    A111593E02

  1. WAVEFORM 1

    1. Vehicle speed signal
      Power Management Control ECU Terminal Name
      		Between H3-14 (SPDI) and H3-6 (E1)
      Tester Range
      		5 V/DIV., 20 ms./DIV.
      Condition
      		Driving at 20 km/h (12 mph)

      HINT:
      1. The wavelength becomes shorter as the vehicle speed increases.
      2. Depending on the vehicle, the output waveform voltage may rise to 12 V if influenced by optionally installed systems.



    2. A194184E07

  2. WAVEFORM 2

    1. CAN communication signal
      Power Management Control ECU Terminal Name
      		Between H4-24 (CA1L) and H3-6 (E1)
      Tester Range
      		1 V/DIV., 10 μsec./DIV.
      Condition
      		Power switch on (IG)

      HINT:
      The waveform varies depending on the CAN communication signal.



    3. A194183E02

  3. WAVEFORM 3

    1. CAN communication signal
      Power Management Control ECU Terminal Name
      		Between H4-25 (CA1H) and H3-6 (E1)
      Tester Range
      		1 V/DIV., 10 μsec./DIV.
      Condition
      		Power switch on (IG)

      HINT:
      The waveform varies depending on the CAN communication signal.
