Diagnostics
Modern vehicles generate data. The right equipment, paired with the experience to interpret it, turns that data into an accurate understanding of what is actually happening.

What This Service Covers
Diagnostics at Midway means more than reading a trouble code. Rick tests sensors, engine-management systems and control modules, tracks down intermittent faults and communication problems, and works through difficult drivability concerns that don't have an obvious answer.
That includes vehicle-network (CAN) diagnostics — CAN is how the computers in a vehicle talk to each other — so communication faults between modules can be found rather than guessed at. The testing depends on the vehicle and the complaint; there's no identical test package for every car.
Beyond the Code
Testing, not just code reading

Symptoms You May Notice
These are signs that may indicate a need for professional inspection. This is not a diagnosis — only a professional assessment can determine the actual cause.
- Check engine light or other warning indicators
- Rough running, misfiring or stalling
- Intermittent faults that come and go
- Electrical issues or module communication problems
- Reduced fuel efficiency or performance
- Difficult drivability concerns with no obvious cause
Experiencing any of these?
Tell us what your vehicle is doing. Our Diagnostic Assist helps you describe the symptoms so Rick's team is prepared before you arrive.
Tell Us What's HappeningWhy Professional Inspection Matters
A warning light tells you something is wrong — but not what. Trouble codes point to systems, not always to the specific failed component. Experienced testing beyond the code prevents misdiagnosis and unnecessary parts replacement.
What To Expect
- Professional-grade equipment used to assess your vehicle
- Sensor, engine-management and control-module testing
- Intermittent and communication faults investigated, not skipped
- An honest recommendation on what needs attention
"They can do everything from the basics to custom exhaust and structural repairs."
Come to Midway and Rick — you'll never go anywhere else.

My check engine light is on. What should I do?
A check engine light can indicate anything from a minor sensor issue to a more significant problem. We recommend bringing the vehicle in for a diagnostic assessment to determine what is actually triggering the light.
Can you diagnose the problem over the phone?
No. Accurate diagnosis requires connecting professional equipment to the vehicle. You can describe symptoms to help us prepare, but a proper assessment requires the vehicle to be present at the shop.
What is the Midway Diagnostic Assist?
Diagnostic Assist is an online intake tool that helps you describe your vehicle's symptoms before your visit. It collects useful information for our team but does not provide a mechanical diagnosis — that requires professional inspection.
Diesel & Auto Repair
Diesel engines demand a different level of expertise — and so do the drivers who rely on them. At Midway Driveline & Diesel, gas and diesel repair starts with diagnosis: finding the cause before any parts are recommended.

The driveline is what puts power to the ground. When something is off — a vibration, a noise, a hesitation — it affects everything about how the vehicle drives and works.
Learn moreBrakes & Steering
Brakes, steering and suspension are systems where guesswork isn't acceptable. When something doesn't feel right — a sound, a pedal feel, a pull, a wander — it needs to be looked at by someone who will tell you exactly what's happening.
