This is a “passive safety system” since it comes into action once a certain deceleration value is exceeded (which can
only result from hitting an obstacle) without the occupant acting in any way. The deployment conditions of the airbagare governed by an electronic control unit (SDM) that continuously processes vehicle deceleration. An electric pulse

Please note that the gas generator is the only airbag system component containing a pyrotechnic charge.
The SDM is the control unit governing all the airbag system functions. The SDM is the only control unit in the system.
It contains both the accelerometer and the error memory. If the airbag warning light on the dashboard turns on during
normal vehicle operation, it indicates an airbag system malfunction. The malfunction will be stored in the SDM control
unit as soon as the dashboard warning light turns on. The airbag warning light indicates a failure without specifying
its nature. Run the SDM control unit diagnostic procedure to verify the cause of the error. The LARa-AS diagnostic system diagnoses the airbag control unit. To reset the system, see Gallardo Diagnostics.

The electronic control unit governs and activates the various airbag modules and is secured to the car’s tunnel under the console (Fig.1).
The control unit is connected to:• front airbags (driver side airbag module and passenger side airbag module)
• LH and RH side airbags
• LH and RH seatbelt pretensioners
• LH and RH side impact sensors
On the inside, the control unit has: • an electromechanical sensor which discriminates the “activation/deactivation” conditions according to the
vehicle’s longitudinal deceleration;
• an electromagnetic safety sensor operating with the electromechanical sensor; both sensors must enable the
“activation” condition for the system to be deployed;
The electronic control unit analyzes the signals coming from the internal and external sensors (side impact) and,
based on appropriate strategies (which consider the impact’s force and angle), normally activates: • In the case of frontal impact : the driver side airbag module, the passenger side airbag module and the two
seatbelt pretensioners.
• In the case of side impact : the side airbag and the seatbelt pretensioner on the side of the impact.
The control unit has a self-diagnostic feature that checks the entire system’s operation when the ignition key is turned
to “ON”. During the test a red warning light on the dashboard turns on. The warning light turns off approximately four
seconds after the engine is started if the system is working correctly.
