Description

DESCRIPTION

The car is fitted with an electronically-controlled safety system which, in the case of a front-end crash of some severity, activates the driver's Air Bag. The electronic control unit manages the entire system, checking all the components and when necessary activating the Air Bags.

The control unit is located under the centre console and is rigidly fixed to the bodyshell; in this way the deceleration sensors located inside it are close to the centre of gravity and detect deceleration for the entire vehicle accurately.

The driver's Air Bag module is located in the centre of the steering wheel; it is fitted on a tilting plate which enables the horn to be operated. The plate houses a metal container which holds the folded airbag and a gas generator that inflates the bag.

A clock spring device allows the airbag module connection leads to turn with the steering wheel without the risk of breakage.

The control unit comes with a self-diagnostic function.

• it detects and memorizes any faults
• it recognizes the various components and the type of fault
• it signals the onset of these faults via the special warning light

System activations following a particularly serious impact are memorized by the control unit.

For more details Characteristic of working principle 5580C Air bag system . The system control unit supply line is protected by a fuse located in the junction unit.

When operations are carried out to the Air Bag system the recommended safety instructions must be followed precisely. For further details see PROCEDURES 5580C
