Automotive lighting with CAN data bus

With more data transmission and networking in the motor vehicle, networked control units also take over the management of the lighting and electrical system in modern passenger cars. The educational system consists of a steering column switch with control unit and the electrical system control unit to activate the front and rear lights. It can be expanded with a comfort control unit, an instrument cluster with integrated gateway and a control unit for automatic trailer detection.

The experiment can study modern control unit functions, such as

• Cold lamp monitoring
• Hot lamp monitoring
• Turn signals
• Daytime running lights
• Automatic headlights
• Automatic ambient lighting, or
• PWM-controlled taillights.

Furthermore, measurements relevant to the workshop can be executed on the low-speed and high-speed CAN data buses. The lockable fault simulator (738 585), which can override practical faults in addition to all the standardized faults per ISO, lends itself to the students' troubleshooting procedure, and so does the remote-controlled automotive fault simulator (738 491).
