General
sensor information
The following information is provided to help distributors and
glass technicians to avoid claims related to windshields with
sensors.
1.
Pre-inspection and functionality test
Prior to the removal of all windshields with sensors, functionality
needs to be proofed by spraying water onto the glass.
For combined rain
and lightsensors the lightsensor functionality needs to be proofed
by darkening the lightsensor section on the outside of the windshield.
A sensor that does
not operate correctly on the original glass will also not work
on the newly installed windshield. Sensors not operating correctly
need to be calibrated from the local OEM dealership before the
broken windshield is replaced.
2.
Sensor hints and tips
To assure correct testing of the sensor functionality make sure
that all vehicle doors are closed and the motor is running.
Example: All Mercedes
Benz vehicle sensors will only operate when all doors are closed.
This avoids that wipers splash water entering the vehicle and
keeping the driver or passenger dry.
Do not turn
the ignition on or listen to the vehicle's radio while the windshield
with sensor is removed. The electronic device will come out
of adjustment and will need to be recalibrated. This happens
because the unit receives the wrong information without the
installed windshield.
3. Glass thickness, tints, coatings and PVB interlayers on windshields
w/ sensors
Today's windshields are offered with different tints, coatings
and may have reflective or acoustic interlayers.
A windshield with
rain and/or lightsensor is developed to operate with the specific
windshield parameters. The electronic device which attached
to the optical unit processes the incoming data and reports
the information to the electronic controller which activates
the wipers and/or headlights.
By changing the originally
installed windshield (tint, coating, interlayer, thickness)
the electronic device may need to be changed as well.
Example: A Mercedes
Benz C-Class windshield in Solarextra Blue tint (FW 02473) has
a different electronic device attached than the green/grey tinted
(FW02271) glass for the same C-Class vehicle.
