FAQs
How do I know if my vehicle needs a diagnostic service?
Signs that your vehicle may need diagnostics include warning lights on the dashboard, poor engine performance, unusual noises, stalling, or difficulty starting.
Will I always need to replace parts after a diagnostic test?
Not necessarily. Sometimes diagnostics reveal simple issues that can be repaired without part replacement. In other cases, a part may need to be replaced to restore proper function.
What types of problems can engine and electrical diagnostics detect?
Diagnostics can identify a range of issues including faulty spark plugs, bad sensors, engine misfires, wiring problems, battery issues, and more.
Can a diagnostic test detect all car problems?
While diagnostic tests can identify many issues, some problems may not trigger a code or be detected through the standard diagnostic process, like certain mechanical failures.
Can diagnostics fix the problem, or is it just for identifying issues?
Diagnostics are used to identify issues. After the problem is pinpointed, the necessary repairs or replacements can be made to fix the issue.
What happens if my diagnostic test reveals a problem?
If a problem is found, we’ll explain the issue and provide an estimate for repairs or replacements needed to resolve the problem.
