NOT ONLY DO TECHNOLOGICAL ADVANCEMENTS CONTINUE
with vehicles, but also with the tools used to help diagnose, troubleshoot, and repair these vehicles. The importance of having
a thorough and standardized diagnostic program with comprehensive tools is critical to quickly and accurately diagnose
vehicle issues.
The results of the 2019 Fleet Maintenance Heavy Duty Diagnostics Study are designed to provide fleets and heavy duty repair
shops with insights on the state of current product adoption, and
pain points where tools and processes may be improved.
All respondents to this survey indicated they use diagnostic
tools to work on heavy duty vehicles.
This general report provides an overview of current diagnostic tool usage, as well as current and desired scan tool functionality, among fleets.
Highlights
Below are some of the biggest takeaways from the recent study
conducted by Fleet Maintenance:
* Of the individuals surveyed, 91 percent indicate they
approve, recommend, or specify heavy duty diagnostic tools
for their fleet.
* Nearly two-thirds of respondents prefer using a software-based diagnostic platform run on a shop computer or
tablet, compared to a standalone, handheld scan tool
(36 percent).
* Respondents utilize both OE and aftermarket scan tools.
» Two-thirds of respondents use OE scan tools in some
capacity.
» Nearly half use both OE and aftermarket scan tools
* When it comes to diagnostic tool usage, respondents indicated
the top three reasons for using scan tools currently include:
» Access to troubleshooting procedures
» Checking parameter identification numbers (PIDs)
» Resetting calibration parameters on various electronic
systems
* While vehicles continue to become more advanced, some scan
tool functionalities have lagged behind, according to respondents. The top three areas where respondents would like to
see improvement in diagnostic tool functionality include:
» Troubleshooting electrical problems
» Bidirectional tests and functionality
» Coverage of OE vehicles and components
* Nearly half of respondents said having a single tool and
subscription to diagnose all vehicles serviced remains their
biggest challenge.
