The Vehicle Theft Alarm (VTA) system is an available
option on Grand Cherokee models. This system
is designed to protect against vehicle theft by monitoring
vehicle doors, hood, liftgate and ignition action
for unauthorized operation. When unauthorized operation
is detected, the VTA system responds by sounding
the horn, flashing the headlamps, park and tail
lamps and providing an engine no-run feature. Following
are general descriptions of the features of the
VTA system. Refer to Group 8W - Wiring Diagrams
for complete circuit descriptions and diagrams
