CAN and LIN Bus Fundamentals

CAN AND LIN BUS FUNDAMENTALS CP0607

This course gives an introduction to the use of CAN buses and LIN buses in automotive applications. It is a
practical course designed to teach students the basics of CAN and LIN bus connections and voltages, and it
also teaches students how to debug faults in CAN and LIN systems.

The course makes use of the Matrix CAN bus system: this consists of 6 educational Electronic Control Units
and accompanying Locktronics boards which mimic the electrical system in a vehicle. The system includes 3
CAN bus networks at different speeds, a LIN bus and a Gateway ECU which provides communication between
the system and OBDII scan tools.

The CAN and LIN bus system can be enhanced through the addition of real automotive sensors that are
added to the system.

Learning objectives:

• CAN and LIN bus wiring
• ECU function
• Network topology
• CAN and LIN bus
• Using scan tools
• Debugging CAN bus systems with a multimeter
• Circuit design for fault detection
