Monitor Description

WARNING: This page is about a different car, the 2025 Lexus NX 350h, 2024 Lexus NX 350h, 2023 Lexus NX 350h, and 2022 Lexus NX 350h. However, it is still accessible from the selected car via links, so may be relevant.

When the brake pedal is not operated and the servo pressure sensor output value exceeds a specific value, or the value is less than a specific value for a certain amount of time, the No. 2 skid control ECU (brake actuator assembly) judges that the zero point of the servo pressure sensor is abnormal and illuminates the MIL and stores this DTC.
