WIRING DIAGRAM





INSPECTION PROCEDURE

PROCEDURE

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





(a) Disconnect the multi-display connector and radio receiver connector.





(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
2. INSPECT RADIO RECEIVER (OUTPUT SIGNAL)





(a) Reconnect the radio receiver connector.





(b) Measure the waveform according to the table below.
OK:





HINT: The waveform pattern may differ from that shown in the illustration due to differences in oscilloscope settings. A normal radio receiver operating condition can be determined if any waveform is output.
HINT: Oscilloscope wave
HINT: Terminal: J52-1 (NTSC) - Body ground
HINT: Setting: 200 mV/DIV. 10 micro s/DIV.
HINT: Condition: DVD display is on.

NG -- REPLACE RADIO RECEIVER
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
