CHECK SIDE TELEVISION CAMERA ASSEMBLY RH (RCV+, RGND)
Remove the parking assist ECU with the connector still connected.
Using an oscilloscope, check the waveform of the side television camera assembly RH.
Tech Tips
A waterproof connector is used for the side television camera assembly RH. 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 | - | - |
Tech Tips
The video waveform changes according to the image sent by the side television camera assembly RH.
The video waveform is constantly output when the engine switch is on (ACC).
