If you switch the ignition off
then on again and the ASC
light comes back on, there is a
fault in the ASC.
Calibration
Calibration is the process of ad-
apting control to the effective
tyre radii of the front and rear
wheels.
Effective tyre radius
Effective tyre radius depends
on tyre make, tread depth, tyre
press and the load carried on
the vehicle.
Always re-calibrate the ASC
after changing a tyre or tyres
to adapt the system to the
changed tyre radii.
As tyre wear progresses, reg-
ularly re-calibrate the ASC so
that it can operate as effect-
ively as possible.
It is not necessary to recalib-
rate the system after remov-
ing and reinstalling a wheel to
which no changes have been
made, for example when a
wheel is removed so that the
brakes can be serviced.
