AUDIO SYSTEMDESCRIPTION1. RADIO WAVE BAND

The radio wave bands used in radio broadcasting are as follows:

LF: Low FrequencyMF: Medium FrequencyHF: High FrequencyVHF: Very High Frequency

2. SERVICE AREAThere are great differences in the size of the service area for AMand FM monaural. Sometimes FM stereo broadcasts cannot bereceived even through AM can be received in very clearly.Not only does FM stereo have the smallest service area, but italso picks up static and other types of interference (”noise”)easily.

3. RECEPTION PROBLEMSBesides the problem of static, there are also the problemscalled ”fading”, ”multipath” and ”fade out”. These problems arecaused not by electrical noise but by the nature of the radiowaves themselves.

(1) FadingBesides electrical interference, AM broadcasts arealso susceptible to other types of interference, es-pecially at night. This is because AM radio wavesbounce off the ionosphere at night. These radiowaves then interfere with the signals from the sametransmitter that reach the vehicle’s antenna directly.This type of interference is called ”fading”.

(2) MultipathOne type of interference caused by the bounce ofradio waves off of obstructions is called ”multipath”.Multipath occurs when a signal from the broadcasttransmitter antenna bounces off buildings andmountains and interferes with the signal that is re-ceived directly.

(3) Fade OutBecause FM radio waves are of higher frequenciesthan AM radio waves, they bounce off buildings,mountains, and other obstructions. For this reason,FM signals often seem to gradually disappear orfade away as the vehicle goes behind a building orother obstruction. This is called ”fade out”.

4. COMPACT DISC PLAYERCompact Disc Players use a laser beam pick-up to read the dig-ital signals recorded on the CD and reproduce analog signalsof the music, etc.HINT:Never attempt to disassemble or oil any part of the player unit.Do not insert any object other than a disc into the magazine.NOTICE:CD players use an invisible laser beam which could causehazardous radiation exposure. Be sure to operate the play-er correctly as instructed.

5. Tape Player/Head Cleaning:MAINTENANCE

(a) Raise the cassette door with your finger.Next, using a pencil or similar object, push in the guide.

(b) Using a cleaning pen or cotton applicator soaked in clean-er, clean the head surface, pinch rollers and capstans.

6. CD Player/Disc Cleaning:MAINTENANCE

If the disc gets dirty, clean the disc by wiping the surface fromthe center to outside in the radial directions with a soft cloth.NOTICE:Do not use a conventional record cleaner or anti-static pre-servative.

7. OUTLINE OF AVC-LAN(a) What is AVC-LAN?

AVC-LAN is the abbreviation, which stands for Audio Visual Communication-Local Area Network.This is a unified standard co-developed by 6 audio manufactures associated with Toyota Motor Corpo-ration.The Unified standard covers signals, such as audio signal, visual signal, signal for switch indicationand communication signal.

(b) ObjectivesRecently the car audio system has been rapidly developed and functions have been changed drasti-cally. The conventional system has been switched to the multi-media type such as a navigation sys-tem. At the same time the level of customers needs to audio system has been upgraded. This lies be-hind this standardization.The concrete objectives are explained below.(1) When products by different manufactures were combined together, there used to be a case that

malfunction occurred such as sound did not come out. This problem has been resolved by stan-dardization of signals.

(2) Various types of after market products have been able to add or replace freely.(3) Because of the above (2), each manufacture has become able to concentrate on developing

products in their strongest field. This has enabled many types of products provided inexpensive-ly.

(4) Conventionally, a new product developed by a manufacture could not be used due to a lack ofcompatibility with other manufactures products. Because of this new standard, users can enjoycompatible products provided for them timely.

(c) The above descriptions are the objectives to introduce AVC-LAN. By this standardization, develop-ment of new products will no longer cause systematic errors. Thus, this is very effective standard fora product in the future.

HINT: When +B short or GND short is detected in AVC-LAN circuit, communication stops. Accordingly the

audio system does not function normally. When audio system is not equipped with a navigation system, audio head unit is the master unit. (When

audio system is equipped with a navigation system, navigation ECU is the master unit.) The car audio system using AVC-LAN circuit has a diagnosis function. Each product has its own specified numbers called physical address. Numbers are also allotted to

each function in one product, which are called logical address.

BODY ELECTRICAL SYSTEMPRECAUTIONTake care to observe the following precautions when performing inspections or removal and replacementof body electrical related parts.1. HEADLIGHT SYSTEMHalogen bulbs have pressurized gas inside and require special handling. They can burst if scratched ordropped. Hold a bulb only by its plastic or metal case. Don’t touch the glass part of a bulb with bare hands.2. SRS (SUPPLEMENTAL RESTRAINT SYSTEM)The ECHO is equipped with an SRS (Supplemental Restraint System) such as the driver airbag and frontpassenger airbag. Failure to carry out service operation in the correct sequence could cause the SRS tounexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing (including re-moval or installation of parts, inspection or replacement), be sure to read the precautionary notices in theRS section.3. AUDIO SYSTEM If the negative (-) terminal cable is disconnected from the battery, the preset AM, FM 1 and FM 2 sta-

tions stored in memory are erased, so make sure to note the stations and reset them after the negative(-) terminal cable is reconnected to the battery.

If the negative (-) terminal cable is disconnected from the battery, the ”ANTI-THEFT SYSTEM” willoperate when the cable is reconnected, but the radio, tape player and CD player will not operate. Besure to input the correct ID number so that the radio, tape player and CD player can be operated again.

The area around the headlight is not deformed. The vehicle is parked on a level surface. Tire inflation pressure is the specified value. A driver is in the driver’s seat and the vehicle is in a state ready for driving (with a tank full). The vehicle has been bounced several times.

(b) Check the headlight aiming.(1) Prepare a thick white paper.(2) Stand the paper perpendicular to the ground at the position 9.84 ft away from the headlights.(3) Ensure that the center line of the vehicle and the paper face forms a 90-degree angle as shown

in the illustration.(4) Draw a horizontal line (H line) on the paper, showing where the headlights should strike.(5) Draw a vertical line (V line) to where the center line of the vehicle is to be.(6) Draw 2 vertical lines to where the both headlights should strike (V RH and V LH lines).(7) Draw a horizontal line (by connecting the both low beam center marks) to where the headlights

should strike (H RH and H LH lines).HINT:The H RH and H LH line is 0.4° below the horizontal line (H line) of the light axis.

(8) Start the engine.(9) Turn the headlights ON.(10) Check that the headlights properly strike the position shown in the illustration.(11) If not, adjust the lights in the vertical or horizontal direction.

HINT: As shown in the illustration, adjust each aim of the RH and LH lights. Since the horizontal direction is impossible to adjust, the value * of the ”Low Beam” aim is reference

value.(c) When adjusting it in the vertical direction:

NOTICE:When replacing the door control receiver and transmitter,registration of r ecognition code is necessary because theyare provided as single components.(a) Select which operation mode should be performed from

the following modes. Add mode Rewrite mode Prohibition mode Confirmation mode

HINT: The add mode is used to retain codes already registered

while you register new recognition codes. This mode isused when adding a transmitter. However, if the numberof registered codes exceeds 4 codes, previously regis-tered codes are correspondingly erased in order, startingfrom the first registered code.

The rewrite mode is used to erase all previously regis-tered codes and register only new recognition codes.

The prohibition mode is used to erase all registered codesand cancels the wireless door lock function. Use thismode when the transmitter is lost.

The confirmation mode is for confirming how many recog-nition codes are already registered before you registeradditional recognition codes.

(b) Follow the chart on the following pages to register thetransmitter recognition code at the wireless door lock con-trol receiver.
