a significant number of questions are answered, "
Thomas said.
" If you're a fleet that is just coming up to speed
or your technicians are still ironing out details
on how they incorporate that into your fleet, that
could be a barrier, " he added. " Many dealerships
have a lot of training and are up to speed, but a
fleet may or may not be depending on how they
maintain their vehicles. "
TMC urges fleet maintenance professionals
to keep in mind that because there are several
types of ADAS technologies, they should
always be cognizant of the specific version
being serviced. That also means checking OEM
guidelines for any detailed repair, inspection,
and warranty procedures.
Proper installation, calibration
Cojali's Obispo pointed out that specific training
will ensure that service providers are well-placed
to face this new market demand. Maintenance
operations must understand the importance of
the correct functioning and calibration of the
ADAS solution, understand the different types
of calibrations, and learn the use of calibration
tools, he added.
For example, Bendix Wingman Fusion's FLC20
camera and FLR21 radar require a specific tool to
be calibrated. There are also many considerations
to alert technicians to, even if they are not specifically
addressing an ADAS maintenance issue.
" It's important to understand that the position of
windshield-mounted cameras might be disturbed
by many factors: after the windshield replacement
or installation, after vehicle body repairs that may
have affected the windshield after a control unit
replacement, after accidents, after a wheel alignment,
after a tire size change, after suspension
levels change, after the replacement of the camera
or radar, " Obispo explained. " Therefore, fleets and
service providers have the challenge to get ready
for this new technological era, and make sure that
they are able to work on the installation and calibration
of ADAS systems in order to get trucks
back on the road in optimum conditions. "
12 Fleet Maintenance | March 2022
He emphasized that if repairers are unable to
calibrate the safety systems, they should inform
customers and drivers about the necessity and
importance of getting the system calibrated somewhere
else, as well as the risks of an incorrect or
not completed calibration.
In short, Obispo added, correct calibration will
be key to guaranteeing the " perfect functioning "
of the safety system and getting the most out of
this technology. As far as fleets are concerned,
he advised maintaining a control and record of
the different systems incorporated or installed
in vehicles (type, manufacturer, model, parts, or
components that make it up).
" Based on our experience working closely with
fleet managers, service managers, and technicians,
we could say that now more than ever fleets and
repair services are beginning to realize the need for
and importance of calibration after repair work on
the part, " Obispo said. " The reason is easy; they see
that the number of commercial vehicles on the road
and in workshops that incorporate these systems
increases every day, and they want to remain
competitive in the face of this new demand. "
TEXA's Mazzon also emphasized that ADAS
calibrations, alignment processes, suspension
calibrations, and chassis/frame inspections must
be part of the long-term maintenance plan for
heavy-duty trucks.
Performing PM inspections
According to TMC, when performing PM procedures,
technicians should connect the equipment
to a diagnostic computer to check for stored, inactive,
or active fault codes, and check for any available
software updates.
Technicians should also check for any driver
vehicle inspection reports (DVIRs) that would indicate
malfunctioning, as well as visually inspect all
systems. For instance, check wiring and brackets,
and inspect for signs of tampering-that might
include high counts of inactive fault codes related
to blocked sensors or switches that are related to
safety systems like lane-departure warning.
High counts of inactive fault codes might be
related to sensors and components that drivers
unplug, such as cameras, displays, radars, and
electronic stability program (ESP) sensors to
disable ESP and collision mitigation.
Technicians should also inspect dash- or
cab-mounted camera displays, including rearview
displays, side mirror displays, blind spot displays,
or bird's-eye view displays, TMC pointed out. That
includes inspecting the surface of the display for
cracks or scratches that will impair view and test»
The ACom PRO software automatically
detects and gathers active and inactive
DTCs from all Bendix ECUs on the vehicle.
