RGB AREA (YS) SIGNAL CIRCUIT
DescriptionINFOID:0000000003765910
Transmits the display area of RGB image displayed by AV control unit or NAVI control unit with RGB area (YS)
signal to display unit.
Diagnosis ProcedureINFOID:0000000003765911
1.CHECK CONTINUITY RGB AREA (YS) 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 terminal 9 and ground.
Is inspection result normal?
YES >> GO TO 2.
NO >> Repair harness or connector.
2.CHECK RGB SYNCHRONIZING 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 display unit.
NO >> Replace AV control unit.
