Diagnostic Service FAQ

Common questions about car diagnostics and troubleshooting

What does the check engine light mean?

The check engine light indicates that your vehicle's computer has detected a problem with the engine, transmission, or emissions system. It could be something as simple as a loose gas cap or as serious as a major engine problem. Our diagnostic scan will identify the exact cause.

How much does a car diagnostic cost?

Our basic diagnostic scan starts at $99 and includes a complete OBD-II system scan with code analysis. More comprehensive diagnostics start at $149 and include advanced testing of multiple vehicle systems. Prices may vary based on your vehicle and the complexity of the issue.

How long does a diagnostic take?

Most basic diagnostics take 30-60 minutes. More comprehensive diagnostics may take 1-2 hours depending on the complexity of the issue and how many systems need to be tested. We'll give you a time estimate when you arrive.

Can I drive with the check engine light on?

It depends on the severity of the problem. Some issues are minor and won't affect drivability, while others could cause serious damage if not addressed. We recommend getting it diagnosed as soon as possible to prevent further damage or safety issues.

What's the difference between OBD-I and OBD-II diagnostics?

OBD-II is the current standard used on vehicles from 1996 and newer. It provides more detailed diagnostic information than the older OBD-I system. Our equipment can work with both systems, but OBD-II provides much more comprehensive diagnostic capabilities.
