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 (HV battery blower fan operation signal)

(k) Waveform 11 (immobilizer communication signal)

(l) Waveform 12 (CAN communication signal)

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

HINT: The cycle will vary depending on the specified voltage of the hybrid vehicle converter.

(p) Waveform 16 (oil pump motor signal)

(q) Waveform 17 (oil pump motor signal)

(r) Waveform 18 (MG communication clock signal)

(s) Waveform 19 (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).

(t) Waveform 20 (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).

(u) Waveform 21 (MG communication request signal)

(v) Waveform 22 (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).

(w) Waveform 23 (HV water pump signal)

(x) Waveform 24 (READY signal)

(y) Waveform 25 (vehicle speed signal)

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

(z) Waveform 26 (airbag deployment signal)

NOTICE:
Do not measure the voltage or waveform directly at the sealed side of the inverter with converter assembly connector. Doing so may damage the connector because the connector is waterproof.
