Operation - Fiat TIPO 2015 Mode D'emploi

NOTE:
 the control unit must always be fitted with the arrow printed on the adhesive plate
facing in the car's direction of travel.
Always check that there are no foreign bodies between the control unit and the body

and tighten the screws to the prescribed torque.
If the control unit falls to the ground or is subject to abnormal impact during handling,

it MUST be replaced.
The control unit contains an electronic deceleration sensor that enables safety device activation. This
sensor consists of bi-directional accelerometers integrating the ECS front sensor and enhancing the
function of the side sensors.

Operation

Side impact:
When there is a side impact, the control unit is capable of recognising the direction and intensity,
activating the two side bags and the pretensioners on the side affected by the impact. To provide total
cover against side impacts, two satellite sensors located in the centre pillars are used.
When a side impact takes place, the satellite sensors detect the impact signal directly along the
transverse axis of the car and send it to the control unit. This signal, processed by the control unit
microprocessor, makes it possible to determine the severity of the side impact and, as a result, decide
whether to activate the side bags on the side concerned, only if the control unit safety sensor gives the
activation enablement.
In a situation where side impact occurs together with the activation of the side bags (on equipped
vehicles) the activation of one of the two front passenger pretensioners is ordered on the side affected
by the impact. The side airbags (head bags and side bags) are activated simultaneously and
independently of the front safety devices.
After each activation of one of the controlled systems (pretensioners, front airbags, side bags), the
control unit stores the activation in its permanent memory and orders activation of the fault warning
light on the instrument panel.
Before it is replaced, the control unit guarantees activation of individual devices within the following
limits:
3 impacts with activation of the front seat belt pretensioners only;

3 impacts in total (right or left) with activation of the side bags;

1 impact with activation of pretensioners and front airbags;

any combination of the above-mentioned cases until the maximum number permitted has

been reached.
If one of the limits described is not reached, it will be possible to reuse the control unit once system
operating conditions have been restored. The final activation, corresponding to the maximum number
for the limits indicated, will prevent further reset procedures.
