L110 HYBRID VEHICLE CONTROL: HYBRID CONTROL SYSTEM: TERMINALS OF ECU

























NOTICE:
Do not measure voltage or waveform directly at the sealed side of the hybrid vehicle control ECU connectors. Doing so may damage the connectors because these connectors are waterproof.

1. Oscilloscope waveforms

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

(e) Waveform 5 (CAN communication signal)









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

(f) Waveform 6 (CAN communication signal)









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

(g) Waveform 7 (GI signal)









HINT
