Fleet Maintenance - 26

Leveraging data to
improve maintenance

VehicleServicePros.com/10095038

Even with a very basic ELD, fleets
can take the data and use it to
guide their preventive maintenance efforts.
"A concept I'm using is the 'weighted mile,'" Trimble's Orban relates.
Two drivers driving the same
make and model might behave
very differently in many ways.
"There could be different levels
of wear and tear based on driver
behavior and operating conditions," Orban says. What might
equate to one mile for Driver A
might only equate to a half-mile for
Driver B. This is a big deal when it
comes to preventive maintenance,"
Orban continues. "This gets into
what we refer to as 'prescriptive
maintenance,' which is where I
believe the industry has to go with
all of this data."
In other words, a fleet can strive
for maintenance based on what a
given vehicle actually needs - at
the proper time it needs it. The fleet
needs data to do that.
Navistar's Mulshine says a great
example of where ELD data can
help is with oil change intervals.
That is due to the relationship
between miles driven and miles
per gallon. All ELDs are required
to track mileage, and some are also
capable of pulling enough data to
calculate fuel mileage.
"When we work with fleets to
help them optimize maintenance,
we show them how to take real-time
fuel economy data to devise a plan
to extend maintenance intervals if
they can," Mulshine says. "When
you take the time to look at the
typical maintenance manual for a
Class 8 engine, you'll see that it uses
fuel economy to determine the optimum oil change interval. If a fleet
happens to have a particular driver

behind it. Predict.Health is an innovation from Trimble
Transportation that identifies vehicle performance data that is
outside a normal range to help predict fault codes. It is available
for use with Trimble's TMT Fleet Maintenance software.

who is getting lower mileage, say 5
mpg, it could be that the driver is
idling quite a bit, hauling heavy
loads the majority of the time, or
maybe working a lot of grades. In
this case, maintenance intervals
should be more frequent. But then
the fleet might have a driver who
is getting 7 or 8 mpg. This truck's
interval could be extended."
To set up the most effective
preventative maintenance plan,
Geotab's Sutarik says fleets need
not only a good ELD capable of
capturing valuable vehicle data,
but also a maintenance management system that successfully
communicates with vehicles.
"By combining maintenance
management software with vehicle
telematics data, maintenance can
be triggered automatically in the
software based on the actual utilization of the vehicle," Sutarik says.
For example, remote diagnostics programs from Geotab's
Marketplace partners - which
include Allison, Eaton, Cummins,

"When we work
with fleets to help
them optimize
maintenance, we
show them how to
take real-time fuel
economy data to
devise a plan to
extend maintenance
intervals if they can."

and Navistar - work with telematics technology to better understand the thousands of fault codes
a modern vehicle generates.
"When an engine fault occurs, for
instance, the right ELD can transmit that information, along with
GPS and other data to be analyzed
by the fleet's chosen program [software] provider," Sutarik explains.
A good example involves a
low-coolant fault code. Yes, the
coolant level could simply be low.
But there could also be a cracked
exhaust gas recirculation (EGR)
cooler, a damaged aftertreatment
system, or potential damage to the
engine. With the right ELD capturing the right data, this fault code
could be caught in time for the
driver and technician to determine
the best course of action.
That kind of "predictive" maintenance is intended to help fleets avoid
costly repairs and reduce downtime.
However, Volvo's Makki reiterates
the fact that the typical ELD will not
provide enough vehicle insights to
enable predictive maintenance.
"A fleet management solution is
needed with the ELD to maximize
data collection and use," Makki says.

Leveraging data
to improve service
scheduling
An ELD with the right capabilities
can also assist with maintenance
scheduling. Even with the most
basic ELD, data on miles and hours
is generated electronically, as
opposed to pen-and-paper which
is more prone to error.
