TERMINALS OF HYBRID VEHICLE 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 activation signal)










(c) Waveform 3 (system main relay operation signal)










(d) Waveform 4 (READY control signal)










(e) Waveform 5 (HV water pump signal)










(f) Waveform 6 (vehicle speed signal)





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





(g) Waveform 7 (immobilizer communication signal)










(h) Waveform 8 (HV battery blower fan operation signal)





HINT: The duty ratio varies depending on the cooling fun mode.





(i) Waveform 9 (communication signal from battery smart unit to hybrid vehicle control ECU)





HINT: The waveform will vary depending on the content of the digital communication (digital signal).





(j) Waveform 10 (CAN communication signal)





HINT: The waveform will vary depending on the content of the digital communication (digital signal).





(k) Waveform 11 (oil pump signal)










(l) Waveform 12 (radiator fan operation signal)










(m) Waveform 13 (GO signal)





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





(n) Waveform 14 (crankshaft position signal)





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





(o) Waveform 15 (engine speed signal)





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





(p) Waveform 16 (communication signal from hybrid vehicle control ECU to MG ECU)





HINT: The waveform will vary depending on the content of the digital communication (digital signal).





(q) Waveform 17 (MG ECU communication clock signal)










(r) Waveform 18 (MG ECU communication request signal)










(s) Waveform 19 (communication signal from MG ECU to hybrid vehicle control ECU)





HINT: The waveform will vary depending on the content of the digital communication (digital signal).





(t) Waveform 20 (A/C communication signal)





HINT: The waveform will vary depending on the content of the digital communication (digital signal).





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