DTC C1440: Steering Angle Sensor Unusual Bank Angle Detected [10/2018 - ]: Description
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2024 Lexus UX 250h, 2023 Lexus UX 250h, 2022 Lexus UX 250h, 2021 Lexus UX 250h, and 2020 Lexus UX 250h. However, it is still accessible from the selected car via links, so may be relevant.
If the skid control ECU (brake booster with master cylinder assembly) determines that the vehicle is being driven at a steep bank angle, the skid control ECU (brake booster with master cylinder assembly) stores DTC C1440 while VSC operation is temporarily disabled.
This is not a malfunction if the system and sensor circuits are normal and normal VSC operation resumes.
