Trailer Theft Detection (With U1D/
UET Only)
Trailer theft monitori ng can be turned ON and OFF
through the vehicle Trailer App. When enabled, any
time the trailer theft deterrent system is armed, the
trailer lighting circuits are constantly monitored to
determine if a trailer is connected for trailer theft
deterrent purposes. With the key OFF, the K68 Trailer
Lamp Control Module will randomly pulse the lighting
circuits of the trailer to verify it is still connected by
monitoring the voltage drop of the circuit. Depending on
the configuration of the trailer lights, the trailer lights
may randomly flash as part of the trailer theft deterrent
function. These flashes correspond to when the
K68 Trailer Lamp Control Module pulses the lighting
circuits to ensure the trailer is still connected and is
considered normal. If the trailer is disconnected while
the trailer theft deterrent system is armed, the vehicle
will flash the exterior lights and cycle the horn to alert of
a trailer theft event. Refer to Theft Systems Descript ion
and Operation for more information on the content theft
deterrent system.
