Description
1. Overview
Autoliv Sim.Mod. B0760 (627913600B) is an original factory SRS airbag system simulation load module, specially designed for automotive passive safety system maintenance, fault diagnosis and commissioning. It accurately simulates the electrical load parameters of original vehicle dual front airbags, effectively eliminating SRS fault codes, warning light activation and control unit locking caused by airbag disassembly.
Adopting automotive-grade high-precision resistance array and reinforced compact structure, the module features stable resistance value, low temperature drift and strong working condition adaptability. With plug-and-play design, it supports vehicle no-load power-on detection, bus communication test and electronic control debugging. It is a standard professional tool widely used in vehicle after-sales maintenance, electronic control commissioning and technical renovation scenarios.
2. Technical Features
2.1 High-Precision Equivalent Load Simulation
Equipped with high-precision SMD power resistors, it replicates the original vehicle airbag load characteristics with a tolerance within ±5%. The resistance value remains stable without drift or offset, enabling the SRS control unit to recognize normal hardware status and completely eliminate system fault alarms caused by airbag removal.
2.2 Wide Voltage Compatibility
Supports 3～12VDC wide working voltage range, perfectly adapting to 9V SRS control units and 12V vehicle electronic control systems. It features stable load performance without instantaneous current surge, ensuring reliable operation of vehicle safety electronic systems during debugging.

4. Operating Principle
The Autoliv Sim.Mod. B0760 module adopts high-precision resistance load equivalent simulation principle. The built-in 2.5Ω standard resistance array accurately replicates the electrical load characteristics of the original dual front airbags. When the original airbag is removed, the module is plugged into the original terminal to form a complete and stable electrical loop.
After vehicle power-on, the SRS control unit detects normal loop resistance and judges that the airbag hardware is connected normally, thus avoiding open-circuit fault codes, warning light activation and system control locking. The module maintains constant load resistance without drift or current fluctuation, ensuring normal operation of vehicle electronic control systems and bus communication during maintenance and commissioning.
After the debugging operation is completed, remove the simulation module and reinstall the original airbag. Clear fault codes and complete system self-check to restore the original vehicle safety system functions, realizing safe and standardized vehicle maintenance and technical renovation.
5. Application Scenarios
