Rear View Monitor System (w/o Navigation System)

PARK ASSIST / MONITORING: REAR VIEW MONITOR SYSTEM: TERMINALS OF ECU

1. REAR TELEVISION CAMERA ASSEMBLY

(a) Disconnect the V8 connector from the rear television camera assembly.





(b) Measure the voltage of each terminal of the wire harness side connector.





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

(c) Reconnect the V8 connector to the rear television camera assembly.

(d) Check for pulses between each terminal of the connector.





HINT
A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the navigation computer sub-assembly*1 or inner rear view mirror assembly*2 with the connector connected.

* *1: w/ Navigation System (for HDD)
* *2: w/o Navigation System

If the result is not as specified, the camera may have a malfunction.

(e) Reference (Oscilloscope waveform):

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





HINT
The video waveform changes according to the image sent by the television camera assembly.

(2) Waveform 2 (camera lens is covered, blacking out the screen)





HINT
The video waveform changes according to the image sent by the rear television camera assembly.
