Anti-Theft Alarm (DWA)

The DWA anti-theft system is a dealer
installed accessory option. All E46
vehicles are factory prepared to provide
the DWA function. This means that the
vehicle is prewired and the General
Module (GM V) is preprogrammed for
the system. However, once the DWA
system components are installed the
GM V must be coded, using the DIS or
MoDiC, to recognize the installed
components and carry out DWA
functions.
The GM V utilizes existing components
and/or circuits as part of the DWA
system:
Door lock hall effect sensor
contacts
Trunk lid switch contact
Trunk lock key position switch
Hood switch
DWA status (LED)
The DWA accessory kit includes the
following:
Tilt sensor in right trunk area
UIS (interior monitoring sensor) in
center of headliner
Siren in cowl area next to IHKA
housing
