How you'll learn
The course is delivered 100% online on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within each intake, so it fits around your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is KiCad, QElectroTech, Zuken E3.series and Microsoft Visio, in free, academic or evaluation versions. Testing is studied through real procedures: harness manufacture on a board, electrical modernisation of classic motorcycles and preparation of historic vehicle application files. Assessment is continuous by module, plus the final project.
Standards covered: Real Decreto 892/2013, Real Decreto 866/2010, Vehicle Modifications Manual, ISO 6722, ISO 8820, SAE J1128, UNECE Regulation No. 53.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
