*Note: Choose corresponding cables and test probes according to different terminals.
9.3.2 Simulation test
Simulation test enables users to exactly judge if the sensor is good or not to
avoid replacing components blindly. For example, the trouble code indicates the
fault is in water temperature sensor itself. But we need to confirm whether the
fault results from water temperature sensor or the connections between ECU
and sensors, or ECU itself. In this case, we can make full use of simulation test
to input the signal of simulating water temperature sensor, instead of water
temperature sensor, to the microcomputer. If the engine works better and the
fault vanishes, the fault is in the water temperature sensor. If the fault still occurs,
input the signal to the corresponding terminals of ECU. Consequently, if the fault
disappears, the fault lies in the connection between water temperature sensor
and ECU, otherwise, the fault exists in ECU.
After all connections are properly made (refer to Chapter 9.3.1 for details), turn
the tablet on and enter the Home screen, then tap “Toolbox” -> “Sensor” to enter
the test selection screen. See Fig. 9-2.

1. DC voltage simulation
In Fig. 9-2, tap [Current voltage], then tap “+” or “-” to adjust the output voltage
value. Alternatively, user can also tap edit box, then use the on-screen keyboard
to input the desired value directly. After selecting or inputting the desired voltage
based on the working characteristics of sensor, tap the
button, then the
X-431 PAD III will begin to output the simulation voltages. Please note the red
