Steering In Original Mercedes Process; Assessment Of The Data Summary Screen - Nussbaum WAB 02 CCT Instrucciones De Uso

during the steering process itself. The button for it is shown
below.
You can tell about the selection by looking at the symbol displayed
at the right bottom of the screen, if there is one. It shows either
‚20°' (TOOT), or ‚60°' (TOOT and Max Steering.
The values for both of it are measured by encoders in the
turnplates.
In the measurement sequence, you do in all cases the Micros-
weep first (caster and KPI, if selected)- then 20° right and left
(TOOT), and afterwards steering lock to lock right and left (for
maximum steering angle, if selected). It is not possible to do on
one side first 20° then maximum, and then both values of the other
side, as the measurement of maximum steering puts a lot of strain
onto the chassis, negatively influencing the values.
Recorded values for TOOT are confirmed with a big icon ‚20°',
recorded maximum steering angles by the icon ‚Max'.
Independent of the number of additionally measured values, you
can have KPI measurement selected or not, as described in 4.3.3
. In that case, you are prompted to mount the targets and brake
pedal depressor.
4.3.5

Steering in Original Mercedes Process

Please note that there are several particularities if the original
Mercedes Process is selected. One of them is that the values for
the drive-straight position are never recorded rightaway, but that
yellow triangly symbols will force you out of the center, and then
back in in a defined manner.
With the same symbols you will be hindered to measure the 20°
values for TOOT in any other way than to approach from smaller
toe values. If you overshoot, the yellow triangles will force you
back below 17,5°before yllowing you to try that point again. For
further details, please look at the description of the Mercedes
porcess.

Assessment of the Data Summary Screen

At this point, you arrive at the data summary screen, which allows
a ‚Quick Assessment'.
There, you will see the values of toe, camber etc. with straight
steering wheel, if you followed the hints given in 4.3.1. In the
center, you see toe and camber visualized in a special kind of
diagram. This one gives you a quick and good idea of the vehicle's
symmetry, even looking from a greater distance, of the car with the
steering wheel straight. When there is some major damage from
an accident, you will see it right away. Also you will be able to tell
whether there is adjustment required or not.
Looking a little closer: The yellow lines behave like slices of sheet
metal, that are fixed perfectly vertical in the center of the car
between front and rear axle. Looking from the top onto the sheet
metal, you will only see a thin yellow line. This is moreorless the
situation with toe and camber zero (left image). Toe bends the
sheet metal, you will see a curved thin line(image in center).
Camber is twisting that sheet metal. The right image shows a
combination of strong toe to the right, and camber that has the
wheel going from the left top to the right bottom. If that part of a
diagram would represent e.g. the front right wheel, there would be
strongly positive toe, and negative camber.
To both sides, the individiual values are shown, together with a
coloured evaluation: green=ok / red=not ok / gray=no specs.
Inside the field, there is also shown the range for the value being
in tolerance.
