System Description

VGRS SYSTEM DESCRIPTION

The VGRS (Variable Gear Ratio Steering) system controls the steering angle in accordance with the vehicle speed. The system is controlled by the VGRS ECU which operates the VGRS actuator mounted on the steering intermediate shaft. The operating angle of the actuator is 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.

When the VGRS system is operating normally, the steering wheel can be turned approximately 2.4 turns from lock to lock, with the engine running and the vehicle stopped.

When the system detects a fault, the VGRS ECU illuminates the VGRS warning light to inform the driver that the system is not operating.

CAUTION: There may be conditions that will cause the steering wheel to be off center.
