(8) Oil or water should not be put on the front seat outer belt and the front seat outer belt should be
cleaned with the appropriate detergents.
(i) AIRBAG SENSOR ASSEMBLY
(1) Never reuse the airbag sensor assembly involved in a collision where the SRS has deployed.
(2) The connectors to the airbag sensor assembly should be connected or disconnected with the
sensor mounted on the floor. If the connectors are connected or disconnected while the airbag
sensor assembly is not mounted to the floor, it could cause an undesired ignition of the supple-
mental restraint system.
(3) Work must be started after 90 seconds from the time the ignition switch is turned to the ºLOCKº
position and the negative (±) terminal cable is disconnected from the battery, even if only loosen-
ing the set bolts of the airbag sensor assembly.
(j) WIRE HARNESS AND CONNECTOR
(1) The SRS wire harness is integrated with the instrument panel wire harness assembly. All connec-
tors in the system are a standard yellow color. If the SRS wire harness becomes disconnected
or the connector becomes broken due to an accident, etc., repair or replace it.
3. ELECTRONIC CONTROL
(a) REMOVAL AND INSTALLATION OF BATTERY TERMI-
NAL
(1) Before performing electronic work, disconnect the
battery negative (±) terminal cable beforehand in
order to prevent it from shorting and burning out.
(2) When disconnecting and installing the terminal
cable, turn the ignition switch and lighting switch
OFF, and loosen the terminal nut completely. Per-
form these operations without twisting or prying the
terminal.
(3) When the battery terminal cable is removed, the
memories of the clock, radio, DTCs, etc. are erased.
So before removing it, check them and make a note
of their settings.
(4) When the battery negative (±) terminal cable is dis-
connected, memories of various systems are
erased. Therefore, refer to the PRE±CHECK for
each system to make sure whether or not the sys-
tem needs to be initialized after the battery negative

2. IDENTIFICATION OF NOISE SOURCE
(a) Identify the condition under which the noise occurs, and
check the noise filter on the related part.
Condition in which noise occursNoise Source
Depressing the acceleration pedal increases noise, and stopping the engine
erases the noise immediately.Generator
Noise occurs during the A/C or the heater operation.Blower motor
Rapid acceleration while driving on the unpaved road or after the IG switch is
turned ON makes noise.Fuel pump
Pressing and then releasing the horn switch, and keeping pressing the horn
switch makes unusual noise.Horn
Stopping the engine erases small noise that has been heard.Ignition
Noise occurs synchronously with the turn signal flash.Flasher
Noise occurs during the window washer operation.Washer
Noise occurs during the engine running, and it continues after the engine
stops.Engine coolant temperature sensor
Noise occurs during the wiper operation.Wiper
Noise occurs when the brake pedal is depressed.Stop light switch
Others.Static electricity stored on the vehicle
(b) Reference:

Make sure first that there is no noise from outside.
Failing to do so makes the noise source detection
difficult and leads to misunderstanding.

The noise should be removed in descending order
of loudness.

Setting the radio untuned makes noise noticeable,
making the recognition of the phenomenon easier.

6. MAINTENANCE
Tape Player / Head Cleaning:
(a) Raise the slot cover with your finger.
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.
7. MAINTENANCE

the center to outside in the radial directions with a soft cloth.
NOTICE:
Do not use a conventional record cleaner or anti±static pre-
servative.
8. COMMUNICATION SYSTEM
(a) Components in the audio system communicate each other though AVC±LAN. (Radio receiver func-
tion)
(b) The master component of AVC±LAN is the radio receiver assy with a resistance (60 ± 80
), which
is necessary for communication.
(c) When short circuit or open circuit occurs in the AVC±LAN circuit, the audio system does not operate
normally due to the communication cutoff.
9. DIAGNOSIS FUNCTION
(a) The audio system has diagnosis function (The diagnosis result is displayed on the LCD of the radio
receiver assy). (Radio receiver function)
(b) The component code (physical address), or three±digit number (in hexadecimal) is set for each com-
ponent comprising AVC±LAN.
(c) The logical address, or two±digit number (in hexadecimal) is set for each function and component unit
in each component.
