Understanding the ELM327 and Airbag Systems
The ELM327 is a microchip that acts as a bridge between your car’s onboard diagnostic system (OBD-II port) and your smartphone, tablet, or laptop. It translates the complex data from your car into a readable format. Airbag systems, crucial for safety, are also monitored by the OBD-II system. Faults in the airbag system, such as a deployed airbag, a faulty sensor, or wiring issues, will trigger diagnostic trouble codes (DTCs) stored in the vehicle’s computer. An ELM327 scanner allows you to access and interpret these codes.
