Description
LAUNCH • X431 sensorbox S2-2
The LAUNCH X-431 sensorbox S2-2 is a professional diagnostic module designed for vehicle technicians, developed to test, simulate, and measure most vehicle sensors and actuators. Constructed with robust hardware supporting two independent channels, it offers voltage simulation up to 20 V, frequency generation, waveform drawing, and full multimeter functions. The module requires compatibility with LAUNCH X-431 scanners (such as PAD V, PAD VII, PAD III V2.0, PRO5, Throttle V/III series) to operate. Intended for workshops diagnosing ECU wiring, sensor faults, or signal issues.
Key benefits
- Tests and simulates input signals of sensors (throttle, pedal, temperature, cam/crank, airflow, oxygen) without replacing parts
- Includes actuator mode for output signal simulation (solenoids, injectors, idle motor) to check component response
- Powerful multimeter functionality: AC/DC voltage up to 700 V, resistance to 40 MΩ, capacitance up to 100 µF
- Flexible waveform tools: 9 predefined shapes plus hand-drawn waveforms, adjustable frequency, amplitude, offset, phase, duty cycle
- Two independent channels with 1% precision, supports square wave generation up to 15 kHz and general signals up to 20 kHz
Supported protocols
- Requires LAUNCH communication protocols used in X-431 diagnostics series (USB connection to scanner) for data transfer and command execution
- CAN-bus and standard sensor signal types (voltage, frequency, PWM, inductive and Hall sensors) simulated and measured
Supported functions
Depending on vehicle compatibility the following functions are supported:
- Sensor input simulation (signal output to mimic sensor behavior)
- Actuator output signal generation (PWM, solenoids, injectors, ignition coils)
- Defined waveform generation (pre-set waveforms: sine, square, triangle, etc.)
- Hand-drawn/custom waveform generation (up to 300 points)
- Timing waveform mode (match crankshaft and camshaft timing signals)
- Multimeter measurements (voltage AC/DC, resistance, capacitance, frequency, diode test, continuity)
