Monitor Description

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2024 Lexus ES 300h, 2023 Lexus ES 300h, 2022 Lexus ES 300h, 2021 Lexus ES 300h, and 2020 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.

When the volume of brake fluid within the accumulator is below a certain amount, the skid control ECU (brake booster with master cylinder assembly) operates the pump motor. When the pump motor is being operated and the output value of the accumulator pressure sensor does not change substantially for a certain period of time, the skid control ECU (brake booster with master cylinder assembly) judges that the accumulator pressure sensor has a stuck malfunction and illuminates the MIL and stores this DTC.
