Using an oscilloscope, check the waveform of the rear television camera assembly.
A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the radio and display receiver assembly with the connector connected.
Waveform is similar to that shown in the illustration.

| Measurement terminal | E139-14 (V+) - E139-28 (V-) |
| Measurement setting | 200 mV/DIV., 50 μs./DIV. |
| Condition | Ignition switch ON, reverse (R) selected |
The video waveform changes according to the image sent by the rear television camera assembly.
The video waveform is constantly output when the ignition switch is turned to ACC.
Make sure that the rear camera is enabled in general settings.
