14.2 - Alignment problems
The steering wheel remains askew
Runout compensation not exe-
cuted
Repeat the measurement executing runout compensa- •
tion
If you do not intend to execute runout compensation,
•
minimise the runout error by using 3-point wheel
clamps or grippers designed to minimise the runout
error of 4-point wheel clamps
Runout compensation executed
inaccurately Repeat the measurement and during runout pay attention
to:
Follow the instructions which may appear on the •
screen
In the case of runout on the ground, fi t the steering
•
lock
Turn the wheels with a small tolerance with respect to
•
the required angles; especially for the 90° runout
Release the turn plates and the rear slip plates and
•
settle the suspension after lowering the vehicle in case
of runout with the vehicle lifted
Alignment executed in the mode
with 2 measuring heads Repeat the measurement in the mode with 4 measuring
heads
Steering wheel not aligned when
requested Repeat the measurement aligning the steering wheel
when requested
Approximate adjustment of the
alignment angles Repeat the measurement adjusting the angles more accu-
rately
Excessive play in the suspension Replace the mechanical parts with play
Toe-in or camber not plausible
Runout compensation not exe-
cuted Repeat the measurement executing runout compensation
Greatly different tyre pressures Equalize the tyre pressures
Toe-in not plausible
Only for side-by-side car lifts
CCD sensor disturbed by the LED
of the measuring head on the
adjacent car lift
Place a panel between the car lifts
CCD sensor disturbed by a re-
fl ection on the refl ecting surface Identify and darken the refl ecting surfaces
