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 an incompatible yaw rate and acceleration sensor (airbag ECU assembly) is installed and the skid control ECU (brake booster with master cylinder assembly) receives a signal differing from the yaw rate and acceleration sensor that should be installed, the skid control ECU (brake booster with master cylinder assembly) judges that the signal is abnormal and illuminates the MIL and stores this DTC.
