    1. A01JARTE01

      Waveform 1 (Rotation angle sensor signal)

      Item Contents
      Terminal

      A23-17 (RA) - A23-19 (E2)

      A23-8 (RB) - A23-19 (E2)
      Equipment setting 2 V/DIV., 100 msec./DIV.
      Condition

      Power switch on (IG)

      Changing from park (P) to neutral (N), or neutral (N) to park (P).

      Tech Tips


      • When changing from park (P) to neutral (N), or neutral (N) to park (P) with the power switch on (IG), a waveform will be generated for up to 0.5 seconds.

      • The waveform shown is for reference only.
