1. Oscilloscope waveforms

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

(a) Waveform 1 (DC/DC operation monitor / voltage change signal)

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

(b) Waveform 2 (Inverter water pump assembly signal)

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

(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 (HV battery blower fan operation signal)

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

(f) Waveform 6 (MG communication clock signal)

(g) Waveform 7 (P position signal)

(h) Waveform 8 (communication signal from power management control ECU (HV CPU) to MG ECU)

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

(i) Waveform 9 (communication signal from MG ECU to power management control ECU (HV CPU))

HINT

(j) Waveform 10 (MG ECU communication request signal)

(k) Waveform 11 (system main relay operation signal)

(l) Waveform 12 (vehicle speed signal)

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

(m) Waveform 13 (airbag deployment signal)

(n) Waveform 14 (communication signal from battery smart unit to power management control ECU (HV CPU))

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

(o) Waveform 15 (CAN communication signal)

HINT

(p) Waveform 16 (immobiliser communication signal)

(q) Waveform 17 (CAN communication signal)

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

(r) Waveform 18 (CAN communication signal)

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

HINT
Since the inverter with converter assembly uses waterproof connectors, the voltage and waveform cannot be inspected directly. Standard voltage readings and waveforms are indicated for reference only.

Inverter with converter assembly

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.
