  • Why Manufacturer-Specific Certifications Matter

In the competitive world of diesel technology, getting specialized training can help you stand out from the crowd. Additionally, earning manufacturer-specific diesel certifications is a powerful way to showcase your skills, proving to employers that you have the brand-specific knowledge needed to work on their engines.1

Keep reading to learn about how these diesel mechanic certifications can help you in your pursuit of a diesel technician career and how you can take steps toward earning them.

What Are Manufacturer-Specific Certifications?

Earning manufacturer-specific certifications shows that a diesel technician is trained and skilled to work on specific brands of vehicles. The training needed to achieve these certifications provides in-depth knowledge of a specific brand’s diesel engines, diagnostics and repair procedures, helping set certified technicians apart from general diesel mechanics.

Why Manufacturer-Specific Certifications Matter

Manufacturer-specific recognitions

Aspiring diesel technicians may be able to earn specific recognitions depending on the program they’re in. For example, those enrolled in the Daimler Trucks North America (DTNA) Finish First program earn six certifications and Professional Level Technician status, and students who take the Cummins Engines program are classified as CMI Level 1 Technicians.

More competitive skill set

Many dealerships and fleet service centers prefer or require technicians to have some level of original equipment manufacturer (OEM) training. Holding these certifications may help make technicians more competitive in the job market, especially compared to techs without this specialized knowledge.6

Experience with brand-specific tools, technology and training

Diesel technicians with manufacturer-specific certifications typically have more experience using specialized  diagnostic tools and software and know how to perform more advanced repair procedures. This specialized knowledge allows them to efficiently diagnose and repair a manufacturer’s diesel systems, improving service quality and efficiency.

Popular Manufacturer-Specific Programs for Diesel Technicians

There are several programs that can help aspiring diesel technicians gain training with a specific brand, and some schools offer specialized training where students get the chance to earn manufacturer-specific certification.
