L110 HYBRID VEHICLE CONTROL: HYBRID CONTROL SYSTEM: TERMINALS OF ECU

TERMINALS OF ECU





























NOTE: Do not measure voltage or waveform directly at the sealed side of the hybrid vehicle control ECU connectors. Doing so may damage the connectors because these connectors are waterproof.

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

(p) Waveform 16 (MG communication clock signal)










(q) Waveform 17 (MG communication request signal)










(r) Waveform 18 (communication signal from battery smart unit to HV control ECU)





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





(s) Waveform 19 (airbag deployment signal)










(t) Waveform 20 (READY signal)










(u) Waveform 21 (SL1 solenoid valve signal)










(v) Waveform 22 (A/C communication signal)





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





(w) Waveform 23 (SL2 solenoid valve signal)










(x) Waveform 24 (transmission revolution signal)





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













NOTE: Do not measure voltage or waveform directly at the sealed side of the inverter with converter assembly connectors. Doing so may damage the connectors because these connectors are waterproof.

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





(a) Waveform 1 (Motor resolver signal)





HINT: Pulse cycle A becomes shorter as the rotor speed increases.





(b) Waveform 2 (MG ECU communication request signal)










(c) Waveform 3 (Communication signal from MG ECU to HV control ECU)





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





(d) Waveform 4 (GI signal)





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





(e) Waveform 5 (Generator resolver signal)





HINT: Pulse cycle A becomes shorter as the rotor speed increases.





(f) Waveform 6 (Communication signal from HV control ECU to MG ECU)





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