Car Feeling Off?

What is Advanced Automotive Diagnostic Testing?

Modern vehicles are equipped with complex computer networks that monitor virtually every system, from the engine and transmission to the climate control and safety features.



Beyond Basic Code Scanning

While a standard code reader can tell you what code was set, it often can't tell you why. Our professional-grade diagnostic tools access deep-level data from your vehicle's modules, providing live sensor readings, system status reports, and historical data that paint a complete picture of your vehicle's health.


The Role of the Technician as a Detective

The tool is only as good as the person using it. Our ASE-certified technicians are trained to interpret the data from our scanners. They cross-reference live data streams with technical service bulletins and their own mechanical knowledge to differentiate between a faulty sensor, a wiring issue, or a genuine mechanical failure.


A Multi-System Approach

True diagnostics isn't just for engine lights. We diagnose issues across all vehicle systems, including electrical problems, transmission shifting complaints, HVAC malfunctions, and advanced driver-assistance system (ADAS) calibrations, providing a comprehensive assessment of your vehicle's condition.

Our Process

Our Meticulous Diagnostic Process

We follow a rigorous, multi-step process to ensure we never miss the true source of your vehicle's problem. This methodical approach is what sets us apart from shops that simply "guess and replace" parts.

Step 1: Code Retrieval and Data Analysis

We begin by connecting our advanced diagnostic scanners to your vehicle's onboard computer. We retrieve all stored and pending codes, but more importantly, we analyze the live data stream from various sensors to see how the systems are performing in real-time.

Step 2: Physical Inspection and Component Testing

Codes provide clues, but physical evidence confirms them. Our technicians perform a thorough visual inspection, looking for worn components, loose connections, and signs of damage. We then perform targeted tests, such as checking voltage, resistance, and pressure on specific components related to the fault codes.

Step 3: Clear Reporting and Recommendation

We compile our findings into a detailed, easy-to-understand report. We use photos and simple explanations to show you exactly what we found, why it's a problem, and what we recommend to fix it. You get a transparent, upfront estimate before any repair work is approved.

Problems We Solve

Common Vehicle Problems We Diagnose

From a simple warning light to complex drivability issues, our diagnostic services cover a wide range of concerns for drivers in Stark County.

Check Engine Light and Emission-Related Faults

A check engine light can mean anything from a loose gas cap to a failing catalytic converter. We accurately diagnose the issue, whether it's a misfire, oxygen sensor failure, or evaporative system leak, preventing you from wasting money on parts you don't need.

Electrical Gremlins and Battery Drain Issues

If your car won't start, has flickering lights, or features like power windows are acting up, the problem is often electrical. We use ammeters and circuit testing to track down parasitic drains, bad grounds, and faulty switches.

Performance Issues: Shaking, Stalling, and Lack of Power

When your car shakes at idle, hesitates during acceleration, or stalls unexpectedly, the cause can be elusive. We diagnose these drivability concerns by testing fuel pressure, ignition components, air intake systems, and more to restore smooth performance.

Hear From Our Satisfied Customers

Don't just take our word for it. Here’s what local drivers have to say about their experience with our diagnostic services:

William McAfee shared:

“Fred and his staff have accurately diagnosed and corrected issues on my vehicles every time. Their estimates are accurate and usually less than anyone else. I am currently having them fix an issue that was created by the last mechanic I trusted. Rather than take it back to the other guy for the 4th time, I’ll have Fred fix it right... If you have issues with your vehicle, you can trust that Fred and his stall will not steer you wrong.”

Steve Stiffler noted:

"I recently went to Fix-it With Fred for a pre-purchase inspection (PPI) on a 2021 Traverse... They completed the inspection within a couple of hours and delivered a very detailed report that highlighted issues I never would have caught on my own. The insights from that report were invaluable... the PPI ultimately saved me from purchasing a potentially problematic vehicle.”

“Car(kia) had two trouble codes, poor mpg, and poor acceleration. The staff troubleshot, ordered parts, and fixed it in one day. I even got a loaner car which only cost .77cents to top off! Outstanding service!!”

Quick Answers for Drivers

Auto Diagnostics FAQ

  • How much does car diagnostic testing cost in Canton, OH?

    Our diagnostic service is priced to provide real value. The fee covers the time and expertise required to accurately pinpoint the problem. After the diagnosis, we provide a clear estimate for any repairs.

  • What does it mean when my check engine light is flashing?

    A flashing check engine light indicates a severe problem, often a misfire that can damage your catalytic converter. You should reduce power and get your vehicle to a shop as soon as possible. We offer diagnostics for these urgent issues to prevent further damage.

  • Can you tell me what’s wrong with my car just by the code?

    Not reliably. A code points to a specific system or circuit that is malfunctioning, but it doesn't identify the failed component. For example, a P0420 code (Catalyst System Efficiency) could be caused by a bad oxygen sensor, a leaking exhaust manifold, or a failed catalytic converter itself. Our testing identifies the root cause.

  • How long does a typical diagnostic session take?

    Many standard diagnostics can be completed within a day. More complex electrical or intermittent issues may take longer. We will give you a realistic timeline based on the symptoms your vehicle is exhibiting.

  • Do you offer diagnostics for all vehicle makes and models?

    Yes, our team and tools are equipped to handle a wide range of domestic and Asian vehicles, from Chevrolet and Ford to Honda, Toyota, and Jeep. We service gasoline, hybrid, and electric vehicles that are 20 years old or newer.

  • What’s the difference between your diagnostics and a free code scan at a parts store?

    A parts store scan simply reads the code. Our diagnostics involve using professional tools to read codes, analyze live data, perform active tests, and physically inspect components to find the root cause of the code, which is essential for a correct and cost-effective repair.

  • My car has a problem but there’s no warning light. Can you still diagnose it?

    Absolutely. Many issues, such as noises, vibrations, or performance problems, may not trigger a fault code. Our technicians are skilled in diagnosing these types of concerns through a combination of road testing, mechanical inspection, and data analysis.

  • What does your 24-month/24,000-mile warranty cover?

    Our warranty covers both parts and labor on most repairs we perform, giving you confidence that your investment is protected long after you leave our shop in Canton.
