DTC C1419: Deceleration Sensor Internal Circuit; DTC C1435: Yaw Rate Sensor Internal Circuit [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.

The airbag ECU assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition using 2 circuits (GL1, GL2).

If an internal malfunction signal from the yaw rate and acceleration sensor (airbag ECU assembly) is detected by the skid control ECU (brake booster with master cylinder assembly), DTC C1419 and/or DTC C1435 is stored.
