Part name Description
AV CONTROL UNIT • Integrates HDD (hard disk dr
ive) allowing map data and music data to be
stored.
• It is the master unit of the MULTI AV system, and it is connected to each control unit by means of communication. It operates each system according to com-
munication signals from the AV control unit.
• The AV control unit includes the audio, hands-free phone, voice control, navi- gation, and vehicle information functions.
• It is connected to ECM and combination meter via CAN communication to ob-
tain necessary information for the vehicle information function.
• It inputs the automatic brightness ON/OFF signals that are required for the dis- play dimming control.
• It inputs the signals for driving status recognition (vehicle speed, reverse and
parking brake).

Regarding Wiring Diagram information, refer to
AV-116, "Wiring Diagram".
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-171, "Removal and Installation".
NO >> Replace AV control unit. Refer to AV-169, "
