TERMINALS OF MG ECU





















*: Waveform cannot be measured because it is impossible to put the vehicle into the READY-on state with the inverter cover open.
2. Oscilloscope waveforms
HINT: Oscilloscope waveform samples are provided here for informational purposes. Noise and fluttering waveforms have been omitted.





(a) Waveform 1 (Rear Motor switch U signal)










(b) Waveform 2 (Rear Motor switch W signal)










(c) Waveform 3 (Rear Motor switch V signal)










(d) Waveform 4 (Generator switch U signal)










(e) Waveform 5 (Generator switch W signal)










(f) Waveform 6 (Generator switch V signal)










(g) Waveform 7 (Motor switch U signal)










(h) Waveform 8 (Motor switch W signal)










(i) Waveform 9 (Motor switch V signal)










(j) Waveform 10 (DC/DC converter voltage switch signal)










(k) Waveform 11 (communication signal from MG to HV)





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





(l) Waveform 12 (communication signal from HV to MG)





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





(m) Waveform 13 (MG communication request signal)










(n) Waveform 14 (MG communication clock signal)
