The real problem

Repair information is scattered everywhere.

Every repair starts with the same problem: finding the right information. Technicians lose time jumping between OEM portals, old PDFs, Google searches, forums, parts catalogs, and tribal knowledge.

!
Time gets wasted before the repair startsThe search for information can take longer than the actual fix.
!
Wrong parts create expensive delaysOne bad part number can turn a same-day repair into a comeback.
!
Newer technicians need better guidanceWhen experienced techs are hard to find, your information system has to carry more weight.

The old way

  • xSearch one system for fault codes.
  • xOpen another site for wiring diagrams.
  • xCall around for part numbers and crosses.
  • xGuess at labor time or rebuild the estimate in another system.
  • xHope the information is current and accurate.

A simple repair workflow

Search it. Understand it. Fix it.

Diesel Repair is built around the way repair actually happens in the bay. Start with what you know, then move quickly to the information that helps you diagnose, repair, build the estimate, and source parts.

01

Search it

Enter a VIN, truck fault code, equipment fault code, symptom, part number, component, or equipment detail.

02

Understand it

Review truck and equipment fault-code details, likely causes, wiring diagrams, repair docs, service information, labor times, and related parts.

03

Fix it

Build a better repair plan, create the customer estimate, source the right part, and get the truck, engine, trailer, or equipment back to work.

What Diesel Repair helps you do

One platform for truck and equipment fault codes, repair, parts, wiring, labor, and estimates.

Diesel Repair is not another generic automotive lookup tool. It is built for commercial trucks, buses, RVs, trailers, engines, and off-highway equipment, with off-highway coverage across nearly every major equipment brand and model.

Off-highway is not an afterthought. Diesel Repair includes basic equipment fault-code information and a deep off-highway database across nearly every major equipment brand and model. For many customers, that off-highway coverage is harder to find than commercial truck information.
