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

1. Disconnect the L113 radio receiver assembly connector.
2. Disconnect the L114 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
   L113-8 (NTSC) - L114-9 (VV+)	Always	Below 1 Ω
   L113-22 (GND) - L114-20 (VV-)	Always	Below 1 Ω
   L113-8 (NTSC) - Body ground	Always	10 kΩ or higher
   L113-22 (GND) - Body ground	Always	10 kΩ or higher
   L113-7 (SLD) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Reconnect the L113 radio receiver assembly connector.

2. Measure the waveform according to the table below.

   OK

   Tester Connection	Condition	Specified Condition
   L113-8 (NTSC) - Body ground	Radio receiver is playing, image is being produced	Waveform synchronized with image is output

   NOTE:

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