WARNING LIGHTS

What that light on your dash means.

Check Engine Light

Could be anything from emissions issues to engine problems. Steady light means get it checked soon. Flashing light means stop driving and call us—that's serious.

ABS Light

Your anti-lock braking system detected an issue. Regular brakes still work, but ABS won't engage in an emergency. Worth getting checked.

Airbag Light

Something's wrong with your airbag system. It might not deploy in a crash. We can diagnose whether it's a sensor issue or something more serious.

TPMS Light

Tire pressure monitoring system. Check your tire pressure first—that's usually the cause. If pressure is fine, you likely have a faulty sensor. These sensors aren't very reliable and are replaced at tire shops when you get new tires.

Traction Control Light

If it's flashing, the system is actively working—that's normal. A solid light usually means you (or someone) pressed the traction control button and turned it off. Check near your shifter for a button. If you didn't turn it off, it could be a sensor issue.

Oil Pressure Light

Stop driving immediately. This means low oil pressure, which can destroy your engine in minutes. Pull over safely and call us.

OUR PROCESS

How we find the problem.

1

Listen to You

You know your car best. We'll ask about symptoms, when they started, and any patterns you've noticed.

2

Scan & Analyze

We connect professional diagnostic equipment to read codes and analyze live sensor data from your car's computer.

3

Test & Verify

Codes point us in a direction, but we confirm the actual problem with hands-on testing. We don't just guess.

4

Explain & Advise

We tell you what we found in plain English, what it takes to fix, and give you honest advice on urgency.

WHY IT MATTERS

Codes tell part of the story. Diagnosis tells the rest.

Here's what most people don't know: that code reader at the auto parts store just reads codes—it doesn't diagnose problems. A "P0420 Catalyst System Efficiency" code could mean you need a $1,500 catalytic converter... or it could mean you have a $50 oxygen sensor issue.

Proper diagnosis saves you from replacing parts that aren't actually broken. We've seen customers who replaced three or four parts based on code reader guesses before calling us. Let us find the actual problem first.

QUESTIONS

Diagnostic FAQs.

You can, and it's a good starting point. But a code only tells you what system is having an issue, not what part is actually broken. That's where diagnosis comes in. We use the code as a starting point, then test components to find the actual failed part.

Most diagnostics take 30-60 minutes. Complex electrical or intermittent issues can take longer. We'll give you an honest time estimate based on what you're experiencing.

Rare, but it happens—especially with intermittent issues that aren't acting up during the appointment. In those cases, we'll tell you what we've ruled out, what we suspect, and what the next steps would be. We won't charge for incomplete diagnostics.

Yes. The light turning off means the problem isn't currently detected, but the code is often still stored in the computer. We can read stored codes even when the light is off. It's better to catch an intermittent problem early.
