Is either resistance greater than 5 ohms? -> Yes INSTALL a new harness. For additional information, refer to the wiring diagrams.
-> No For signal output from the control panel tests, GO to Pinpoint Test G240121p6. . G240121t5 : CHECK THE SIGNAL TO THE RIGHT-HAND REAR SCREEN 1. Turn the ignition switch to the OFF position. 2. Make sure the video/audio tester is switched OFF. 3. Reconnect the intermediate connector, TL91. 4. Reconnect the audio video module electrical connector, TL87. 5. Disconnect the screen connector, VR01. 6. Turn the video/audio tester ON, and to the TEST position by holding in the TEST button while selecting PAL or NTSC. The blue and red LEDs will illuminate. 7. Turn the ignition switch to the ON position. 8. Using suitable adaptors, and an assistant if necessary, connect the red oscilloscope probe to VR01, pin 15 (RW). 9. Using suitable adaptors, and an assistant if necessary, connect the black oscilloscope probe to VR01, pin 09 (B). •
Is the waveform similar to the example in Waveforms in this section? -> Yes INSTALL a new rear screen, Video Display
-> No GO to Pinpoint Test G240121t6.
G240121t6 : CHECK THE SIGNAL TO THE RIGHT-HAND REAR SCREEN 1. Turn the ignition switch to the OFF position. 2. Make sure the video/audio tester is switched OFF. 3. Remove the seat back and disconnect the rear screen intermediate connector, VR02. 4. Turn the video/audio tester ON, and to the TEST position by holding in the TEST button while selecting PAL or NTSC. The blue and red LEDs will illuminate. 5. Turn the ignition switch to the ON position. 6. Using suitable adaptors, and an assistant if necessary, connect the red oscilloscope probe to VR02, pin 15 (RW). 7. Using suitable adaptors, and an assistant if necessary, connect the black oscilloscope probe to VR02, pin 09 (B). •
Is the waveform similar to the example in Waveforms in this section? -> Yes INSTALL a new harness between VR02 and VR01. Test the system for normal operation.
