DTC C1290: Abnormal Zero Point of Steering Angle Sensor [06/2018 - ]: 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) acquires the steering angle sensor zero point every time the power switch on (READY) and the vehicle is driven at 35 km/h (22 mph) or more for approximately 5 seconds. The skid control ECU (brake booster with master cylinder assembly) also stores the previous zero point.

If front wheel alignment or the steering wheel position is adjusted without disconnecting the cable from the negative (-) auxiliary battery terminal, or if the yaw rate and acceleration sensor zero point is not acquired after the adjustments have been completed, the skid control ECU (brake booster with master cylinder assembly) detects the difference between the previous zero point and newly acquired zero point and stores this DTC to indicate a poor adjustment.

Warning operation for the steering angle sensor zero point malfunction will be canceled by turning the power switch off.
