5. |
CHECK SIDE TELEVISION CAMERA ASSEMBLY RH (RCV+, RGND) |
(a) Remove the parking assist ECU with the connector still connected.
(b) Using an oscilloscope, check the waveform of the side television camera assembly RH.
HINT:
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 |
- |
- |
HINT:
- The video waveform changes according to the image sent by the side television camera assembly RH.
- The video waveform is constantly output when the power switch is on (ACC).
