HOLDEN claims Barina's electrical and electronic systems are characterised by fast data flow, intelligent control methods and weight-saving design. They are operated by two controller area network (CAN) data buses, which facilitate simpler, more efficient communication between vehicle systems. A high-speed (500 kilobits per second) 'bus' serves systems that require quick reaction and implementation times - safety controls and engine functions, for example - while a lower-speed (47.5 kilobits/second) unit handles items such as lighting, windscreen wipers and door locks.
