OPTIONAL RAIN SENSOR (AIC)
The Windshield Wiping System will also be available with an optionally equipped Rain
Sensor. The Rain Sensor provides added driver convenience and enhances safety by
automatically activating the intermittent function of the windshield wipers when water
droplets are detected on the windshield.
COMPONENTS:
The rain sensor unit is mounted on the top center area of the interior windshield surface
directly behind the rear view mirror. The unit contains:
•Optical Prism Body:This portion of the unit is
permanently fixed to the windshield. It can not be
removed and can only be replaced with a
replacement windshield.
The prism body has a reflective surface that faces
the back of the windshield. The prism body also
acts as the windshield mount for the Rain Sensor
Control Module.
•Rain Sensor Control Module:The control module incorporates the following;
- Infra Red Emitter and Detector Diodes
- Optics heater (prevents condensation from forming on diodes and prism)
- Optics evaluation and control electronics
- Photo cell to detect night time driving
The control module requires four signals for operation; KL R, KL 31, Windshield Wiper
Motor Park Signal Feedback and K Bus interface.

ANTI-THEFT (DWA) SYSTEM
The GM utilizes the following components to provide the DWA function:
• Door lock hall effect sensor contacts (door open/closed).
• Tailgate lid switch contact (monitored for closed tailgate).
• Hood switch (monitored for closed hood, located under the hood).
• DWA status LED (part of rear view mirror).
• Tilt sensor located in the electrical
carrier forward of the glove box (next
to GM)
• UIS Interior compartment monitoring
sensor (pre wiring in area of installa-
tion in center headliner).
• DWA siren (left cowl area next to mas-
ter cylinder).

DWA ARMING/DISARMING
• The DWA is armed every time the vehicle is locked from the outside with the door lock
cylinder or FZV key.
• The LED in the rear view mirror flashes as an acknowledgment along with the exterior
lights and a momentary chirp from the siren.
• The GM monitors all required input signals for closed status (door closed, tailgate
closed, etc.) The inputs must be in a closed status for a minimum of 3 seconds for the
GM to include them as an activation component. If after 3 seconds any input signal not
in the closed status is excluded (this is acknowledged by the DWA LED) preventing false
alarm activation's.
• If the DWA is armed a second time within 10 seconds, the tilt sensor and interior pro-
tection sensor are also excluded as alarm activation components. This function is use-
ful if the vehicle is transported on a train or flat bed truck to prevent false alarm activa-
tion's.
• While armed the tailgate can be opened with out the alarm being triggered as follows:
- If opened with the tailgate remote button via the FZV, the GM prevents the alarm
from activating. (This feature is customizable under the Car Memory function).
- If opened with the key at the tailgate lock cylinder the tailgate key position switch
signals the GM and in the same manner prevents the alarm from activating.
In either case, when the tailgate is returned to the closed position, it is no longer con-
sidered as an activation signal.
Panic Mode Operation: When the tailgate button is pressed and held, the GM is signaled
to activate the siren for the Panic Mode. The panic mode will function with either an armed
or disarmed DWA system.
EMERGENCY DISARMING
Emergency disarming occurs automatically if a key is used to turn the ignition switch on and
the EWS III accepts it. The EWS III signals the GM to unlock the doors and deactivate the
DWA.
