Every repair starts with one thing: understanding the truck in front of you. That’s where the VIN Decoder inside Diesel Repair becomes a crucial part of your workflow.
With a single VIN, this tool gives you a snapshot of what you’re working with—and more importantly, it launches you directly into the tools and documents you’ll need for the job.

How to Use the VIN Decoder
- Log into Diesel Repair: https://app-repair.diesellaptops.com/#/login
- Find the section on the left side menu “VIN Decoder”
- Enter a VIN and select the search icon
- That’s it. You’ve decoded your VIN, got instant links to Fault Codes, Wiring Diagrams, and even got a comprehensive list of common parts.

What It Does
The Diesel Repair VIN Decoder does more than display vehicle specs—it connects that VIN to the tools that matter during the repair.
🛠 1. VIN to Repair Info
- Quickly access fault codes, technical documents, maintenance intervals, and wiring diagrams that are specific to the truck you’re working on.
- You go from “What am I looking at?” to “Here’s exactly how to fix it”—in just a few clicks.

🔗 2. VIN to Parts
- Get matched with parts that actually fit the unit on the floor.
- No more guessing based on general model info. VIN-to-part matching helps ensure you’re pulling accurate part data based on the truck’s build.

⚙️ 3. VIN to Smarter Workflow
- Once decoded, Diesel Repair uses the truck’s specs to filter the rest of the platform—so you only see the info that applies to that truck.
