TMC Special Section
VMRS UPDATE
VMRS adapts
to standardize
predictive and
prognostic
maintenance alerts
BUILDING ON CODES FOR CRASH AVOIDANCE AND
LANE DEPARTURE, TMC FOCUSES ON A NEW CLASS OF
CODING TO COMMUNICATE ANTICIPATED SERVICES.
By Jack Poster
CBM
From its inception, the Vehicle Maintenance
Reporting Standards (VMRS) have been a
collaborative effort involving a diverse group of
contributors representing the equipment maintenance
industry. Original equipment manufacturers
(OEMs), parts manufacturers, fleets, service
providers, and fleet maintenance software firms
have all played a part in helping to expand the
scope and acceptance of VMRS. It's been a team
effort for more than 50 years and continues to be
going strong year after year.
In recent years, ATAs' Technology & Maintenance
Council (TMC)-the custodian of VMRS-
have added codes for crash avoidance, lane
departure, camera monitoring systems, adaptive
speed control, and most recently, electric vehicles,
all with the help of folks from the VMRS-user
community. VMRS continues to reflect new technologies
that are developed for equipment and
equipment maintenance and will continue to do
so for many years.
The torrent of activity surrounding telematics
services has prompted TMC to begin considering
a new class of VMRS coding to address predictive
and prognostic maintenance alerts. These codes
will standardize the electronic maintenance alerts
back office systems communicate to vehicles when
services are anticipated.
Brian Mulshine, director of digital service delivery
at Navistar, started the conversation during
the VMRS Codes Task Force meeting at the 2022
TMC Fall Meeting. The idea is to create a common
language/schema in VMRS to be leveraged by vehicle
OEMs, engine manufacturers, and component
suppliers to digitally communicate " predictive/
prognostic maintenance alerts/requirements. "
VMRS coding has traditionally been used to
record maintenance/repair data after the service
event takes place. Parts and labor are usually
entered by the attending technician or manager,
using some type of maintenance software or filling
out a work order by hand.
However, with the advent of artificial intelligence
(AI) and machine learning, things in the
maintenance world are changing. Vehicles, equipment,
and/or components now send diagnostic
information directly to the maintenance depart30

ment. There needs to be an agreed upon method
of interpreting and implementing the received
data, and many believe VMRS is the perfect method.
It's been the " universal " maintenance language
for more than 50 years and continues to prove to
be flexible and adaptable.
VMRS Code Keys are data elements or data
" buckets " that hold individual codes of just about
anything pertaining to maintenance, repair, and
vehicle specification. Think of a Code Key as an
individual book in the VMRS library. There's a
book for repair reasons, work accomplished, part
position, part identification, etc. Most industry
professionals are familiar with the VMRS nine-digit
Component Code Key 33, but VMRS comprises 65
separate Code Keys, each containing codes related
to various areas of equipment maintenance and
equipment designation. There are Code Keys that
contain codes for designating labor, part failures,
equipment attributes, and much more.
As technology evolves for improving maintenance
of vehicles, most OEMs are working
on " data driven " maintenance to improve the
customer's experience. New forms of maintenance
include condition-based maintenance
(CBM), sensor-driven and dynamic (advanced)
PMs, and methods of leveraging real-time fuel
economy to adjust intervals.
Mulshine has brought
in many interested
parties from various areas of equipment maintenance
to help develop this new standard - OEMs,
fleet software providers, engine manufacturers,
and fleets have all expressed an interest in adding
the new Code Key to VMRS. They all agree on the
need for a common language for indicating the
required needed service. The codes can be used
across all vehicle/engine OEMs and component
suppliers to digitally communicate predictive and
prognostic maintenance and repair requirements.
Multiple vehicle and engine manufacturers
have data currently or becoming available soon
that designates remaining useful life (RUL) of
certain components and/or maintenance due
soon. Because no standard is currently available,
fleets are receiving this information by email
with attachments. Customers are then expected
to take the data and enter it in their systems.
Sensordriven
Dynamic
The
proposed VMRS Code Key will include new
codes with this information, offering fleets a way
to communicate and receive this important data.
The new VMRS Code Key is expected to include
service requirements that are due soon, past due,
and need replacement soon. Some examples are:
* Past due - Oil change, fuel filter, lube driveline.
* Due soon - Valve lash adjustment, DEF filter.
* Needs replacement soon - Air dryer, fan belt.
Mulshine has put together a list of service
requirements from several OEMs that will be the
basis for the code descriptions in the new Code
Key and, like the existing VMRS Code Keys, there
is always room for expansion.
Another proposal is to expand existing VMRS
Code Key 52: Part Status Codes to include required
elements for predictive and repair dispositions. The
code key would be renamed " Maintenance and Part
Status " reflecting the new proposed VMRS Code
Key. Examples include " due soon, " " past due, "
" service immediately, " and " request performed. "
New VMRS Code Key proposals are subject
to the same balloting and appeal development
process as any other TMC Recommended Practice.
They must be first developed and approved
by the VMRS Codes Task Force, then reviewed by
the appropriate Study Group Chairman and TMC
staff, then put up for balloting to the entire TMC
membership. If balloting is successful, and there
are no appeals following the balloting approval, the
Code Key will become part of the VMRS library,
collectively entitled TMC RP 802, TMC/ATA Vehicle
Maintenance Reporting Standards (VMRS).
The Task Force is working on the proposed additions
this summer and expects to send the new
material for balloting following TMC's 2023 Fall
Meeting in Cleveland, Sept. 17-21.
VMRS has always reflected the latest in technology
when it comes to maintaining many types
of equipment, it's been the industry standard for
more than 50 years and will continue its mission
into the future. The industry is undergoing rapid
change and VMRS promises to keep current and
relevant to its many users no matter what the
future brings.
