger if the factory trunk release feature on
the OEM transmitter is not used when accessing the trunk while the databus interface module
is armed. In Level I security mode, the H1/6 BLUE wire must be hard-wired to the vehicle’s trunk
pin wire.
VEHICLES WITHOUT CONTENT THEFT DETERRENT (CTD) AND CTD SYSTEMS THAT DO NOT MONITOR THE FACTORY
TRUNK PIN
Level I security mode is not recommended for vehicles without CTD. The databus of vehicles without CTD may not
monitor the key cylinders. Additionally, most vehicles without CTD do not have trunk pins, which would require
adding a trunk pin or hard-wiring the trunk to the databus interface module. Also, when Level I Security Mode
is used in vehicles such as Bonnevilles, Auroras and Lesabres, which have CTD systems that do not monitor the
factory trunk pin, the H1/6 BLUE wire must be hard-wired to the vehicle’s factory trunk pin wire.
Level II security can be selected by moving the Level I Security Mode/Level II Security Mode jumper (see the
Internal Programming Jumpers section of this guide) to the proper position. Level II security is a high security
setting in which the door key and trunk cylinders are not monitored by the databus interface module. The only
