This electronically controlled system allows the suspension to be adapted to the current driving conditions in order to improve road holding and passenger comfort
ECU-controlled actuators integral with the shock absorbers adjust the pattern of absorption according to the data transmitted by the various sensors
In certain conditions (poor road surface, tight bends, deceleration, acceleration), the ECU automatically controls the stiffness of the suspension (passing from the COMFORT position to the SPORT position)
When driving conditions return to normal, the ECU returns the system to the COMFORT position
The ECU incorporates two automatic patterns
- Suspension switch released, the ECU gives priority to the COMFORT position
- Suspension switch operated, the ECU gives priority to the Sport position, when stationary the suspension is in the Comfort position when driving, depending on the information transmitted by the various sensors, the ECU controls the actuators more easily for Sport suspension
The ECU has a memory which stores faults permanently even if the ignition is switched off or the ECU connectors are disconnected
If a fault is no longer present, it is cleared from the memory after the ECU supply has been switched on and off 50 times
Логика приведения в действие световые сигнализаторы
(1) световой сигнализатор V7700
(2) световой сигнализатор 7710
Нормальное функционирование
As soon as the ignition is switched on, the V7700 and 7710 warning lights illuminate for 3 seconds then extinguish
During this test, the ECU checks its internal circuits as well as the system components
When the suspension switch is pressed, the 7710 warning light comes on (SPORT position)
Обнаружение ошибок
When one or more faults are detected during switching on the ignition and normal operation, there are three possible causes
Shock absorber motor or sensor faulty
- Сигнализатор V7700 загорелся
- The 7710 warning light flashes continuously
ПримечаниеThe warning lights are illuminated until the ignition is switched off
When the ignition is next switched on, the warning lights will not illuminate again but the fault will be stored in the memory
V7700 warning light circuit faulty
- The 7710 warning light flashes for 15 seconds
- После включения зажигания
- Immediately following the appearance of the fault
ECU or ECU internal supply circuits faulty: the V7700 and 7710 warning lights illuminate
ПримечаниеAn ECU permanent memory fault, battery voltage too high, ECU connectors disconnected, or one or more of the ECU supply wires cut will not lead to warning lights coming on
