ABSTRACT:
A method for disposing of a pyrotechnic safety device includes providing an electronic control unit having a primary control unit and an auxiliary control unit. The auxiliary control unit includes a safing mode and a scrap mode, and operates in the safing mode in an initial state. The auxiliary control unit is switched from the safing mode to the scrap mode when the primary control unit sends a first predetermined signal. The auxiliary control unit is armed only if it receives a second predetermined signal from the primary control unit while the auxiliary control unit is operating in the scrap mode. The primary control unit sends the first and second predetermined signals to the auxiliary control unit based on signals the primary control unit receives from an external source. The primary control unit then disposes of a pyrotechnic safety device (PSD) by sending a deployment signal to the PSD based on another signal received from the external source.
