Diesel Diagnostics in Spokane, WA

When something isn’t right with your diesel engine, accurate diagnostics are the first step to getting it fixed properly. At ICDI Diesel Repair, we specialize in diesel diagnostics for light- and medium-duty vehicles, using advanced tools and hands-on expertise to pinpoint issues quickly and accurately.

Diesel-Specific Diagnostic Expertise

Diesel engines are more complex than gas vehicles, especially when it comes to fuel systems, turbochargers, and emissions components like DPF and SCR systems. Our ASE-certified technicians understand these systems inside and out, allowing us to diagnose problems that general repair shops may miss.

We work on Ford, Chevrolet, Dodge, RAM, and International diesel vehicles, providing precise diagnostics tailored to your specific engine and system.

Advanced Diagnostic Equipment

Modern diesel vehicles rely heavily on onboard computers and sensors. We use advanced diagnostic equipment to read fault codes, monitor system performance, and test critical components. This allows us to identify not just the symptoms, but the root cause of the issue.

From check engine lights to complex drivability concerns, we take a thorough approach to ensure nothing is overlooked.

What We Diagnose

Our diesel diagnostic services cover a wide range of systems, including:

• Check engine light and warning indicators
• Fuel system and injector performance
• Turbocharger and boost issues
• DPF and SCR emissions systems
• Glow plug and starting system problems
• Electrical and sensor-related faults
• Performance issues such as power loss or rough running

By identifying the exact cause of the problem, we help you avoid unnecessary repairs and get your vehicle back on the road faster.

Signs You Need Diesel Diagnostics

If you’re experiencing any of the following, it’s time to schedule a diagnostic inspection:

• Check engine light is on
