DTC C1737/31: Right Front Height Control Solenoid Valve Circuit; DTC C1738/32: Left Front Height Control Solenoid Valve Circuit; DTC C1739/33: Right Rear Height Control Solenoid Valve Circuit; DTC C1740/34: Left Rear Height Control Solenoid Valve Circuit: Description
- The height control valve sub-assembly No. 1 independently opens and closes paths to the pneumatic cylinder for the front wheel side by receiving the signal from the suspension control ECU. The height control valve sub-assembly No. 1 continues its operation for max. 60 seconds after the ignition switch is turned off. This takes place in order to discharge the high pressure air which is produced when the vehicle's height is lowered by the auto leveling function and in the access mode.
- The height control valve sub-assembly No. 2 independently opens and closes paths to the pneumatic cylinder for the rear wheel side by receiving the signal from suspension control ECU. The height control valve sub-assembly No. 2 continues its operation for max. 60 seconds after the ignition switch is turned off. This takes place in order to discharge the high pressure air which is produced when the vehicle's height is lowered by the auto leveling function and in the access mode.
