Display Signal Circuit between Multi-display and Radio Receiver

DESCRIPTION

This is the DVD display signal circuit from the radio receiver to the multi-display.

WIRING DIAGRAM

INSPECTION PROCEDURE

1. CHECK HARNESS AND CONNECTOR (RADIO RECEIVER - MULTI-DISPLAY)

1. Disconnect the multi-display connector J52 and radio receiver J62 connector.

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

2. INSPECT RADIO RECEIVER (OUTPUT SIGNAL)

1. Reconnect the radio receiver connector J62.

2. Measure the waveform according to the table below.

   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
