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 voltage of the pump motor.

When the voltage of the pump motor is practically equal to that when on for a long period of time, the No. 2 skid control ECU (brake actuator assembly) judges that the pump motor is operating for an abnormally long time and illuminates the MIL and stores a DTC.
