ASMBox™ – OBD Failure Simulation
One Solution covering all signal failure patterns.
The ASM Box™ allows efficient verification of PVE and OBD calibration via modulation of actuator and sensor signals, especially for U.S. homologation with government mode in addition to the common user mode. Because no faulty hardware is required for failure generation, it achieves cost savings of at least 20 percent in typical use cases. Using the ASM Box for automated drifting of sensor signals for robustness testing improves quality as well as efficiency.
