Fig 1) Normal waveform of steering angle sensor with turning left after ENG "ON" : Output signal change ("LOW" → "HIGH") is detected first in ST1.

Fig 2) Normal waveform of steering angle sensor with turning right after ENG "ON" : Output signal change ("LOW" → "HIGH") is detected first in ST2.

Fig 3) Normal waveform of steering angle sensor being center position after ENG "ON" : Output signal change ("HIGH (approx 3.5V)" → "LOW") is detected when steering wheel is passing by on center position.

* "LOW": approx 1.5V, "HIGH": approx 3.5V.
