2. Measure the resistance according to the value(s) in the table below.

   Standard resistance

   Tester Connection	Condition	Specified Condition
   GND - SGD1	Always	Below 1 Ω
   NTSC - NTSC	Always	Below 1 Ω
   SLD - SGND	Always	Below 1 Ω
   NTSC - Body ground	Always	10 kΩ or higher
   GND - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Reconnect the radio receiver connector E72.

   OK

   Tester Connection	Condition	Specified Condition
   NTSC - Body ground	DVD display is ON	A waveform synchronized with display signals is output

   HINT: 

   The waveform pattern may differ from that shown in the illustration below due to differences in oscilloscope settings. A normal radio receiver operating condition can be determined if any waveform is output.

   Oscilloscope wave

   Terminal: NTSC - Body ground

   Setting: 200 mV/DIV. 10 μs/DIV.

   Condition: DVD display is on.

NG → REPLACE RADIO RECEIVER 

OK → PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
