21. Automotive in more detail

22. Methodology in automotive - starting
Students are advised to study Electricity, Magnetism and Materials before going on to advanced courses.
Students understand symbols, circuits, wiring, and theory
Students must get involved in wiring circuits
Students progress through ‘traditional’ subjects such as AC etc.

23. Methodology in automotive – sense and control
Students understand:
systems and ECUs
Circuitry inside an ECU
ECU wiring
How software makes open and closed loop systems
Circuit configurations
Students work in pairs
Students build circuits with 5 or 6 wires

24. Methodology in automotive – CAN bus
Students:
Wire up each node
Test each node
Students work in pairs or groups of 4
Each circuit contains up to 14 wires

25. Methodology in automotive – CAN bus
Students wire up the whole system and use the admin /scan node to discover how the system works. This looks very difficult
But students build it slowly and gain confidence in wiring

26. Key learning points about the CAN bus program
