| Waveform is similar to that shown in the illustration. |
| Item | Content |
|---|---|
| Measurement terminal | H97-18 (V+) - H97-12 (GND1) |
| Measurement setting | 200 mV/DIV., 50 μs./DIV. |
| Condition | Power switch on (IG), shift receiver in R |
Tech Tips
The video waveform changes according to the image sent by the rear television camera assembly.
The video waveform is constantly output when the power switch is on (ACC).
| *a | Waveform 1 (camera lens is not covered, displaying an image) |
| *b | Waveform 2 (camera lens is covered, blacking out the screen) |
| *c | Synchronization Signal |
| *d | Video Waveform |
