TOOL BRIEFING
each step of service procedures is truly the
only way to ensure that everything in the
vehicle is restored to proper operating conditions
after a repair. Even a simple battery
replacement requires various re-sets afterward,
other repairs are no different. Now
more than ever, reading and comprehension
skills must be honed to ensure efficient
and effective repairs.

EDUCATING OURSELVES,
CUSTOMERS, AND
OTHER SHOPS
As with all my articles, let's start with what
is possibly the most important building
block for this segment, and honestly,
most segments of the repair industry:
Education. Education is not focused
entirely on the individual tech or shopowner
being up to date but also focusing
on educating your customer base,
especially other repair facilities if you're
a shop that performs sublet work. ADAS
calibrations should be treated the same
as proper assembly and torque specifications:
You should always check to ensure
that you have the proper specifications
and procedures to ensure the vehicle is
leaving operating correctly.
There are calibrations needed with the
replacement of ADAS components and
after performing four-wheel alignments,
but there's also quite a bit of carry-over
that shops may not realize. Replacing an
air conditioning condenser on a late model
vehicle with front radar in the grille may
very well require performing calibrations
after the repair due to the removal and
p Figure 3B- ProDemand ADAS reference
re-installation of the grille. Replacing a
steering rack on some vehicles not only
requires programming the module but also
lane-keep assist or other calibrations, so
that all systems are working as intended.
So, how do we know when calibration
is needed? The overly simplified answer
is to consult your SI for proper repair procedures.
The best source for the most upto-date
information is directly from the
OEM service information system utilizing
a service subscription.
For those not familiar with accessing
the OEM side, the website oem1stop.com
(Figure 2) is a great starting point that will
get you started with using OEM websites
to their full potential.
There are various aftermarket information
systems available, such as ALLDATA
(Figure 3A and 3B), Mitchell, and
Motologic, and most have introduced
some type of quick link to access ADAS
information and charts illustrating when a
calibration should be performed, as well as
the type of calibration. These lists are not
comprehensive and should be used only as
a means of getting a basic understanding
of calibration requirements; fully reading

THE BASICS: STATIC VS.
DYNAMIC CALIBRATIONS
What are static or dynamic calibrations?
Put simply, a static calibration is a stationary
calibration that requires measurements
to be taken while the vehicle is parked. This
starts with finding the vehicle thrust line,
usually with a plumb bob (Figure 4A) and
laser. Systems like the Milwaukee Tool
three-plane laser (Figure 4B) make taking
this measurement quick and easy while
following the OEM procedures for setting
up your calibration system.
Whether you're utilizing OEM tooling
and targets or aftermarket, the calibration
stands and targets must be set up at the proper
heights and distances, as well as having
the correct back-drop (usually neutral colors
and devoid of shop equipment, lifts, and
other vehicles) to calibrate the sensors. The
calibration process is then initiated using a
capable scan tool, be it an OEM diagnostic
tool or an aftermarket tool equipped with
ADAS capable software.
A dynamic calibration can also be
referred to as driving or on-road calibration,
which allows cameras, radars, or other
sensors to properly calibrate. Just like static
calibrations, dynamic calibrations usually
require connecting a capable scan tool with
