Truck data is a valuable asset for fleets looking to improve maintenance and operational decision-making. In this Tech Tip, we explore the risks of losing data when replacing truck components and what steps a technician should take to ensure data is saved and transferred during the process.
Heavy-duty trucks rely on various communication protocols to transmit data, such as diagnostic information and vehicle data. In the 1990s and early 2000s, J1708 was the common protocol and required a 6-pin cable to connect to the truck’s diagnostic port.
Gone are the days of only having one diagnostic port to connect to in the cab. Many modern trucks are equipped with two ports, with only one providing all the relevant diagnostic data. This Tech Tip explains how to choose the correct port for improved diagnostics.
As adaptive cruise control technology became prevalent, we began noticing a major increase in adaptive cruise faults that were stumping technicians and leading to unnecessary vehicle downtime. Fortunately, many of these faults are simple to fix.
Too often, technicians are forcing a DPF regen when it is not the correct procedure. Doing so causes extra downtime, decreased lifespans of truck components, and wasted fuel. View our tips on how to decide if the regen is the correct procedure based on the truck’s current state.
Don’t just assume a DPF regen it’s the correct procedure when fault codes mention the aftertreatment section. Learn how to identify when a regen is necessary to help reduce costs and improve the lifespan of the truck.
Nearly 13.5% of commercial motor vehicles inspected during the 2019 Brake Safety Week were placed out of service. Don’t become part of this statistic in the future, learn how to improve the health and safety of your trucks by improving your visual inspection process.
Keeping your mental toolbox stocked is just as important as the physical tools in your real toolbox. Using free educational resources, technicians can stay updated on the latest procedures and technology.
A crucial part of a technician’s job is to verify the complaint of the customer in order to make an accurate diagnosis and repair the root cause of the issue. Using Freeze Frame data can help technicians determine the root cause of truck issues.
Not all faults are created equal; not only do they vary in severity levels, but certain faults also take diagnostic precedence while others should be ignored completely. Learn how to identify transient faults and why you should ignore them to make the correct diagnosis.
Using JPRO’s wiggle test, technicians can monitor changes in fault status or data that moves above or below a threshold while wiggling connectors or wires on a running vehicle.
A proper PM procedure allows technicians to discover all issues on the vehicle and helps fleets reduce unexpected downtime. Learn how to improve your Preventative Maintenance process using detailed, configurable checklists.
