This makes it possible to connect a cellular phone (Bluetooth capable phone*) to the multi-display (Bluetooth system is built-in), and use a handsfree function with the cellular phone in a pocket or bag. As a result, it is not necessary to use a connector for the cellular phone. HINT: *: The communication performance of Bluetooth may vary depending on the Bluetooth version, obstructions or radio wave conditions between communication devices, electromagnetic radiation, communication device sensitivity, or antenna capacity. AV AV–10 AUDIO / VISUAL – AUDIO AND VISUAL SYSTEM Multi-display (Built-in Bluetooth receiver antenna) Cellular Tower AV Cellular Phone (Bluetooth Type) I100033E09 4. AVC-LAN DESCRIPTION (a) What is AVC-LAN? Example Radio Receiver (Resistor 60 to 80 Ω) AVC-LAN Stereo Component Amplifier I100319E10 AVC-LAN, an abbreviation for "Audio Visual Communication Local Area Network", is a united standard developed by the manufacturers in affiliation with Toyota Motor Corporation. This standard pertains to audio and visual signals as well as switch and communication signals. AUDIO / VISUAL – AUDIO AND VISUAL SYSTEM 5. 6. AV–11 (b) Purpose: Recently, car audio systems have rapidly developed and the functions have vastly changed. The conventional car audio system is being integrated with multimedia interfaces similar to those in navigation systems. At the same time, customers are demanding higher quality from their audio systems. This is an overview of the standardization background. The specific purposes are as follows: (1) To solve sound problems, etc. caused by using components of different manufacturers through signal standardization. (2) To allow each manufacturer to concentrate on developing products they do best. From this, reasonably priced products can be produced. HINT: • If a short to +B or short to ground is detected in the AVC-LAN circuit, communication is interrupted and the audio system will stop functioning. • If an audio system is equipped with a navigation system, the multi-display unit acts as the master unit. If the navigation system is not equipped, the audio head unit acts as the master unit instead. If the radio and navigation assembly is equipped, it is the master unit. • The radio receiver contains a resistor that is necessary to enable communication on the different AVC-LAN circuits. • The car audio system with an AVC-LAN circuit has a diagnostic function. • Each component has a specified number (3digit) called a physical address. Each function has a number (2-digit) called a logical address. COMMUNICATION SYSTEM OUTLINE (a) Components of the audio system communicate with each other via the AVC-LAN. (b) The master component of the AVC-LAN is a radio receiver with a 60 to 80 Ω resistor. This is essential for communication. (c) If a short circuit or open circuit occurs in the AVCLAN circuit, communication is interrupted and the audio system will stop functioning. DIAGNOSTIC FUNCTION OUTLINE (a) The audio system has a diagnostic function (the result is indicated on the master unit). (b) A 3-digit hexadecimal component code (physical address) is allocated to each component on the AVC-LAN. Using this code, the component in the diagnostic function can be displayed.

(b) Delete the DTCs. (c) Recheck by simulating the operation indicated by the DTC. HINT: • If the system cannot enter the diagnosis mode, inspect each AVC-LAN communication signal and repair or replace the problem parts. • Even if the malfunction symptom is not confirmed, check the DTCs. This is because the system stores past DTCs. • Check and clear past DTCs. Then check for DTCs.

Frequency 300 kHz 30 kHz Designation RADIO DESCRIPTION (a) Radio frequency band (1) Radio broadcasts use the radio frequency bands shown in the table below. LF MF Modulation HF VHF FM Amplitude modulation MF: Medium Frequency 300 MHz 30 MHz AM Radio Wave LF: Low Frequency 30 MHz HF: High Frequency Frequency modulation VHF: Very High Frequency E108734E01 (b) Service area (1) The service areas of AM and FM broadcasts are vastly different. Sometimes an AM broadcast can be received very clearly but an FM stereo cannot. FM stereo has the smallest service area, and is prone to pick up static and other types of interference such as noise. (c) Radio reception problems HINT: In addition to static, other problems such as "phasing", "multipath", and "fade out" exist. These problems are not caused by electrical noise, but by the radio signal propagation method itself. FM (Stereo) FM (Monaural) AM E108735E01 Phasing Ionosphere I100011E02 (1) Phasing AM broadcasts are susceptible to electrical interference and another kind of interference called phasing. Occurring only at night, phasing is the interference created when a vehicle receives 2 radio wave signals from the same transmitter. One signal is reflected off the ionosphere and the other signal is received directly from the transmitter. AV AV–16 AUDIO / VISUAL – AUDIO AND VISUAL SYSTEM (2) Multipath Multipath is a type of interference created when a vehicle receives 2 radio wave signals from the same transmitter. One signal is reflected off buildings or mountains and the other signal is received directly from the transmitter. Multipath I100012E02 (3) Fade out Fade out is caused by objects (buildings, mountains, and other such large obstacles) that deflect away part of a signal, resulting in a weaker signal when the object is between the transmitter and vehicle. High frequency radio waves, such as FM broadcasts, are easily deflected by obstructions. Low frequency radio waves, such as AM broadcasts, are much more difficult to deflect. (d) Noise problem Technicians must have a clear understanding about each customer's noise complaint. Use the following table to diagnose noise problems. Fade Out I100013E02 AV Radio Frequency Noise Occurrence Condition Presumable Cause AM Noise occurs in a specified area Foreign noise AM Noise occurs when listening to an intermittent broadcast Same program transmitted from multiple towers can cause noise where the signals overlap AM Noise occurs only at night Music beats from a distant broadcast Noise occurs while driving in a specified area Multipath or phasing noise resulting from a change in FM frequency FM HINT: If the noise does not match the examples above, refer to the descriptions about phasing and multipath.
