Development Backgrounds:
The sensor is the signal input device of the vehicle ECU. It converts vehicle operating parameters such as vehicle speed, coolant temperature, engine speed, air flow, and throttle opening into electrical signals and sends them to the vehicle ECU. Then, the vehicle ECU adjusts the engine running status to maintain the engine in optimal condition. 

X431 S2-2 Sensorbox Main functions:

• ECU Troubleshooting and Diagnostics
• A unique feature is the ability to simulate of "hand-drawn" signal.
• Test and simulate most vehicle sensors, quickly troubleshooting the ECU.
• Simulate some special working condition of sensors without replacing parts
• Be used as Multimeter to measures resistance, voltage AC/DC, capacitance, frequency and pulse signals, etc.
• Wave forms can be altered or made from scratch using nothing more than your finger tip and the screen
• Allows you to test DC voltage, fixed frequency, predefined waveforms and hand drawn waveforms
• Allows the user to substitute known good waveforms for isolated elements that could not otherwise have been authenticated
• Simulation of DC signal, pulse signal, predetermined waveform signal simulation - sine waveform, simulating signal of oxygen sensor, mass air flow, injector, throttle position and other.
• S2-2 Sensorbox is specially developed for diagnosing/simulating sensor faults. It mainly includes “Sensor”, “ Actuator”, “Defined/Drawn”, “Timing Waveform“ and “ multimeter”.

Defined

• Waveform: There are 9 waveforms to choose; Forward sine wave, reverse sine wave, forward square wave, reverse square wave, medium voltage, straight line, high / low voltage straight line, triangle wave, and trapezoidal wave.
• Frequency: Set the frequency of the selected waveform.
• Amplitude: Set the amplitude of the selected waveform.
• Offset: Set the offset of the selected waveform.
• Phase: Set the phase of the selected waveform.
• Duty cycle: Set the duty cycle of the selected waveform.
• Signal sync: Can cause CH1 and CH2 to output signals at the same time.

Hand-drawn

• Total frame: 1-3 (optional). Indicate the total number of output points
• Generally, one waveform is composed of 100 points. The values 1-3 indicate that you can select 100, 200, or 300 points to form a waveform.
• Edit frame: You can edit a single frame or edit all
• Waveform: You can select a preset waveform and place it in the hand-drawing area
• Frequency: Frequency of a single frame (for 3-frame output, the total frequency is the set frequency/3)
• Amplitude: Amplitude of the output waveform
• Offset: Offset of the output waveform
