Abstract

A method for testing an airbag release circuit for proper operation using a single test pulse. A single test pulse of predetermined form is delivered to the circuit in place of an accelerometer signal. The form of the test pulse permits determination of an expected resultant circuit output signal. The actual circuit output signal is compared to the expected signal to confirm or deny proper operation of the circuit. The test pulse can be modified to different forms to test individual aspects of the circuit.
