U0060Vehicle Communication Bus D (-) Open
- Generic OBD-II code · Network
- How the car detects it
- U0060 stands for a break in the (-) line of Vehicle Communication Bus D, CAN-Low on a two-wire CAN such as Bentley's private chassis network. Nodes cut off by the break still see CAN-High move, but a high-speed receiver judges only the voltage difference between both wires, so frames from the other side become unreadable to them. NXP notes that a high-speed transceiver has no way to detect a line interruption itself, which leaves time-outs and missing acknowledgements as the evidence. NXP also designed the wake-up detection of its TJA1041 so that a CAN-Low interruption causes no unwanted wake-up while the bus goes to sleep. No manufacturer documents U0060 publicly. Test CAN-Low continuity between the modules, starting with connectors recently opened.
