In the description of OBD scanner, there is a function of reading data stream. What is data stream? What's the use of it?
Vehicle data stream refers to the data parameters that ECU communicates with sensors and actuators. It can be read by OBD scanner, OBD2 code reader or OBDii diagnostic tool through the diagnostic interface.
The data stream is real-time and changes with time and vehicle condition. The data flow truly reflects the working voltage and state of each sensor and actuator. User or maintenance personnel can take them as the input and output data of automobile ECU. And user can know the working condition of automobile at any time. It provides the basis for the automobile fault diagnosis, so as to diagnose the automobile fault in time. Through the data stream, you can also set the operation data of the car.
Generally, OBD scanner is able to monitor data streams as follows:
① Throttle opening.
② Engine speed.
③ Coolant temperature at start-up.
④ Oxygen sensor working status.
⑤ Carbon canister command.
⑥ Injection pulse width signal.
⑦ Intake idle speed control.
⑧ Ignition advance angle.
⑨ Intake manifold pressure.
⑩ Air flow.
⑪ Intake air temperature.
There are two forms of data stream according to the display mode on the OBD scanner (APP). Numerical parameters and state parameters. Numerical parameters are parameters with a certain unit and a certain range of variation. It usually reflects the working voltage, pressure, temperature, time, speed, etc. State parameters are those with only two working states, such as on or off, on or off, high or low, yes or no, etc. It usually represents the working state of the switch and solenoid valve in the electronic control device.
So that’s the relations between OBD scanner and real-time data streams.
