The most expensive maintenance problem is often the one a fleet manager didn’t know was developing.
A vehicle appears to be operating normally. Drivers continue completing routes. Nothing looks urgent.
Then a warning light appears.
Or the vehicle won’t start.
Or a relatively minor maintenance issue turns into a roadside breakdown that takes a vehicle out of service when the fleet needs it most.
Preventive maintenance is designed to reduce that uncertainty.
But managing a fleet preventive maintenance schedule becomes increasingly complicated as an operation grows. Different vehicles accumulate mileage at different rates. Engine hours vary. Service intervals aren’t identical. Drivers report problems differently, and maintenance records can become scattered across spreadsheets, paperwork and separate systems.
Telematics gives fleet managers another way to organize that process by connecting vehicle activity and diagnostic information with maintenance planning.
Why Preventive Maintenance Is a Fleet Management Issue
Maintenance is sometimes treated as a shop problem.
For fleet managers, it is much bigger than that.
When a vehicle unexpectedly goes down, the impact can spread across the operation.
A delivery may need to be reassigned. A technician might lose productive time. Another vehicle may need to cover additional work. Customers can experience delays. Managers may need to arrange rentals or other replacement transportation.
Maintenance therefore affects utilization, productivity, customer service and operating costs.
For commercial motor carriers subject to applicable federal requirements, maintenance also has a compliance dimension. FMCSA states that motor carriers must systematically inspect, repair and maintain commercial motor vehicles under their control, with vehicle parts and accessories maintained in safe and proper operating condition.
FMCSA describes “systematic” maintenance generally as a regular or scheduled program designed to keep vehicles in safe operating condition. It also notes that appropriate maintenance intervals can vary by fleet and vehicle.
That makes having a consistent process especially important.
Calendar-Based Maintenance Has Limitations
Traditional maintenance programs often rely heavily on calendar intervals.
A fleet might schedule service every few months.
That approach is easy to understand, but vehicles rarely operate identically.
One truck might travel thousands of miles during that period.
Another may spend much of its time parked.
A construction vehicle could accumulate significant engine hours without accumulating comparable road mileage.
When maintenance schedules don’t reflect actual vehicle use, fleets risk servicing some assets too early and others too late.
Telematics can help managers use actual operational information when planning maintenance.
Using Mileage to Trigger Maintenance
Mileage is one of the most common preventive maintenance triggers.
Rather than relying on drivers or managers to manually record odometer readings, connected vehicle technology can help provide updated mileage information.
A fleet can then establish service intervals based on mileage and identify vehicles approaching those thresholds.
That reduces the need for someone to continually check every odometer.
For a small fleet, manual tracking may be manageable.
For a fleet with dozens or hundreds of vehicles operating from multiple locations, automation can make a significant difference.
Engine Hours Matter Too
Mileage doesn’t tell the whole story for every fleet.
Some commercial vehicles spend substantial amounts of time running while stationary.
Construction equipment is an obvious example, but the same issue can apply to utility vehicles, service fleets and other specialized operations.
A vehicle might have relatively low mileage while still accumulating significant engine use.
Tracking engine hours gives managers another way to determine how heavily an asset is actually being used.
The appropriate maintenance schedule depends on the vehicle, equipment and manufacturer’s recommendations, but having more accurate utilization data gives managers better information for maintaining the schedule they establish.
Diagnostic Information Can Provide Earlier Warning
Preventive maintenance isn’t only about knowing when the next oil change is due.
Connected vehicles can also provide diagnostic information that helps managers identify potential issues.
Diagnostic trouble codes and other vehicle information can alert fleet teams that something requires attention.
This doesn’t replace a technician’s diagnosis.
Instead, it provides another source of information.
If a vehicle reports a potential problem while it is still operational, the fleet may have an opportunity to investigate the issue before it develops into a more serious failure.
That can make maintenance more proactive.
Connect Driver Inspections With Maintenance
Drivers are another important source of maintenance information.
They interact with vehicles every day and may notice problems before anyone else.
The challenge is making sure those observations reach the right person and result in action.
A driver might notice unusual tire wear, a warning light, braking changes or another concern.
If the information is written on paper and never reaches the maintenance team, the inspection hasn’t accomplished much.
For applicable commercial vehicles, federal maintenance rules include requirements related to inspection and correction of safety-related defects. FMCSA’s maintenance guidance emphasizes systematic inspection and keeping vehicles in safe operating condition.
Digitizing inspection and maintenance workflows can help create a clearer path from problem identified to repair completed.
Prioritize Maintenance Instead of Treating Every Alert Equally
One challenge with connected vehicles is information overload.
More data isn’t automatically better.
A fleet manager doesn’t necessarily need dozens of notifications every day. They need to know which vehicles require attention.
An effective fleet maintenance process should help distinguish between routine service, emerging issues and problems that may require immediate action.
Managers can then prioritize maintenance based on urgency and operational impact.
That makes telematics a decision-support tool rather than simply another source of notifications.
Reduce Unplanned Downtime
No maintenance program can guarantee that a vehicle will never break down.
Vehicles contain mechanical and electronic components that can fail unexpectedly.
The goal of preventive maintenance is to reduce avoidable failures.
When fleets know which vehicles are approaching scheduled maintenance, which have reported diagnostic issues and which drivers have identified defects, they can plan repairs more effectively.
Scheduled downtime is generally easier to manage operationally than an unexpected roadside failure.
Managers can arrange service around workload, shift vehicles between assignments and communicate changes before they become emergencies.
Use Maintenance Data to Make Better Replacement Decisions
Maintenance information can also help with long-term fleet planning.
Some vehicles simply become more expensive to maintain as they age.
If maintenance records show that one vehicle repeatedly requires repairs while comparable assets remain reliable, managers have useful information for replacement decisions.
The same applies when deciding which vehicles should remain in service, be reassigned or eventually be removed from the fleet.
Telematics does not make that decision automatically.
It helps provide the operational history managers need to make it more intelligently.
Build a Repeatable Fleet Preventive Maintenance Program
A strong program should make it easy to answer basic questions:
When is each vehicle due for service?
Which vehicles are approaching their thresholds?
What defects have drivers reported?
Which repairs have been completed?
Are certain vehicles generating repeated problems?
How much downtime is associated with each asset?
When managers cannot easily answer those questions, maintenance becomes reactive.
