VERTICAL SYNCHRONIZING (VP) SIGNAL CIRCUIT
Description
INFOID:0000000003765914
In composite image (AUX image, camera image), transmit the vertical synchronizing (VP) signal and horizon-
tal synchronizing (HP) signal from display unit to AV control unit so as to synchronize the RGB images dis-
played with AV control unit such as the image quality adjusting menu, etc.
Diagnosis Procedure
INFOID:0000000003765915
1.
CHECK CONTINUITY VERTICAL SYNCHRONIZING (VP) SIGNAL CIRCUIT
1.
Turn ignition switch OFF.
2.
Disconnect display unit connector and AV control unit connector.
3.
Check continuity between display unit harness connector and AV control unit harness connector.
4.
Check continuity between display unit harness connector and ground.
Is inspection result normal?
YES
>> GO TO 2.
NO
>> Repair harness or connector.
2.
CHECK VERTICAL SYNCHRONIZING (VP) SIGNAL
1.
Connect display unit connector and AV control unit connector.
2.
Turn ignition switch ON.
3.
Check signal between display unit harness connector terminal and ground using an oscilloscope.
Is inspection result normal?
YES
>> Replace AV control unit.
NO
>> Replace display unit.
