FAQs
Q1: What’s the difference between diagnostics and a code scan?
A basic code scan pulls a trouble code, but diagnostics involve real testing and data analysis to find the root cause of the issue.
Q2: Can computer diagnostics detect electrical problems?
Yes. We use scan tools and voltage testing to identify shorts, sensor failures, and other issues that don’t always trigger a check engine light.
Q3: Will you explain what the codes mean?
Absolutely. We walk you through what the codes indicate, what’s causing them, and what your repair options are, without any upsell pressure.
Q4: How long does a full diagnostic take?
Most diagnostic tests take 30–60 minutes depending on the issue. We will give you an update before recommending any next steps.
