*1: Almost in accordance with the value of MOTOR SIG. It is not a malfunction though these values are not accorded when steering quickly.

⁽¹⁾	Normally displays 100%. In case of an excessive stationary steering, the assist curvature gradually falls. However, it returns to 100% when left standing.

⁽²⁾	It is not a malfunction, though it might not be corresponding just after ignition switch in turned ON.
