How Engine Diagnostics and Data Collection Can Benefit Your Fleet: Q & A
Curious about engine diagnostics monitoring and data collection, but unsure how it will benefit your company? One of Mentor Engineering’s Senior Project Managers, Shubh Sidhu, sat down to talk with us about the many possibilities engine diagnostics brings to fleets. Here’s what he had to say:
Q: What is engine diagnostics exactly?
A: Basically, engine diagnostics is the ability to pull information from the vehicle’s built-in on-board computer. This real-time data lets you diagnose vehicle issues. The data collected can supplement your vehicle monitoring program or it can be standalone data. Another important piece of information that engine diagnostics delivers is engine hours, or the amount of time the engine has been running. This data is crucial for things like maintenance and repairs.
To sum it up, engine diagnostics is the interface to your vehicle’s built-in computer that gives you access to vehicle monitoring and maintenance data that you couldn’t ordinarily get.
Q: What are the benefits of engine diagnostics monitoring?
A: The ability to monitor engine diagnostics remotely saves staff time and company resources. You can collect all the engine diagnostic information, pull it out of whichever back-end software application you are using, and you now have direct access to mileage reports, or hours run, whenever you want them. This allows you to better schedule vehicle maintenance, and gives you a clear view of what vehicles are up to.
From a cost standpoint, the maintenance piece is a big advantage. By integrating engine diagnostics monitoring with your maintenance program, you can collect vehicle Diagnostic Trouble Codes (DTCs), which can greatly improve the efficiency of maintenance staff. For example, if your maintenance team knows there is a faulty component on a vehicle in advance, they can have the parts ready when that vehicle comes into the shop. Downtime is significantly reduced and the vehicle is back on the road a lot quicker. In addition, the ability to know that there’s something wrong with one of your vehicles before it becomes a major problem equalsbig savings.
There is also a safety benefit. Engine diagnostics can send certain pieces of information to show the safe or unsafe use of a vehicle, like airbag sensors, or seatbelts being fastened/unfastened. You have the necessary information to let drivers know when equipment on their vehicle isn’t properly fastened.
Q: Do you have any real-life examples to help illustrate the benefits?
A: Let’s look at American Electric Power (AEP). One of the diagnostic pieces AEP collects is Boom Up/Down status.
With engine diagnostics, they know Boom and PTO (Power Take Off) activity relative to the total mileage of their trucks. A truck might have half a million miles on it and need to be replaced, but the boom has only been used twice. They can just take the boom off the old vehicle and put it on the new vehicle. A lot of money is saved by not replacing lightly used equipment.
Q: Are there any challenges that go along with engine diagnostics monitoring?
A: Regular commercial vehicles, pickup trucks, and even paratransit vehicles all use an interface called OBDII, or On-Board Diagnostics, which makes it relatively easy to collect engine diagnostics. Heavier duty vehicles and transit buses, on the other hand, use two interfaces: J1708 and J1939. The information on the interfaces of this latter group is more detailed. There are literally hundreds of pieces of information that can be retrieved, from the hydraulic oil temperature to the oil pressure. It’s challenging because it’s harder to predict what pieces of information you can get from your fleet as it changes based on vehicle make, model and year.
Q: Without engine diagnostics monitoring, what kind of business problems might companies run into?
A: Well, they would definitely experience more vehicle downtime, their maintenance department won’t be able to use their resources as efficiently, and if they do run into situations where a vehicle breaks down because the maintenance data wasn’t available, they’ll likely see money lost in both repair costs and lost productivity.
