Using an oscilloscope, check the waveform of the rear television camera assembly.

HINT:

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.


OK:

Waveform is similar to that shown in the illustration.


Item Content
Measurement terminal I209-28 (V+) - I209-29 (V-)
Measurement setting 200 mV/DIV., 50 μs./DIV.
Condition Ignition switch ON, reverse (R) selected

HINT:
·

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.
