Modern vehicles can store fault information long before the cause is obvious. Diagnostics helps narrow down the system that needs attention.
Diagnostic support may include
- Fault-code scanning
- Warning-light assessment
- Symptom review and basic checks
- Guidance on the next diagnostic or repair step
- Workshop referral or coordination when deeper testing is required
A fault code is a starting point, not always the final diagnosis. The vehicle symptoms and supporting tests still matter.
