NOTE:
  • After engine is warmed up, attach the check board for measurement.
  • Set the select lever in "P" range or "N" range, or the shift lever in neutral.
  • Turn the A/C to OFF.
  • Turn all the accessory switches to OFF.
  • Waveforms vary depending on a measurement environment and vehicle condition.
  • Oscilloscope waveform illustrated here is an example for reference. Noise and chattering in waveform are omitted.
