What Causes Steering Wheel Stiffness at High Speeds?
1 Answers
High-speed steering wheel stiffness may result from the following causes: 1. Input sensor failure, such as a malfunctioning optical grating angle measurement sensor, preventing the ECU from properly obtaining user control parameters. 2. ECU malfunction: Computational errors in the ECU itself may lead to vehicle control actions that contradict the driver's intentions. 3. Improper driving: Prolonged driving with an unbalanced vehicle body may cause deviations in the yaw angle sensor position. 4. Solutions: Minor steering wheel stiffness can sometimes be resolved by adjusting the steering wheel up and down before returning it to its original position. Alternatively, turning the steering wheel lock-to-lock several times while stationary may eliminate the stiffness. If these methods prove ineffective, it is advisable to promptly visit an authorized dealership for inspection and resolution.
