6 SYSTEM OUTLINE This system consists of a pneumatic cylinder which has pressured air in an air chamber, an ECU which automatically switches vehicle height between two ranges (Normal and high) according to the driving conditions and also two () modes (Normal and high) which the driver can choose from according to preference. lso, the damping force of the shock absorber is automatically switched by the ECU among nine levels (Soft to hard). Combined control of vehicle height and damping force suppresses changes in the vehicle s attitude such as roll, nose dive and squat to provide outstanding riding comfort and controllability.. INUT SINLS () Steering sensor signal Rotation angle of the steering wheel is input to TERMINLS SS and SS of the air suspension ECU. () Throttle position sensor signal The throttle valve opening angle is detected and the signal is input to TERMINL L of the air suspension ECU via the engine control module. () ehicle speed sensor signal The vehicle speed is detected by the vehicle speed sensor and the signal is input to TERMINL SD of the air suspension ECU. (4) Stop light SW signal The brake operation signal is detected and the signal is input to TERMINL ST of the air suspension ECU. (5) Height control SW signal Whether the height control SW is in normal or high mode is detected and the signal is input to TERMINL HSW of the air suspension ECU. (6) Height control sensor signal The vehicle height and the different levels of the road surface are detected by the height control sensor and the signal is input to TERMINLS SHFL, SHFR, SHRL and SHRR of the air suspension ECU. (7) Door courtesy SW signal Whether the door is open or closed is detected and input to TERMINL DOOR of the air suspension ECU.. IR SUSENSION OERTION High position Signals from the vehicle speed sensor, height control sensor and so on are input to the air suspension ECU, which operates so that the current flows from the air suspension ECU to front and rear height control valve to open the pneumatic cylinder valve. s a result, the passage is opened as far as the height control dryer. Then, the current flowing to the IR SUS relay flows to the height control compressor. Control of this current by the air suspension ECU causes the compressor to operate and air flows into the pneumatic cylinder to raise the vehicle height. Low position Signals from the vehicle speed sensor, height control sensor and so on are input to the air suspension ECU, which operates so that current flows from the air suspension ECU to front and rear height control valve to open the pneumatic cylinder valve. s a result, the passage is opened as far as the height control dryer. Then, the current flows to the height control exhaust valve installed in the height control dryer. Control of this current by the air suspension ECU causes the valve to open so that the air inside the pneumatic cylinder is expelled and the vehicle height is lowered.

7 ELECTRONICLLY MODULTED IR SUSENSION. SIC OERTION OF SUSENSION CONTROL CTUTOR The suspension control actuator controls the damping force of the shock absorber inside the pneumatic cylinder in 9 steps. ased on signals from the acceleration sensors, vehicle speed sensor and stop light switch, etc., the suspension ECU controls the suspension control actuator to adjust the damping force of the shock absorber. s the following table shows, the damping force of the shock absorber is changed by the current flowing from TERMINL,, 4 and 5 of the suspension control actuators to TERMINL to ROUND. + round osition Terminal and Soft to Terminal and 4 to Terminal 4 and 5 to 4 Terminal 5 and 4 to 5 Terminal and 5 to 6 Terminal and 4 6 to 7 Terminal 4 and 5 7 to 8 Terminal 5 and 8 to 9 Hard SERICE HINTS (), 4 (C) IR SUSENSION ECU (C) ROUND : lways approx. volts (C) ROUND : pprox. volts with ignition SW at ON or ST position () ROUND : pprox. volts with stop light SW on (C)6 ROUND : lways continuity H0 HEIHT CONTROL EXHUST LE : pprox.
