Independent service for Hino trucks operated by owner-operators and commercial fleets. Warning light, failed regen, losing power, or due for an annual safety inspection — we diagnose it properly before any parts get replaced.
If any of this sounds familiar, it's worth a proper diagnostic before parts start getting replaced.
We assess warning lights, starting problems, charging-system concerns, electrical faults, abnormal operating symptoms, and related trouble codes. See our heavy-duty engine diagnostics page for how the process works.
We investigate emissions warnings, unsuccessful regens, reduced-power conditions, and aftertreatment faults. A trouble code identifies the affected system; it does not always identify the failed part. Proper testing is required before repair decisions are made. Background reading: our DPF & DEF Diagnostic Guide.
Mr Diesel provides commercial vehicle inspections through Ontario's DriveON program. If defects are identified, we explain the findings and request your authorization before completing any repairs. See our Annual Safety Inspection page for the full 90-point process.
We service safety-critical brake, air-system, suspension, and steering concerns on commercial Hino trucks. More detail on our heavy-duty brake service page.
Routine inspections and maintenance can uncover developing problems before they cause unscheduled downtime. Ask about maintenance support for individual trucks and small fleets — see our Fleet PM Programs.
Diagnostic and repair capability depends on the vehicle year, engine, system, and required tooling. We confirm service suitability after reviewing the VIN and complaint.
We start with your description of the problem, the VIN, and any fault codes already showing.
Live data and proper testing — a trouble code tells us the system, not always the failed part.
We walk you through what we found in plain language before recommending anything.
An itemized repair plan, so you can make an informed decision before expensive parts are replaced.
Work proceeds only once you've signed off, and is verified before the truck goes back on the road.
Warranty repairs, safety recalls, manufacturer campaigns, and certain programming functions may require an authorized Hino dealer. We will tell customers when a concern falls outside our capabilities instead of promising work we cannot properly complete.
