Diagnostic Services FAQs
What does a diagnostic scan include?
We read active & pending trouble codes, test live sensor data, and perform manual circuit testing to pinpoint root causes.
What does a diagnostic visit cost, and does it go toward the repair?
The diagnostic fee depends on how much testing the problem needs, and we will tell you the expected charge before we start. If you approve a repair at our shop, we can discuss how the diagnostic time applies to that job.
Can you read the check engine light without a shop visit?
A code reader can show a trouble code, but the code only points to a symptom, not always the cause. We read the codes, look at live sensor data, and test the circuit before we recommend a part.
