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)

(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 ECU to hybrid vehicle control ECU)

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

(l) Waveform 12 (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).

(m) Waveform 13 (MG ECU communication request signal)

(n) Waveform 14 (MG ECU communication clock signal)

(o) Waveform 15 (rear motor resolver signal)

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

(p) Waveform 16 (generator resolver signal)

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

(q) Waveform 17 (motor resolver signal)

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