WIRING DIAGRAM

INSPECTION PROCEDURE

1 CHECK HARNESS AND CONNECTOR (RADIO AND NAVIGATION ASSEMBLY - TELEVISION DISPLAY ASSEMBLY)

1. 1
   Disconnect the radio and navigation assembly connector R16 and television display assembly connector T14.
2. 2
   Measure the resistance according to the value(s) in the table below.

Standard resistance

2 INSPECT TELEVISION DISPLAY ASSEMBLY

1. 1
   Reconnect the television display assembly connector R16.
2. 2
   Measure the waveform according to the table below.

OK

HINT: The waveform pattern may differ from that shown in the illustration below due to differences in oscilloscope setting. A normal television display assembly operating condition can be determined if any waveform is output.
