Steering rack centering 4.2
The steering rack is electric and steering angle sensor has to be electronically aligned with the wheels on
the main time.
How to proceed align the steering angle sensor:
It is necessary fix the steering wheel. To do it, you can use straps fixed on the top of the roll cage or
other kind of std. tools. The most useful is two straps going through the steering wheel and the roll cage.
The use of a rack centring stopper tool is not recommended because is difficult to get the steering angle
sensor at “0 deg”. The most important is to obtain the toe alignment with the sensor at “0 deg”.
Proceed as following:

Switch on main and ignition switches.

Turn left and right to get the steer angle signal.

Fix the steering wheel with straps when the steer angle
is “0 deg”

Switch off the ignition and main.

You can now preceed to the alignment jobs.
With this process the steering angle signal will be at 0 deg, with the wheels aligned. This fact is
very important for the steering assistance and for the electronic slip differential behaviour.
