Maximum Turn Angle (Lock to
Lock)
This routine is very similar to the Toe-Out-On-Turns
feature. It allows the measurement of the “full lock” or
maximum turn in each direction. Consult an alignment
specification manual or shop service manual for
manufacturers specifications for the maximum turn
reference angle and the outside turn value.
1. After completing the caster/SAI and toe-out-on-
turns measurements on one side, continue to turn
the wheel past 20
o
. The software senses this and
places a red status bar over the maximum turns
icon.
2. Continue turning the wheel as far as it will go to the
full lock position on this side. Hold steady until the
green box/depressed icon appears and the stop
sign disappears, indicating the measurement is
completed.
3. To measure maximum turn angle on the other side,
begin to turn the wheel the opposite direction. Note
that the status bar appears over the caster/SAI
icon first. It is always required to measure caster/
SAI, then toe-out-on-turns before maximum turn
angle.
4. Perform caster steps and toe-out-on-turns steps,
then continue turning out to measure at full steering
lock.
5. Hold steady until the green box / depressed
icon appears indicating the maximum turn angle
measurement is completed.
6. The software then places a red bar over the center
steering icon. Follow the arrow to the center until
the stop sign appears.
When the desired steering measurements are
completed, the software prompts the operator to center
and lock the steering wheel before performing any
alignment adjustments. After a few seconds the
Aligner
automatically advances to the alignment readings
screens if “Screen Timeouts” has been enabled.
