TERMINALS OF HV CONTROL ECU

























1. Oscilloscope waveforms
HINT: Oscilloscope waveform samples are provided here for informational purposes. Noise and fluttering waveforms have been omitted.





(a) Waveform 1 (power meter signal)










(b) Waveform 2 (airbag deployment signal)










(c) Waveform 3 (HV water pump signal)










(d) Waveform 4 (vehicle speed signal)





HINT: The higher the vehicle speed, the shorter the cycle and higher the voltage.





(e) Waveform 5 (immobilizer communication signal)










(f) Waveform 6 (system main relay operation signal)










(g) Waveform 7 (HV battery blower fan operation signal)










(h) Waveform 8 (Communication signal from battery to HV)





HINT: The waveform varies depending on the contents of communication.





(i) Waveform 9 (CAN communication signal)





HINT: The waveform varies depending on the contents of communication.





(j) Waveform 10 (Oil pump signal)










(k) Waveform 11 (radiator fan operation signal)










(l) Waveform 12 (GO signal)





HINT: The pulse cycle becomes shorter as the engine speed increases.





(m) Waveform 13 (Crankshaft position signal)





HINT: The pulse cycle becomes shorter as the engine speed increases.





(n) Waveform 14 (engine speed signal)





HINT: The pulse cycle becomes shorter as the engine speed increases.





(o) Waveform 15 (communication signal from HV to MG)





HINT: The waveform varies depending on the contents of communication.





(p) Waveform 16 (MG communication clock signal)










(q) Waveform 17 (MG communication request signal)










(r) Waveform 18 (communication signal from MG to HV)





HINT: The waveform varies depending on the contents of communication.





(s) Waveform 19 (A/C communication signal)





HINT: The waveform varies depending on the contents of communication.





HINT: Connectors A, B, and C are wired inside the w/ converter inverter assembly and usually not inspected. Terminal arrangement and measured values are provided as reference.
