CAN standards
A controller area network bus (CAN bus) is a vehicle bus standard.
- Differential signaling
- CRC
ECU Electronic Control Unit
CAN 2.0 (classical CAN)
- eight bytes
- a typical baud rate of 500 kbit/s
- CAN2.0A, CAN2.0B,
CAN FD (releases 2012).
Some de facto standards for mechanical implementation: 9-pin D-sub type male connector
- pin 2: CAN-Low (CAN−)
- pin 3: GND (ground)
- pin 7: CAN-High (CAN+)
- pin 9: CAN V+ (power)
CAN C - Engine CAN (also known as chassis CAN): Fast communication speeds 125 kbps or 500 kbps
CAN B - Interior CAN (also known as body CAN): Communication speed 83 kbps
