noted, are designed for the specific make, model,
and year of the vehicle.
" We are noticing that the OEs are applying that
technology a bit differently from make to make, "
Thomas said. " A feature that might be called the
same feature by Bendix might operate just a little
bit differently given a different OEM. We would
encourage the fleets to get their dealership involved
to make sure they fully understand from that
specific OE point of view exactly what feature set is
on that vehicle they are ordering and to understand
how the dealership or OEM describes it as well. "
Bendix offers several troubleshooting tips to
minimize downtime for these evolving systems.
A Bendix Tech Tips series provides guidance on
troubleshooting and diagnosing advanced safety
technologies, from the foundational elements of
antilock braking to the components that enable
collision mitigation, and more.
" Sometimes the first response to an indicated
ing each type of installed camera display to check
for clarity and function.
When installed, these systems do have a test
mode. TMC urges using those instructions and
abilities to test the full function of each system.
" This is especially important to collision avoidance
and automated emergency braking systems, "
according to TMC. " It's not safe to physically test
all ADAS. "
Check for installed ADAS that include computer-guided
checks while connected to a diagnostic
computer. When they exist, TMC recommends
performing these as a routine part of preventive
maintenance.
TMC also advised that a professional driver
should test drive the equipment-only if the
systems can be tested safely. In addition, TMC
recommends inspecting the function of ADAS
technologies such as adaptive cruise, lane-change
assist, and blind-spot assist. When test driving,
see if any failures show up on the display screens.
After inspection, TMC recommends technicians
make a post PM diagnostic scan to ensure any
failure codes are cleared.
System upgrades
Historically, commercial vehicle safety systems
have typically relied on an individual radar or
camera to identify valid objects and vehicles
before issuing an alert or taking action. Supplier
Bendix has taken its latest driver assistance
system, Bendix Wingman Fusion, a step further.
Wingman Fusion integrates next-generation
advanced safety technologies like radar, camera,
and brakes into one system.
Bendix built Wingman Fusion from technologies
such as Bendix ESP (Electronic Stability
Program) full-stability system, Bendix Wingman
Advanced collision mitigation technology, and
AutoVue Lane Departure Warning System from
Bendix CVS. New features for Wingman Fusion
include stationary vehicle braking (SVB) and overspeed
alert and action.
Bendix's Thomas advised that because there
is a significant amount of engineering that goes
into these upgrades, installing ADAS technologies
is not a one-size-fits-all for fleets. Upgrades, he
electronics problem within collision mitigation
systems may be to start removing and replacing
components, " Thomas pointed out. " But there
are plenty of times when a component isn't the
issue, so we recommend starting by running a
diagnostic software tool that shows a system view
of what's on the vehicle that includes key vehicle
components as well. "
This assessment can give the technician a quick
overview of what's going on, especially when more
than one component shows similar active diagnostic
trouble codes (DTCs), such as J1939 communication
errors.
