Composition of the Built-in Hydro-electronic Interface:
- An electric motor.
- A pump with 5 pistons.
- 4electrovalves.
- 2non-return valves.
- A pressure limiter.
- An anti-pulse accumulator.
- A filter.
- The suspension ECU.
Features of variable damping suspension.
Variable damping suspension ECU (CSS).
The ECU (CSS)is located in the engine compartment, in the ECU tray.
The ECU (CSS)manages the different damping laws, as a function of the information delivered
by the following components:
- The 4wheel travel sensors.
- The 2suspension pressure sensors.
- The speed of the vehicle.
- The speed of rotation of the steering wheel.
The suspension ECU (CSS)pilots the following components:
- The 4variable damping suspension actuators.
- The Built-in Hydro-electronic Interface (BHI).

(9)Front RH wheel travel sensor
The wheel travel sensor defines the angular position of the suspension lower arm.
Identification of the sensors:
- Front RH wheel travel sensor: Yellow.
- Front LH wheel travel sensor: Red.
- Rear RH wheel travel sensor: Green.
- Rear LH wheel travel sensor: Blue.
IMPERATIVE: Before operating on a wheel travel sensor, uncouple its rod so as not to
go past the maximum angular travel (see corresponding operation).
The suspension pressure sensors (7)informs the suspension ECU (CSS)of the pressure in
the hydraulic high pressure pipes of the front suspension.
The sensor (13)informs the suspension ECU (CSS)of the pressure in the hydraulic high
pressure pipes of the rear suspension.
