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.

The No. 2 skid control ECU (brake actuator assembly) monitors the relationship between the specified decrease in servo pressure and the target brake fluid pressure.

When the brake pedal is released or while braking is being performed and the relationship between the servo pressure and the target brake fluid pressure is outside of the normal range, the No. 2 skid control ECU (brake actuator assembly) judges that the decreasing pressure is abnormal and illuminates the MIL and stores a DTC.
