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.

During normal operation, the voltage at IGR and IGP changes mutually; however, if the voltages do not change mutually such as when IGR is off and IGP is on, the No. 2 skid control ECU (brake actuator assembly) judges that the power supply voltage of IG is excessively low, and illuminates the MIL and stores a DTC.
