The airbag DCU controls the operation of the system and also contains the collision detection sensors. The airbag

earth connects to one of the fixings. A multi-pin connector provides the airbag DCU connection with the vehicle
harness.

Incorporated into the airbag DCU is a mechanical safing sensor, an electronic single point sensor and integrated
circuits for control and diagnostics. The mechanical safing sensor is a normally open switch that closes at the preset
