Tumble system
The tumble system is made up of diaphragms commanded according to the characteristic diagram of the engine,
and are used to restrict emissions. The diaphragms are closed (so the valve is disabled) at low speed and low load.There are two operation speeds depending on the water temperature.

cylinder.
The intake manifold diaphragms are opened, releasing the entire section of the duct when power is demanded of
the engine. All diaphragms of a cylinder bank are fastened to a common camshaft.
The position of the intake manifold diaphragms for each cylinder bank is checked by the Hall sensors which, in the
event of incorrect reading, send the information to the ECU that turns on the engine malfunction warning light. This information can be seen using the LaRa-AS .
The intake manifold diaphragms are enabled by a cylinder bank vacuum positioner in the engine for high rotation
speeds. Feedback of the position of the diaphragms is provided in this case as well, through the Hall sensors. In
the case of malfunctioning, they send the information to the ECU. Also in this case the errors can be read using the LaRa-AS .
The system is in stand-by (therefore enabled) with the engine cold, TH2O < 60°C, and with a torque demand
< 40% beneath 2000 rpm.
The system is operating (therefore disabled) with the engine hot, TH2O > 60°C, and with a torque demand < 40%
beneath 3000 rpm. The activation solenoid valve for the vacuum system is underneath the intake manifold: • it is enabled when the intake manifold is closed
• it is disabled when the intake manifold is open

On Off over 2000 rpm > 40% < 60°C
On Off over 3000 rpm > 40% > 60°C
Malfunctioning is detected by the LaRa-AS system and can be caused by a lack of vacuum
(therefore, leakage in the circuit) or in the two position detection sensors.

Lifting System
This is an hydraulic device enabling to lift the front part of the vehicle when driving at low speed, to allow access to areas with uneven surfaces. The system is composed of the following components: •
Front shock absorbers;
• Electronic control unit (GFA);
• Ascent or descent control button;
• Connecting hoses and electric wires.

B. Electronic control unit (GFA)
C. Ascent or descent control button
D. Lifting System
The system can be activated up to the maximum speed of 70 Km/h (30 Km/h for Japan); when it reaches this speed threshold the system will automatically go to the DOWN position. The system is activated:• with engine on only by means of LDAS-32 (109100) to perform diagnosis and operational tests.
• with a speed lower than 70 km/h (30 km/h for Japan).
• when the thrust mode function is not activated.
The system is deactivated:• when there is a problem on the ABS ESP system.
• when there is a problem concerning the UP or DOWN sensor.
• when the electric pump absorption is too high.
• when an incorrect vehicle speed signal is read.
The warning light on the dashboard will blink quickly to signal errors (it blinks slowing during raising/lowering).

During braking the ABS function allows the modulation of the braking force effectively applied to each wheel, thus preventing one or more wheels from becoming blocked, which would otherwise cause the loss of control of the vehicle.
The control unit carries out the corrections to the braking by reading the relative speed of each wheel, obtained by special sensors (pick-up).
To guarantee a good signal quality, the distance between the pick-up and the phonic wheel must be between 0.9
÷ 1.0 mm. The electro-hydraulic control unit carries out all the corrections on the braking, using 4 ISO valves and 4
DUMP valves. When an ISO valve is closed, the disc brake calliper is isolated from the hydraulic pump.
The DUMP valve, on the other hand, is used to reduce the pressure of the corresponding disc brake calliper that
is present in the hydraulic circuit. If, during normal use of the vehicle, the ABS warning light on the dashboard is
switched on and the buzzer sounds at the same time, it means that the ABS control unit has found a fault in the
system. When the warning light is on the ABS does not work; this means that in the vehicle the braking system works
anyway, but the electronic control on the braking is deactivated. $ % 6 V \ V W H P Y D F X X P U H F R Y H U \ S X P S
The electric vacuum recovery pump is positioned in the front bumper area and is controlled by the MASTER engine injection control unit only with the engine running.
Its operation is determined by a pressure sensor that calculates its drop and makes the pump cut in to maintain the vacuum. Its operation can be checked by means of the LaRa-AS engine control unit “01” Basic setting 8 (109000).

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.
