TECHNICAL SESSIONS
CAN Bus Troubleshooting:
We Can Fix It!
Technical Session #1
Wednesday, Sept. 28
8 - 9:30 AM
With today's commercial vehicles
becoming more complex and vertically
integrated, technicians are
finding themselves more frequently
having to diagnose, troubleshoot,
and repair vehicle networks.
The most prevalent in use today
is the Controller Area Network, or
CAN bus. CAN allows on-vehicle
Electronic Control Modules (ECM)
to " talk " to each other. It's been
around for 30 years and is now a
legislated element of automotive
(OBD-II) and commercial vehicle
diagnostics (J1939). The number of
CAN buses on vehicles are increasing
as well as the necessity to teach
technicians how to troubleshoot
and repair these networks.
During this session, we will do a
basic introduction to CAN and the
next generation of CAN called CAN
Flexible Data Rate (CAN FD). There
will be a live demonstration showing
how to use free TMC RP 1210
and SAE J2534-compliant applications
to perform initial triage of the
vehicle network. We'll also provide
a live demonstration on how to do
physical troubleshooting of a CAN
bus using a digital multimeter.
Attend this session and see how
the information provided by
the CAN bus and simple VoltOhm
measurements can make
vehicle databus diagnostics
easier and less troublesome.
EPA / CARB Emissions and
Greenhouse Gas: Changes
for 2024 and Beyond
Technical Session #2
Thursday, Sept. 29
7:45 - 9:15 AM
When it comes to emissions and
greenhouse gas (GHG) regulations,
change is the only certain
constant, and the next round
of updates to both federal and
state emissions requirements are
sure to be even more challenging
than those fleet managers
have already experienced.
Beginning in 2024, the California
Air Resources Board (CARB) and
the U.S. Environmental Protection
Agency (EPA) will no longer share
the same nitrogen oxide (NOx) regulations
for heavy-duty, diesel-powered
on-highway commercial
vehicles. This divergence will add
complexity to an already challenging
mix of regulations governing
traditionally powered vehicles.
Attend this technical session as
our expert panel will present what
changes are taking place for NOx,
particulate matter (PM), and GHG
beginning in engine model year
2024. This technical session will
also cover pertinent topics on
changes to product useful life,
emissions warranty, and clean
idle labels. We will also investigate
which states have publicly committed
to-or are intending to
follow-CARB's new regulations.
We'll also provide an overview of
what's coming in the next regulatory
transition for 2027 and beyond.
If your fleet relies on conventional
diesel-powered equipment, this is
a session you won't want to miss.
STUDY GROUP SESSIONS
How to Spec Today's Alternators
for Your Fleet's Application
S.1 Electrical Study Group
Wednesday, Sept. 28
9:45 - 11:15 AM
When it comes to electrical
power demand, today's commercial
vehicles are ravenous.
Today's alternators are expected
to supply 200-300 amps or more
of direct current to power the wide
range of electrical features that
equipment users now demand.
Is your alternator specification
keeping up with the times?
Equipment users generally agree
that many current alternator terminal
sizes, especially the 1/4 " ground
terminal, are insufficient to handle
the mechanical mounting and
connection requirements of larger
cables. There also exists strong
preference for different output
and ground terminal sizes to help
prevent miswiring to the alternator.
Attend this session as our panel
of experts delves into what
fleet managers need to know to
properly spec alternators for the
latest generation of commercial
vehicles. We'll cover how to spec
for anticipated vehicle loads,
mounting considerations, pulley
diameters and ratios, and alternator
output speeds and ratings.
The importance of industry standardization
will also be addressed.
Various TMC and other industry
recommended practices will be
covered, including those pertaining
to drive standardization,
mounting recommendations,
and terminal standardization.
Root Cause Failure Analysis for Tire
and Wheel Maintenance Issues
S.2 Tire & Wheel Study Group
Wednesday, Sept. 28
9:45 - 11:15 AM
Tires and wheels represent some
of the biggest costs a fleet has
when it comes to vehicle maintenance.
Getting a handle on tire
and wheel expenses is critical to
proper cost control for today's
commercial vehicle operations.
However, yesterday's methods
for compliant, cause, and correction
may not be sufficient
for today's operations. Relying
on parts swapping when issues
arise represents little more
than reactive maintenance.
TMC's S.2 Tire and Wheel Study
Group has produced the best
collection of condition analysis,
specification, and maintenance
information in the trucking industry.
Couple to that the latest tools
for root cause failure analysis
and you have the core elements
of a world-class tire and wheel
fleet maintenance program.
Attend this session and learn
from our panel of experts how
best to solve complaint, cause,
and correction issues when it
comes to tire and wheel maintenance
in commercial vehicle
operations. If you can only attend
one session during TMC's 2022
Fall Meeting, this one will likely
justify your week's investment.
