Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
System Outline: Notes
In the VGRS system, the steering gear ratio can be changed at will. Thus, the VGRS ECU operates the VGRS actuator in order to constantly realize an optimal gear ratio in accordance with the driving conditions of the vehicle. Thus, it attains a high level of maneuverability and stability between the low-and the high-speed driving ranges.
This system is controlled by the VGRS ECU, which operates the VGRS actuator that is mounted on the steering intermediate shaft. The operating angle of the actuator is thus added to the steering angle of the intermediate shaft in order to vary the turning angle of the front wheels in accordance with the vehicle speed.
