The control unit for the Air Bag system M60 is controlled by the ignition (INT) at pin 2 by the line protected by fuse F23 of the junction unit B1, whilst pin 1 is connected to earth C50.
When an impact of a set severity (determined by the control software) is detected, the control unit sends control signals to set off the driver's Air Bag module Q9 via the clock spring on the steering wheel Q10 (pins 21 and 22).
When the system self-diagnostic function detects a fault or an impact is detected, control unit M60 sends a signal from pin 10 to the Air Bag fault warning light, located in instrument panel E50, switching it on. The instrument E50 is supplied by the line protected by fuse F22 of the junction unit B1.
The autodiagnostics data can be read by connecting to connector R10; The control unit sends diagnostic signals, via pin 3, to connector R10.
