b.

Measure the voltage of each terminal of the wire harness side connector.

Terminal No. (Symbol) Terminal Description Condition Specified Condition
O115-6 (CB+) - Body ground Power source Ignition switch ACC 5.5 to 7.05 V

If the result is not as specified, there may be a malfunction on the wire harness side.


c.

Reconnect the O115 rear television camera assembly connector.


d.

Measure the voltage and check for pulses at each terminal of the connector.

Terminal No. (Symbol) Terminal Description Condition Specified Condition
O115-3 (CV+) - O115-2 (CV-) Video signal Ignition switch ON
Reverse (R) selected
Camera lens not covered, displaying an image 		Pulse generation
(Refer to waveform 1)
Ignition switch ON
Reverse (R) selected
Camera lens covered, blacking out the screen 		Pulse generation
(Refer to waveform 2)
O115-5 (CGND) - Body ground Shield ground Always Below 1 V

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.


If the result is not as specified, the rear television camera assembly may be malfunctioning.

Reference (Oscilloscope waveform):

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.


i.

Waveform 1 (camera lens is not covered, displaying an image)

Item Content
Measurement terminal O115-3 (CV+) - O115-2 (CV-)
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 ACC.

·

Make sure that the rear camera is enabled in general settings.
