   CHECK FRONT PASSENGER SIDE OUTER REAR VIEW MIRROR ASSEMBLY

   
   
   1. 

      Measure the waveform of the front passenger side television camera assembly using an oscilloscope.

      Table 6. Text in Illustration

      *a	Component with harness connected (Parking Assist ECU)	*b	Waveform A
      *c	Waveform B	*d	Synchronized Signal
      *e	Video Waveform	-	-

      Tip:
      

      • A waterproof connector is used for the side television camera assembly. Therefore, inspect the waveform at the navigation receiver assembly*1 or radio and display receiver assembly*2 with the connector connected.

      • 
        

        • *1: for Navigation Receiver Type

        • *2: for Radio and Display Type

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