TERMINALS OF ECU

1. Oscilloscope waveforms

HINT: In the oscilloscope waveform samples, which are provided here for informational purposes. Noise and fluttering waveforms have been omitted.

Waveform 1:

2. Waveform 1

HINT: The waveform varies depending on the contents of communication.

Waveform 2:

3. Waveform 2

HINT: The waveform varies depending on the contents of communication.

Waveform 3:

4. Waveform 3

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

Waveform 4:

5. Waveform 4

Waveform 5:

6. Waveform 5

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

Waveform 6:

7. Waveform 6

*1: 1 frame

*2: 500 ms

HINT: The waveform on the left is repeated when the airbag system is normal.

Waveform 7:

8. Waveform 7

*1: 1 frame

*2: 40 ms

*3: 60 ms

HINT: The waveform on the left is repeated when the airbag system is abnormal.

Waveform 8:

9. Waveform 8

*1: 1 frame

*2: 20 ms

*3: 140 ms

*4: 100 ms

*5: 60 ms

HINT: When the airbag system is deployed, after 1 frame of transmission indicating a normal condition is completed, the waveform on the left is repeated for 50 frames. After that, normal transmission returns.
