How to Reset the Steering Angle Sensor?

Steering angle sensor reset method: 1. Use a decoder to access 44 Power Steering, read measurement values, and perform steering wheel zero position adjustment; 2. Access 03 Brake Electronics, input 11 Login, access code 40168; 3. Select Basic Settings, follow prompts to input 60 Activation, then execute zero calibration. The steering angle sensor is widely used in vehicle dynamic stability control systems, with its stability and precision directly related to driving safety. Compared to the commonly used ABS systems in current vehicles, it not only includes all functions of ABS systems but also actively brakes when the vehicle loses stability, thereby controlling the vehicle's posture and ensuring driving safety to a certain extent.
Last time when my steering wheel warning light came on, the technician at the 4S store spent over ten minutes resetting the steering angle sensor using a diagnostic computer. He explained that this sensor monitors steering position, and if not reset properly, it could cause power steering failure or even trigger electronic stability system malfunctions. The reset process involves two steps: first, disconnect the battery negative terminal for 5 minutes to clear the system, then reconnect the power; next, start the engine and turn the steering wheel fully left and right three times while stationary. Procedures vary significantly between models - German cars often require specialized computers to reset matching values, while Japanese vehicles might just need button combinations. After resetting, remember to drive several kilometers to allow system adaptation, otherwise fault codes may reappear. It's recommended to consult the owner's manual or visit professional shops for this operation, as it involves electronic system safety.
