HINT:

Beep sound is emitted once when the DTC memory is
completely cleared.

When the DTC memory is cleared, only the component
code (physical address) is displayed for the target compo-
nent.

To check the DTC, press the preset switch º1º and perform
the service check again.
(g) Clearance of all the DTC memory (when clearing all the
memory of the DTC detected in the past)
(1) Start the diagnosis mode after repairing the trouble
area.
(2) Press the preset switch º5º for 2 seconds or more.
(ºCLRº is displayed at this time.)
HINT:

Beep sound is given once when the DTC memory is com-
pletely cleared.

When the DTCs memory for all the device is cleared, only
the component codes (physical address) are displayed.
(3) Press the preset switch º1º to perform the service
check again, and check that no DTCs are displayed
for all the component codes (physical address).

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
CD Player / Disc Cleaning:
If the disc gets dirty, clean the disc by wiping the surface from
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.

SOURCE VOLTAGE DROP
CIRCUIT DESCRIPTION
The SRS is equipped with a voltage±increase circuit (DC±DC converter) in the airbag sensor assy center
in case the source voltage drops.
When the battery voltage drops, the voltage±increase circuit (DC±DC converter) functions to increase the
voltage of the SRS to normal voltage.
A malfunction in this circuit is displayed by different form from the other code. The source voltage drop is
indicated when the SRS warning light comes on without showing any DTCs.
Malfunction in this circuit is not recorded in the airbag sensor assy center. The SRS warning light automatical-
ly goes off when the source voltage returns to normal.
DTC No.Diagnosis

5CHECK KNEE AIRBAG SQUIB CIRCUIT(SHORT)
(a)Release the activation prevention mechanism built in the
connector ºBº (See page 05±1184).
(b)Measure the resistance between DK+ and DK± of the connector ºEº.
OK:
Resistance 1 M
or Higher
NGGo to step 17
OK
6CHECK AIR BAG SENSOR ASSY CENTER
(a)Connect the connectors to the airbag sensor assy center and the instrument panel airbag assy.
