Vehicle Diagnostics FAQs
What does a diagnostic test actually check?
A diagnostic assessment can read stored fault information, review live system data and guide targeted electrical or mechanical testing.
Does a fault code mean that part must be replaced?
Not necessarily. A code identifies a system or condition that needs investigation. The cause should be confirmed before replacing components.
Can diagnostics find intermittent faults?
Stored data, live readings, symptom history and targeted testing can help narrow intermittent faults.
Can you diagnose different vehicle makes?
RMS Bosch workshops work across a wide range of makes and models using Bosch diagnostic technology and workshop testing procedures.
