Measuring condition:
NOTE:
- Perform measurement after warming up the engine.
- For measurement of the waveform of the crankshaft position sensor, we recommend using the DST-i oscilloscope function or a general oscilloscope.
- Place the gear shift lever in the neutral position.
- Turn the A/C to OFF.
- Turn all the accessory switches to OFF.
- Waveforms vary depending on a measurement environment and vehicle condition.
