Bonjour pas de voyant moteur test d un diag CarPal défaut apparu b3006:01 b3006:04 tout bêtement J ai changé le loquet mais toujours le problème comment tester cela merci

Bonjour,
Le code B3006 sur votre Chevrolet Silverado 2016 correspond au circuit du contact de capot (hood ajar switch). Le fait d’avoir remplacé le loquet (latch) mais de garder le même défaut indique que le problème est probablement ailleurs :
1. Vérifier le faisceau et le connecteur
- Inspectez le connecteur du capteur de capot pour traces d’oxydation, d’humidité ou de broches tordues.
- Suivez le faisceau du capteur jusqu’au module BCM (Body Control Module), cherchez des fils coupés, pincés ou abîmés.
2. Tester le capteur lui-même
Même neuf, il faut vérifier s’il fonctionne correctement :
- Débranchez le connecteur du capteur.
- Avec un multimètre, mesurez la continuité du switch en ouvrant et fermant le loquet. Vous devez avoir un changement d’état (ouvert/fermé).
- Si la continuité ne change pas, le nouveau capteur peut être défectueux.
3. Contrôler l’alimentation
- Vérifiez que le capteur reçoit bien sa tension de référence (souvent 5V ou 12V selon le circuit) et une bonne masse.
- Si la tension ou la masse est absente, le problème vient du câblage ou du BCM.
4. Codes de sous-type (01 et 04)
- B3006:01 = circuit bas ou court-circuit à la masse.
- B3006:04 = circuit ouvert.
Ces deux variantes orientent vers un problème de câblage ou connecteur, plus que du capteur lui-même.
👉 En résumé : commencez par tester la continuité du switch et inspecter le câblage/les connecteurs. Si tout est correct côté capteur, le souci peut venir du BCM, mais dans la majorité des cas sur Silverado c’est un problème de fil ou de connecteur endommagé.
