REAR WINDOW WIPER/WASHER SYSTEM
The tailgate window wiper/washer system is included in the scope of ZKE however is not
controlled directly by the GM. The control electronics are integrated into the rear wiper
motor assembly. It contains two hall sensors, one for monitoring park position and other
for the end stop, or to signal reverse direction of the wiper motor.
The rear wiper system is operator controlled
through the wiper stalk switch providing the
following functions:
• Intermittent rear window wiping
• Programmed rear window wiping interval
• Operation of the rear window washer
Pressing the wiper stalk forward to the first
detent activates the rear wiper in the
intermittent mode.
The default timed interval is approximately 12 seconds. The full sweep and park positions
are recognized by the two hall sensors on the motor gear assembly. If the wiper is switched
OFF, the wiper blade will return to the park position.
The programmed wiper interval procedure is identical to the E39 sport wagon; Briefly
switch the rear wiper ON/OFF, Wait the desired interval time, Switch the rear wiper ON
again. The OFF time will be the programmed interval - up to approx. 30 seconds
Rear window washing is activated by pressing the wiper stalk switch to the full forward
position. The washer pump operates followed by two full wiping cycles. The wipers will then
switch to the intermittent wiping mode.
When the transmission is shifted into reverse, the wiper will switch to continuous operation
until the vehicle is shifted out of reverse. This high signal is provided by the LCM III when it
activates the back up lights.

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.
