Condition Engine switch on (IG) WAVEFORM 16 ECM Terminal Name Between NE+ and NE- Tester Range 2 V/DIV., 20 ms./DIV. Condition Idling with warm engine HINT: The wavelength becomes shorter as the engine speed increases. WAVEFORM 17 ECM Terminal Name CH1: Between VV1+ and VV1- CH2: Between VV2+ and VV2- Tester Range 5 V/DIV., 20 ms./DIV. Condition Idling HINT: The wavelength becomes shorter as the engine speed increases. WAVEFORM 18 ECM Terminal Name CH1: Between EV1+ and VV1- CH2: Between EV2+ and VV2- Tester Range 5 V/DIV., 20 ms./DIV. Condition Idling HINT: The wavelength becomes shorter as the engine speed increases. WAVEFORM 19 ECM Terminal Name Between RFC and E1 Tester Range 1 V/DIV., 20 ms./DIV. Condition Engine switch on (IG), A/C switch on (max cool) HINT: The duty ratio varies depending on the engine coolant temperature.Starter Signal Circuit
