DVD Image Signal Circuit between Radio Receiver and Multi-display: Procedure

1. Disconnect the radio receiver assembly connector.
2. Disconnect the display and navigation module display connector.
3. Measure the resistance according to the value(s) in the table below.
   STANDARD RESISTANCE
   
   

   Tester Connection	Condition	Specified Condition
   J65-8 (NTSC) - J52-9 (VV+)	Always	Below 1 Ω
   J65-22 (GND) - J52-20 (VV-)	Always	Below 1 Ω
   J65-8 (NTSC) - Body ground	Always	10 kΩ or higher
   J65-22 (GND) - Body ground	Always	10 kΩ or higher
   J65-7 (SLD) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Reconnect the radio receiver assembly connector.

   Item	Content
   Measurement terminal	J65-8 (NTSC) - Body ground
   Measurement setting	200 mV/DIV. 10 μs/DIV.
   Condition	DVD display is on

   NOTE:

   The video waveform changes according to the image output from the radio receiver assembly to the display and navigation module display, but the synchronization signal does not change.
