What you get
- Three defined service levels (PM-A, PM-B, PM-C) with the tasks that roll up into each
- Mileage intervals per level and a worked example of how B includes A, and C includes A and B
- Per-vehicle tracking of last and next-due PM-A/B/C
- Guidance on tiering tasks by GVWR class and duty cycle
- A printable layout for the shop board and the vehicle file
How to use it
- 1
Define what falls into PM-A (light/frequent), PM-B (intermediate), and PM-C (major/least frequent) for your fleet.
- 2
Set the mileage interval for each level from the manufacturer schedule; lighter and heavier classes use different cadences.
- 3
Remember that higher levels are cumulative — a PM-B service also performs the PM-A items, and PM-C performs A and B.
- 4
Track each vehicle's last-completed and next-due mileage for all three levels.
- 5
Sort by next-due to surface the unit closest to any service and schedule shop time accordingly.

PM Service Schedule (A/B/C) Template
Task-to-level grouping and intervals vary by OEM, vehicle class, and duty cycle — defer to the manufacturer schedule. The A/B/C split below is a common starting framework, not a fixed standard.
| Service Level | Typical Interval (mi) | Representative Tasks | Includes Lower Levels? | Unit / VIN | Last Done (mi) | Next Due (mi) |
|---|---|---|---|---|---|---|
| PM-A | 7,500 | Oil & filter, fluids top-off, lights, tires, visual inspection | — | TRK-007 | 118,400 | 125,900 |
| PM-B | 15,000 | PM-A + brake check, suspension, filters, chassis lube | Yes (A) | TRK-007 | 118,400 | 133,400 |

Frequently asked questions
Quick answers to the questions buyers usually ask once the category, software, or rollout details start getting more specific.
It is a tiered preventive-maintenance system: PM-A is the light, frequent service (oil, fluids, quick inspection), PM-B adds intermediate items (brakes, filters, lube), and PM-C is the major service (driveline, coolant, deep inspection). Higher levels include everything in the lower ones.
Intervals depend entirely on the vehicle, its class, and its duty cycle, so always defer to the manufacturer schedule. The example intervals are a common framework but should be tuned to your OEM recommendations and operating conditions.
A flat schedule lists every task against its own interval; A/B/C bundles tasks into a few standard service visits so the shop and parts room can plan around three predictable jobs instead of dozens of one-off intervals.
Yes, but set separate interval rows for each class. Light-duty, medium-duty, and heavy-duty vehicles hit each level at different mileages, so keep the task groupings consistent while varying the intervals per class.
