Part 2
(p) Waveform 16 (VLO signal)
HINT
The cycle will vary depending on the specified voltage of the hybrid vehicle converter.
(q) Waveform 17 (oil pump motor signal)
(r) Waveform 18 (oil pump motor signal)
(s) Waveform 19 (MG communication clock signal)
(t) Waveform 20 (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).
(u) Waveform 21 (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).
(v) Waveform 22 (MG communication request signal)
(w) Waveform 23 (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).
(x) Waveform 24 (HV water pump signal)
(y) Waveform 25 (READY signal)
(z) Waveform 26 (vehicle speed signal)
HINT
The higher the vehicle speed, the shorter the cycle.
(aa) Waveform 27 (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.
