Using an oscilloscope, check the waveform of the side television camera assembly LH.
A waterproof connector is used for the side television camera assembly LH. Therefore, inspect the waveform at the parking assist ECU with the connector connected.
| *a | Component with harness connected
(Parking Assist ECU) |
*b | Waveform 1 (camera lens not covered, displaying an image) |
| *c | Waveform 2 (camera lens covered, blacking out the screen) | *d | Synchronization Signal |
| *e | Video Waveform | - | - |
The video waveform changes according to the image sent by the side television camera assembly LH.
The video waveform is constantly output when the engine switch is on (ACC).
