Code C1764 Lexus Description

The solenoid valve is located in the No. 1 height control valve. When the vehicle height is adjusted, the fluid line is opened or closed according to the signal from the suspension control ECU. If the height control pump and motor activates when the fluid line is closed due to the solenoid valve malfunctioning, the solenoid valve being stuck, or foreign matter clogging the fluid line, fluid pressure increases abnormally. When this problem with the fluid pressure is detected, DTC C1764 and/or DTC C1765 is stored.
