Components

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 modules:

• to driver's Air Bag Q9, via the steering wheel clockspring Q10 (via pins 21 and 22):
• to the passenger airbag Q11 (pins 23 and 24).

Pin 7 is connected to the passenger Air Bag disabling key; via H65 it is possible to exclude the intervention of the passenger Air Bag in the case of an impact. 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 failure 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. Similarly, pin 9 of M60 sends the signal for the 'passenger disabling' warning light. The autodiagnostic data can be read by connecting to connector R10; The control unit sends diagnostic signals, via pin 3, to connector R10.
