HINT:
A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the radio and display receiver assembly*1 or navigation receiver assembly*2 with the connector connected.
If the result is not as specified, the rear television camera assembly may have a malfunction.
(e) Using an oscilloscope, check the waveform.
HINT:
A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the inner rear view assembly with the connector connected.
