OBD-II is an improvement over OBD-I in both capability and standardization. The OBD-II standard specifies the type of diagnostic connector and its pinout, the electrical signalling protocols available, and the messaging format. It also provides a candidate list of vehicle parameters to monitor along with how to encode the data for each. There is a pin in the connector that provides power for the scan tool from the vehicle battery, which eliminates the need to connect a scan tool to a power source separately. However, some technicians might still connect the scan tool to an auxiliary power source to protect data in the unusual event that a vehicle experiences a loss of electrical power due to a malfunction. Finally, the OBD-II standard provides an extensible list of DTCs. As a result of this standardization, a single device can query the on-board computer(s) in any vehicle.
U281 is a kind of auto device for reading and erasing trouble code in vehicles, sometimes called car reader. With a U281, you may quickly find out trouble causes (troubleshooter) of electronically controlled systems on your car, by simply connecting U281 with the diagnostic socket, via reading the trouble code (DTC) shown on U281, identifying, locating and checking out trouble causes with attached user's manual.
