Is your car acting strange? Maybe the check engine light popped on, or you’re hearing odd noises that weren’t there last week.



At First Call Auto Care in Royal Oak, MI, we offer thorough car diagnostic tests that help you figure out what’s wrong before things get worse. Our professional diagnostic test is $169 and includes a detailed scan of your vehicle’s computer systems to find exactly what needs attention.


We use advanced equipment that connects right to your car’s onboard computer. This lets us read error codes and see data from all kinds of sensors throughout your vehicle.


Our certified techs don’t just read codes—they actually interpret them, drawing on years of experience to give you real answers.


We serve Royal Oak and nearby communities with diagnostic services you can count on. You’ll get a clear idea of what’s happening with your vehicle and what you should do next.

Vehicle Diagnostic Test Royal Oak, MI


Our technicians use advanced tools to spot issues with your vehicle’s systems quickly and accurately.



Check engine light on? Don’t panic. We’ll help you figure out what your car is trying to tell you with our diagnostic testing.


Our Diagnostic Process:


  • Complete computer system scan
  • Engine performance evaluation
  • Transmission system check
  • Electrical system analysis
  • Brake system testing


We use diagnostic tools similar to those from an auto parts store, but here’s the difference: you get professional interpretation, not just a printout of codes. Parts stores offer free code readings, but we dig deeper and actually analyze what’s going on.


The average diagnostic test takes about 1-2 hours, depending on your car. Our prices are competitive for Royal Oak.


Many vehicle problems give you warning signs first. If you notice weird noises, worse gas mileage, or trouble starting, it’s probably time for a car diagnostic test.


We recommend booking a test:

  1. When warning lights show up
  2. Before buying a used vehicle
  3. Every 12,000 miles as preventative maintenance
  4. If you notice your vehicle isn’t performing like it used to


Don’t wait until you’re stuck somewhere. Give us a call today. We’ll help keep your vehicle running and hopefully save you from big repair bills later.

What Does A Car Diagnostic Test Do?


A car diagnostic test means we hook up a specialized computer to your vehicle’s onboard system. This helps us spot issues in your engine, transmission, brakes, and other major parts.


When you bring your car to First Call Auto Care in Royal Oak, our tools can zero in on problems that might be making your car act up.

The scan checks different systems and pulls error codes stored in your car’s computer. These codes give us clues about what’s going on inside your vehicle.


Common Issues We Can Detect:



  • Engine performance problems
  • Transmission malfunctions
  • Fuel system irregularities
  • Emission control issues
  • Airbag system warnings
  • ABS (Anti-lock Braking System) problems


Is your check engine light on? That’s probably the most common reason people come into for a scan. It means your car’s computer noticed something it doesn’t like.


Our diagnostic equipment can tell you exactly what triggered that light. Without this kind of test, mechanics would be guessing—and who wants that?

Modern cars are packed with computer systems and sensors. These monitor everything from exhaust oxygen levels to engine temperature. When something’s off, a scan help us track down the cause.

How Often Is A Car Diagnostic Test Needed?


Regular diagnostic tests help catch problems early and keep your car running well. How often you need one kind of depends on your driving habits and how old your vehicle is.


How Long Does A Car Diagnostic Test Take?

Most car diagnostic tests at our Royal Oak facility take anywhere from 30 minutes to an hour. The actual time really depends on your vehicle's make, model, and just how tricky the issue is.


When you bring your car to First Call Auto Care, we hook up our tools to your vehicle's computer system. This lets us pull up error codes pretty fast.

If it's just a simple check engine light, expect about 30 minutes. But if things get complicated, it can take longer as we dig in and try to track down what's actually wrong.
