What We Handle On-Site
Hino medium-duty problems we diagnose and repair
DPF & aftertreatment
Clogged DPFs, failed and incomplete regens, DEF and SCR faults, and the aftertreatment warning lights that shut down short-cycle delivery trucks.
Injectors & fuel
Rough running, hard start, low power, and misfire complaints on J05 and J08 engines traced to injector performance and fuel delivery.
Sensors & check-engine
NOx, temperature, and pressure sensor faults, EGR codes, and check-engine conditions read and tested before parts get replaced.
Box-truck uptime issues
Batteries, charging, no-start, and the stop-and-go wear items that take delivery and box trucks off the route.
Why Call a Mobile Hino Tech
Keep the delivery truck on the route
A Hino box truck sitting at a dealer is a missed route and lost revenue. Medium-duty delivery trucks that run short cycles all day are especially prone to DPF and regen trouble — and most of it can be diagnosed where the truck is parked instead of after a tow and a wait.
Lowcountry Diagnostics brings the diagnostic equipment to your yard or distribution center and works the fault systematically. You get a clear answer: what failed, what was tested, and whether the Hino can be fixed on-site to get the driver moving again.
Why operators call us
- Mobile service where the truck is sitting
- Testing before parts replacement
- Clear written findings and next steps
- Commercial diesel and fleet-focused support
- 24/7 Charleston-area availability
How We Work
What happens when you call
1. Tell us the truck and the symptom
Hino model (155–338), engine (J05 or J08), warning lights, and what it is doing point us to the right first tests.
2. We come to the Hino
Yard, distribution center, terminal, or route stop across the Charleston area — no tow required to get started.
3. Read codes and live data
Regen status, aftertreatment temps, DEF dosing, injector and sensor data confirm the actual fault instead of guessing.
4. Repair or direct
When an on-site fix is practical — sensor, regen, injector, or wiring — we handle it. When it is not, you get a clear next step.
5. Plain-language findings
You know what was checked, what failed, the likely cause, and the recommended next step for the truck.
6. Keep the fleet moving
Repeat and fleet Hino customers get priority scheduling and preventive checks to head off the next DPF or regen shutdown.

Common Hino repair questions
Do you work on Hino J05 and J08 engines?
Yes. We diagnose and repair Hino medium-duty trucks with J05 and J08 engines across the 155, 195, 258, 268, and 338 models, including DPF and aftertreatment faults, injector problems, and sensor codes.
Can you fix a Hino DPF or regen problem on-site?
Usually. Hino box trucks that run short delivery cycles are prone to incomplete regens and clogged DPFs. We diagnose why regen is failing, test the aftertreatment sensors and dosing, and address the real cause instead of just forcing a regen.
Do you handle Hino injector and hard-start issues?
Yes. We test fuel delivery, injector performance, and the electrical side of rough-running, hard-start, and low-power complaints on Hino medium-duty trucks where they sit.
Do you come to my location for a Hino box truck?
Yes. We are mobile and come to your yard, terminal, distribution center, or route stop throughout the Charleston area to keep delivery trucks moving. Call or text (843) 310-0995.
