Semi Truck & Trailer on Highway – Mobile Diesel Repair & Heavy-Duty Transport

Big Rig Truck Repair

At OnSite Diesel Solutions, Big Rig Diagnostics start where dealership delays end. We specialize in Mobile Service for Owner-Operators, Small Fleets, and Heavy-Duty Contractors who depend on their Trucks daily.

Regen Faults, No-Starts, and Active Fault Codes tend to surface right when you're prepping for a PMI, DOT, or CARB inspection—moments where accuracy matters most. That’s why we built this section: to show how we approach Diagnostics with intent, whether it's decoding signal dropouts or chasing voltage through a harness. No speculation. No vague summaries. Just real service stories, rooted in experience and geared toward results.

Tractor & Farm Equipment Repair

OnSite Diesel Solutions provides Mobile Diagnostics and Repair for Tractors, Implements, and Farm Equipment across Yuba and Sutter Counties—no trailering required. Farm equipment doesn’t just run—it performs. Diagnostics isolate why Hydraulics lag, why Electrical Systems misfire, or why Fuel Delivery drops under load. If you're seeing stalled pivots, loss of lift, or inconsistent RPM, we bring the tools to pinpoint it. You need answers in the dirt—not guesses from behind a desk. We come to the field with dealer-level capability and get you back on schedule.

Advanced Diagnostics
Dealer-Level, On-Site

OnSite Diesel Solutions provides Advanced Diagnostics on-site across Yuba and Sutter Counties—no hauling, no waiting, no guesswork. Our diagnostic platform supports all three branches of service—Heavy Equipment, Big Rigs, and Farm Machinery—so no matter what you're running, we bring answers directly to the field. We isolate regen faults, ECU dropouts, sensor confusion, and no-starts using Jaltest multi-system diagnostics calibrated for real-world conditions. Every scan includes an official system health report, complete with fault codes, wiring references, and system status. We break it down line by line—what the codes mean, what the symptoms say, and what actions are required. If the repair can be done safely on your own, we provide self-help walkthroughs so you’re not left guessing. If it’s a fix that needs our hands, we’ve already got the roadmap built. Dealer-level testing. Field-ready precision. A solution that makes sense.
