Pedagogical approach

Pedagogical approach

Une journée de 10 heures pour comprendre les systèmes FBS Mercedes-Benz au niveau atelier, mieux identifier les limites d’intervention et structurer vos décisions techniques.

  • Progression structurée : architecture, données, compatibilité, scénarios, FBS4 et restitution.

  • Études de cas : dossiers documentés, lecture de symptômes et analyse de situations atelier.

  • Démonstrations encadrées : identification des boîtiers, des familles de composants et des interfaces.

  • Approche responsable : repérer les cas qui demandent l’intervention d’un réseau constructeur ou d’un partenaire autorisé.

  • Matériel pédagogique : boîtiers EIS/EZS, ESL/ELV, maquettes de communication et supports illustrés.

Team and resources
Deux formateurs interviennent pendant la journée. Vous travaillez en petit groupe avec des boîtiers et maquettes pédagogiques, des postes de travail, des schémas de chaîne FBS, des fiches de décision atelier et des supports interactifs.

Monitoring and evaluation
Une évaluation d’entrée vérifie votre expérience en atelier, vos bases de diagnostic électronique et votre maîtrise des règles de sécurité. En fin de journée, une étude de cas et un questionnaire permettent de valider votre capacité à identifier une architecture, qualifier une situation, organiser les sauvegardes, renseigner la traçabilité et orienter une situation lorsque cela est nécessaire.

90-hour active training: intensive practice and gradual empowerment in engine control programming.

  • Spiral progression: fundamentals followed by advanced skills

  • Projects on real ECUs and professional cases (stage 1, E85)

  • 50 hours in-person (hands-on, demos) + 40 hours e-learning (theory, tutorials)

  • Mastery of tools (Kess, Winols…) and security (checksums, compliance)
