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.

The skid control ECU (brake booster with master cylinder assembly) monitors the voltage of the ABS motor. When the ABS motor relay is instructed to be off and the voltage of the ABS motor is at a value that is not possible when normal, the skid control ECU (brake booster with master cylinder assembly) judges that the circuit of the ABS motor is malfunctioning and illuminates the MIL and stores a DTC.
