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 power switch is on (IG) and the fluid level warning switch (brake booster with master cylinder assembly) is on for a certain amount of time, the skid control ECU (brake booster with master cylinder assembly) judges that the brake fluid level in the reservoir is low and illuminates the MIL and stores this DTC.
