L110F HYBRID VEHICLE CONTROL: HYBRID CONTROL SYSTEM: TERMINALS OF ECU

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)

(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 (immobilizer communication signal)

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

(m) Waveform 13 (CAN communication signal)

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

(n) Waveform 14 (CAN communication signal)

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

(o) Waveform 15 (CAN communication signal)

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