Monitor Description

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2024 Lexus RC 300, 2023 Lexus RC 300, 2022 Lexus RC 300, 2021 Lexus RC 300, and 2020 Lexus RC 300. However, it is still accessible from the selected car via links, so may be relevant.

The ECM monitors the speed of the electric water pump assembly. If the actual speed exceeds the target speed by a certain amount or more, the ECM determines overspeed operation has occurred. If the actual speed is less than the target speed by a certain amount or more, the ECM determines that the motor is stuck and stores a DTC.
