CAN Bus : Under the hood (French)

The first of our automotive network courses – CAN and LIN bus fundamentals – gives an introduction to CAN
and LIN networks in vehicles and how to use multimeters, oscilloscopes and OBDII scan tools to diagnose
faults. This course takes the student a step further into CAN and LIN bus protocols and explains how they
are used to pass information between the ECUs in a vehicle. The course also gives an insight into how vehicle
designers construct a system of ECUs and circuits to provide the functionality that modern vehicles require.
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. See our Automotive sensors product.
