A Peterbilt 579 that passed its pre-trip on Monday is sitting on the shoulder Thursday with a regen that won't finish and a reefer load losing temperature behind it. The defect was flagged — it just lived on a paper DVIR nobody keyed in. Peterbilt 579 maintenance software fixes that by putting every inspection, defect, PM interval and repair under the truck's VIN in one place your drivers, shop and dispatch all see. Book a demo on your 579 fleet to see it on a real unit.
Keep your Peterbilt 579 fleet ahead of every PM
Digital inspections, MX-13 and X15 preventive maintenance, defect-to-work-order tracking and an audit-ready service history — per VIN, for every 579 you run.
The 579 is a workhorse — carriers put serious miles on them, which is exactly why a slipped PM or a lost defect hurts more here than on a truck that sits. The question isn't whether your 579s need maintenance tracking; it's whether yours runs on paper or on a record that moves with the truck. Here's the difference that makes on a real shop floor.
Before / afterthe same 579 shop, run two different ways
Nothing about the truck changes between these two columns. What changes is whether the maintenance data lives on clipboards and in someone's head, or in one connected record. That's the whole gap HVI closes.
- Driver's DEF warning gets a verbal mention, never a work order
- PM intervals tracked in a whiteboard grid that's always a little out of date
- Service history scattered across invoices, folders and memory
- DOT audit means a day digging through paper per truck
- Flagged defect opens a work order automatically, tagged to the VIN
- PM fires on miles or engine hours per truck, before it's overdue
- Every repair, part and sign-off filed under the VIN
- Audit records pulled per VIN in seconds, not a day
Most carriers find the first month alone surfaces PM intervals they'd quietly let slip. Book a demo to see your 579s on one record, or explore fleet maintenance management.
MX-13 or X15engine-specific PM, tracked the way you spec'd the truck
The 579's defining choice is under the hood — a PACCAR MX-13 or a Cummins X15. They don't service on the same clock, and a single generic PM template is how an interval gets missed. HVI tracks each engine on its own schedule, so see HVI's preventive maintenance scheduling handle both in one fleet.
| Item | PACCAR MX-13 | Cummins X15 |
|---|---|---|
| Power (579 spec) | 510 hp · 1,850 lb-ft | 605 hp · 2,050 lb-ft |
| PM trigger | Miles or engine hours | Miles or engine hours |
| Oil & filters | Per PACCAR interval, flagged early | Per Cummins interval, flagged early |
| DPF / SCR / DEF | Regen & DEF checks logged | Regen & DEF checks logged |
| Fault codes | Captured to the VIN | Captured to the VIN |
Set each engine's intervals once and the due board does the counting — mileage for highway 579s, engine hours for idle-heavy or regional duty cycles. Sign up free and load your 579 PM intervals.
The checklista daily & PM check built around 579 systems
Here's the kind of 579-specific inspection your drivers run inside HVI — each line observable, with a pass / fail / defect status, no vague "looks good." Load it once as a digital form; every truck inherits it, and a failed line opens a work order on the spot.

Where hours leakwhat undisciplined 579 maintenance actually costs
Downtime on a 579 isn't one big event — it's a stack of smaller ones that a connected record would have caught earlier. Here's roughly where the preventable hours go when inspections and PM aren't joined up.
ATRI puts the average marginal cost of running a truck near $2.27 per mile — so every breakdown day on a 579 burns far more than the repair line itself in lost revenue. Book a demo to see per-VIN uptime trends.
SmartLinqtelematics data, turned into scheduled work
Peterbilt's SmartLinq remote diagnostics already pushes fault codes, DEF status and engine data off your 579s. The gap is action — a fault code nobody converts into a work order is just a notification. HVI's integration layer turns that feed into PM triggers and work orders, so the data does something.
- Fault & derate codes
- Odometer & engine hours
- DEF level & aftertreatment status
- Diagnostic health data
- PM auto-scheduled by miles/hours
- Work orders from fault codes
- Per-VIN service & repair history
- Fleet-wide uptime dashboard
Instead of reading codes in one portal and scheduling repairs in another, both live together — see HVI's telematics integration, or explore fleet analytics & reporting.
From a fleet maintenance manager
We run 579s, mostly MX-13 with a handful of X15s, and the honest truth is our PM board lived on a whiteboard that was always a week behind. A driver would call in a DEF light and it'd get written on a sticky note. Now the inspection opens the work order itself and the due board counts down per truck. We stopped missing intervals, and my last DOT audit was a non-event — I pulled every record by VIN in minutes.
Peterbilt 579 maintenance software — FAQs
Does HVI support both PACCAR MX-13 and Cummins X15 579s?
Yes. You set each engine's PM intervals and HVI tracks both in one fleet view. It also handles mixed fleets, so Freightliner, Kenworth, Volvo and trailers run in the same account alongside your 579s.
How does PM scheduling work for a 579?
PM triggers on mileage or engine hours — whichever hits first — per truck and per engine. Highway 579s usually trip on miles; idle-heavy or regional duty cycles often trip on hours first, so nothing slips.
Does it connect to SmartLinq telematics?
HVI integrates telematics feeds so odometer, engine hours and fault codes flow in automatically. Those codes can then auto-generate work orders and keep PM scheduling accurate without manual data entry.
How does it help with FMCSA compliance?
Every inspection, defect and repair is logged per VIN with timestamps and signatures, giving you a clean, pullable service history. That record supports the Vehicle Maintenance BASIC at roadside inspections and DOT audits.
Is HVI just inspections, or does it track repairs too?
Both. A reported defect opens a work order automatically, and parts, labor and sign-off are logged against the VIN. Inspection, repair and PM history live in one record instead of separate systems.
