Modern vehicles rely on complex computer systems and sensors to keep everything running smoothly. When something starts acting up — whether it’s check engine lights, odd noises, or performance issues — the problem isn’t always obvious. At Van Wyk Auto in Sheboygan, we offer professional vehicle diagnostics that use advanced tools and experienced technicians to pinpoint the real issue quickly and accurately.
Whether you are dealing with warning lights, rough running, or unknown performance problems, our team can find the cause and help you get back on the road confidently.
What Is Vehicle Diagnostics?
Vehicle diagnostics is the process of scanning your car’s computer system and performing tests to identify the cause of a problem. Modern cars have sensors and control modules that monitor engine performance, emissions, traction systems, transmissions, and more.
When a sensor detects an issue, it often triggers a warning light on the dash. A proper diagnostic scan helps us read those codes, interpret what they mean, and find the source of the fault — so the right repair can be made the first time.
Common Symptoms That Require Diagnostics
You might need a diagnostic inspection if you notice any of the following:
-
Check Engine Light is on
-
Service or Warning Lights on the dash
-
Engine runs rough, stalls, or hesitates
-
Poor fuel economy
-
Strange noises or vibrations
-
Transmission shifting issues
-
Cooling, emission, or electrical system problems
Even if your car seems to run okay but a warning light is on, it’s worth having us check it. Ignoring warning lights can lead to bigger issues down the road.
Our Diagnostic Services
At Van Wyk Auto, we use modern diagnostic equipment and proven processes to find the right solution:
Computer Scanning and Code Reading
We scan your vehicle’s onboard computer system for codes and data that indicate what part of the system may be having trouble.
Component Testing
Once we know which system is affected, we perform hands-on tests to verify the cause and see whether parts need repair or replacement.
System Performance Checks
We evaluate related systems — like emissions, engine management, transmission, ABS, and traction control — to ensure nothing else is contributing to the issue.
Accurate Repair Recommendations
After diagnosing the problem, we explain what needs to be done, why it is necessary, and what your options are. You get clear information before we begin any repair work.

-
Getting to the root cause
-
Using data and experience, not guesswork
-
Communicating what we find in clear language

Helping you make informed decisions
Our goal is not just to fix the symptom, but to solve the underlying problem and help your vehicle run reliably.

Frequently Asked Questions
What does the check engine light mean?
It means the vehicle’s computer detected a fault in one of the monitored systems. It can be something minor or something more serious — a diagnostic scan tells us which one.
Can we diagnose without replacing parts?
Yes. We start with data and testing. If parts need replacing, we explain why and what the best solution is.
Will a diagnostic check tell me everything that’s wrong?
Diagnostics gives us the codes and data related to the fault. We use that to test further and determine the exact cause. In most cases, yes — but sometimes symptoms may involve multiple systems.
Can issues be diagnosed without warning lights?
Yes. Some problems are detected through performance testing or symptoms even when no light is illuminated.
