Good reasons to request a diagnostic
A diagnostic makes sense when the check engine or another warning light is on, when the car is running differently than it should, or when a specific system isn't working as expected. It's also useful before a long trip if you want peace of mind about a known concern.
What a diagnostic includes
A diagnostic typically involves reading the stored trouble codes, inspecting the related system, and testing the suspected components. The goal is to connect the code or symptom to a verified cause — not to list every possible part that could be wrong.
What a diagnostic doesn't do
A diagnostic doesn't guarantee a fix on the spot, and it doesn't replace the need to inspect and test before replacing parts. We explain what we find and let you decide what to repair.
