Tip: When detecting the faulty vehicle, if the display system is normal or has no fault
code, it means that the relevant fault code is not stored in the ECU or some fault
phenomenon is not within the ECU monitoring range, which is mostly a mechanical
fault. It is also possible that the sensor has a signal deviation in the range, which can
be judged in the data stream function.
3Read data stream
By reading the data stream function, it is possible to read the data value of the control
unit.
4Action test
Follow the prompts, for example: the engine is not running and the ignition switch is
on. If the engine is started or the speed signal is recognized, the motion test is forced
to be interrupted.
