Height Control Valve: Removal

NOTE:

Before replacement, press the height control OFF switch to stop the vehicle height control operation.
Be careful that the vehicle body lowers because the air in the pneumatic cylinder is discharged by disconnecting the pneumatic cylinder side air tube of the height control valve.
This operation takes out the air from the front shock absorber, therefore never rotate the lower part of the absorber by turning the steering wheel etc..
