Abstract
A diagnostic means is connected to various electrical locations in an air bag system to detect and process faults. When a fault is detected, it is assigned a unique code sequence consisting of equally spaced pulses of equal length. The number of pulses determines the fault which is indicated by a single light inside the car.
