DescriptionINFOID:0000000001696111
Transmit the image displayed with AV control unit with RGB signal to the display unit.
Diagnosis ProcedureINFOID:0000000001696112
1.CHECK CONTINUITY RGB (B : BLUE) SIGNAL CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect display unit connector M93 and AV control unit con- nector M43.
3. Check continuity between display unit harness connector M93 (A) terminal 18 and AV control unit harness connector M43 (B)
terminal 23.
4. Check continuity between display unit harness connector M93 (A) terminal 18 and ground.
Are continuity results as specified?
YES >> GO TO 2
NO >> Repair harness or connector.
2.CHECK RGB (B: BLUE) SIGNAL
1. Connect display unit connector M93 and AV control unit connec-
tor M43.
2. Turn ignition switch ON.
3. Check signal between display unit harness connector M93 ter-
minal 18 and ground.
Are voltage readings as specified?
YES >> Replace display unit. Refer to AV-166, "Removal and Installation".
NO >> Replace AV control unit. Refer to AV-164, "
Removal and Installation".
