Passenger air bag disablement warning light

Passenger air bag disablement warning light
  • A, Disabling key in OFF position: seat empty or occupied
  • B, Disabling key in ON position: seat empty, then occupied (T1), then empty again (T2)
  • C, Disabling key in ON position: seat empty, then occupied (T) within 30 seconds
  • PASS., passenger Air Bag enabled = ON, disabled = OFF

During starting (key in ON position), the orange coloured "passenger Air Bag disabled" warning light comes on for around 4 seconds.

  • if the key for the manual disabling of the passenger Air Bag is switched OFF, the warning light remains on.
  • if, on the other hand, the key is switched ON, the warning light flashes for a further 4 seconds and then goes out (only up to 5/99).

If, with the key in the ON position, the automatic passenger Air Bag disabling sensor signals a change from the "empty" to the "occupied" condition, the control unit makes the warning light flash for 4 seconds.

NOTE:

This does not take place in the reverse situation (change from "occupied" to "empty").

The diagram illustrates the logic for switching on the warning lights starting with the "ignition in the ON position".
