Inspection Using An Oscilloscope (Reference)
Steering angle (steering angle signal 1 and 2)
•DSC HU/CM terminal:
Steering angle signal 2: W (+) — R (-)
Steering angle signal 1: X (+) — R (-)
•Oscilloscope setting:
1 V/DIV (Y), 25 ms/DIV (X), DC range
•Vehicle condition: Rotating steering wheel at one
revolution per second
Note
•As steering wheel rotation speed increases,
period of wave shortens.
•As for shape of steering angle signals 1 and
2, the phase is different.
Wheel speed
•DSC HU/CM terminal:
RF: M (+) — I (-)
RR: K (+) — H (-)
LF: F (+) — J (-)
LR: Q (+) — N (-)
•Oscilloscope setting:
1 V/DIV (Y), 2 ms/DIV (X), AC range
•Vehicle condition: Driving 30 km/h (18.6 mph)
Note
•As vehicle speed increases, period of wave
shortens.
•If there is malfunctioning in the sensor rotor,
wave profile warps.
