2.5 Prerequisites
Measurement bay
• Maximum unevenness at the measurement bay:
1 mm
• Maximum unevenness at the resting surface of the
vehicle: 10 mm
• Required free space in front of the vehicle: 5–10 m
long / 4–5 m wide
 2: Free space in front of the vehicle
• The free space in front of the vehicle must not
contain metallic objects.
The SCT 815 is positioned within the free space
in front of the vehicle. Metallic objects interfere
with front radar sensor calibration.

Diagnostic software
• Diagnostic software for calibrating the front radar
sensor
• If [ESI]tronic 2.0 is used as diagnostic software: info
type SD (control unit diagnosis) and a KTS

2.6 Laser range finder GLM20
The laser range finder GLM 20 is used to position the
SCT 815 in front of the vehicle and to adjust the height
of the prismatic reflector.
The following properties of the laser range finder
GLM 20 ensure that the SCT 815 can be positioned
precisely as specified in the brief instructions specific
to the vehicle:
• Continuous distance measurement
• Rear edge as reference point for distance
measurement
For the equipment version SCT 815 (laser not
included in the scope of delivery), the GLM 20
is recommended as a laser range finder.
All properties and functions of the GLM 20 are
described in the original operating instructions
1 689 989 376. If any other laser range finder than the
GLM 20 is used, the following conditions must be met:
• Rear edge as reference point for distance
measurement

 3: Reference point for distance measurement
(1) Rear edge as reference point for distance measurement
(2) Laser exit point
• Exact length: 100 mm
• Maximum width: 46 mm
• Maximum height: 18 mm
For laser range finders with a different length,
the specifications for the distance from the
vehicle and the height of the prismatic reflector
found in the vehicle-specific brief instructions
must be converted. Laser range finders with a
different width or height will not fit into the
mount.

2.7 Functional description

A prismatic reflector must be used to calibrate the
front radar sensor of the makes Mazda, Honda, Toyota,
Kia and Hyundai. For the front radar sensor to be
calibrated, the prismatic reflector must be positioned
in front of the vehicle at a distance and height specific
to that vehicle. The adjustment device SCT 815 is used
to put the prismatic reflector in that vehicle-specific
position.
As soon as the prismatic reflector is in its vehicle-
specific position, the calibration must be started using
diagnostic software. The front radar sensor emits
signals focused and reflected back to the front radar
sensor by the reflective prism. The calibration will be
successful if the reflective prism is precisely aligned.
The calibration may fail if the reflective prism is not
