TERMINALS OF ECU
HINT: Since the inverter with converter assembly uses waterproof connectors, the voltage and waveforms 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 on the sealed side of the inverter with converter assembly connector. Doing so may damage the connector because the connector is waterproof. Oscilloscope waveforms HINT: Oscilloscope waveforms shown in the illustrations are examples for reference only. Noise, chattering, etc. are not shown. (a) Waveform 1 (CAN communication signal)
(b) Waveform 2 (camshaft position sensor signal)
HINT: The wavelength becomes shorter as the engine speed increases. (c) Waveform 3 (crankshaft position sensor signal)
HINT: The wavelength becomes shorter as the engine speed increases. (d) Waveform 4 (communication signal)
HINT: The waveform will vary depending on the content of the digital communication (digital signal). (e) Waveform 5 (motor resolver signal)
HINT: The width indicated by (A) becomes shorter as the rotor speed increases. (f) Waveform 6 (generator resolver signal)
HINT: The width indicated by (A) becomes shorter as the rotor speed increases. |
