3 Sensor Simulation

3.1 Connection

1. Firstly power on the main unit (connect the main unit module and the DC
12V power supply via the power adapter, or powered via cigarette
Lighter cable and the two clamps battery cable);
2. Connect the sensor test cable (black) to the "COM" interface on the
sensor module by one end, then connect the test probe or electric
control convertor cable by the other end;
3. Connect the sensor test cable (red) to the "VΩHz" interface on the
sensor module by one end, then connect the test probe or electric
control convertor cable by the other end;
Notice: choose related cables and test probes according to different terminal.

3.2 Start simulation test

With simulation function users can exactly judge if the sensor is good or not,
which can decrease replacing components blindly. For example, the trouble
code indicates the fault is in water temperature sensor itself. But we need
also make sure the fault is in water temperature sensor or in the connection
between ECU and sensors or in ECU itself. So at this time, the signal of
