💡

Meaning

The speaker is asking for the specific diagnostic code that identifies a problem, whether in a medical report, a car‑repair shop, or any technical troubleshooting context. It is a direct, informal way to request that piece of information.

🎯

When to use

Use this phrase when you need the exact code that classifies a diagnosis or fault, especially in informal conversations with a doctor, mechanic, or technical support staff. Switch to a more formal version (e.g., "Quel est le code de diagnostic ?") in written or formal spoken contexts.

✕Common Mistakes

  • Qu'est‑ce que le code de diagnostic ?

    The structure "Qu'est‑ce que" is used for "what does..." not for "what is..."; it sounds unnatural here.

  • C'est quoi le code du diagnostic ?

    Using "du" (de le) changes the meaning to "of the diagnostic" rather than "diagnostic code"; the correct preposition is simply "de".

  • Quel est le code du diagnostic ?

    Again, "du" is unnecessary; the idiomatic phrase is "le code de diagnostic".

↔Alternatives

  • Quel est le code de diagnostic ?

    What is the diagnostic code?

  • Pouvez‑vous me donner le code de diagnostic ?

    Could you give me the diagnostic code?

  • Quel code de diagnostic utilisez‑vous ?

Cultural Tip

In French, "C'est quoi..." is perfectly natural in spoken, informal settings, but it can sound too casual in a medical consultation or a formal report. In those cases, opt for "Quel est le code de diagnostic ?". Also, remember that "diagnostic" can refer to both health and technical fields, so the surrounding context will clarify the meaning.
