1. Oscilloscope waveforms

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

(a) Waveform 1 (SL1 solenoid valve signal)









(b) Waveform 2 (system main relay operation signal)









(c) Waveform 3 (SL2 solenoid valve signal)









(d) Waveform 4 (A/C communication signal)









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

(e) Waveform 5 (transmission revolution signal)









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

(f) Waveform 6 (CAN communication signal)









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

(g) Waveform 7 (NEI signal)









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

(h) Waveform 8 (GI signal)









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

(i) Waveform 9 (CAN communication signal)









(j) Waveform 10 (No. 2 HV battery blower fan operation signal)









(k) Waveform 11 (immobiliser communication signal)









(l) Waveform 12 (No. 1 HV battery blower fan operation signal)









(m) Waveform 13 (CAN communication signal)
