Can-FD Networking Management

CAN-FD 

The CAN-FD uses partial networking which is a selective wake-up function in an ECU that determines the CAN bus messaging for a specific corresponding task, allowing an ECU to use less overall current and energy. This can be used when updating (flashing, downloading, and messaging) ECU software during service.

The CAN-FD networks use different classifications for ECU communication.

• Responsive = The ECU is allowed to wake up or be awakened by CAN messages, when the ignition is off.
• Passive Responsive = The ECU receives a message that causes the ECU to begin sending messages on that CAN.
• Non-Responsive = The ECU is not allowed to wake up or be awakened by CAN messages, when the ignition is off.

CAN-FD ECU network classifications are listed as follows:
