Monitor item Data monitor
Condition Display value
Steering torque Engine running

Steering wheel: Not steering

(There is no steering force) 		Approx. 0.0 Nm
Steering wheel: Right turn Negative value (Nm)
Steering wheel: Left turn Positive value (Nm)
Demanded motor current Engine running

Steering wheel: Not steering

(There is no steering force) 		Approx. 0 A
Steering wheel: Left or Right turn Displays consumption current of EPS motor
Assist level Engine running Not steering assist 99 %*1
EPS warning Engine running EPS system is normal No error
Not used Error1
EPS system malfunction Error2
Demanded assistance torque Engine running

Steering wheel: Not steering

(There is no steering force) 		Approx. 0.0 Nm
Steering wheel: Right turn Negative value (Nm)
Steering wheel: Left turn Positive value (Nm)
Measured motor current Engine running

Steering wheel: Not steering

(There is no steering force) 		Approx. 0 A
Steering wheel: Left or Right turn Displays consumption current of EPS motor*2

*1: Normally displays 99%. In case of an excessive stationary steering, the assist curvature gradually falls. However, it returns to 99% when left standing.

*2: Almost in accordance with the value of “Target motor current”. It is not a malfunction though these values are not accorded when steering quickly.

*3: It is not a malfunction, though it might not be corresponding just after ignition switch ON.
