5. COMPACT DISC PLAYER
Compact Disc Players (hereinafter referred as CD) use a laser beam pick--up to read the digital signals
recorded on the CD and reproduce analog signals of 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 disc box.
NOTICE:
CD players use an invisible laser beam which could cause hazardous radiation exposure. Be sure
to operate the player correctly as instructed.
6. MAINTENANCE
(1) Tape player/magnet head cleaning:
1Raise the cassette door with your finger.
Next, using a pencil or similar object, push in
the guide.
2Using a cleaning pen or cotton applicator soaked
in cleaner, clean the magnet head surface, pinch
rollers and tape press wheel.
(2) 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 preservative.ExampleMagnet HeadTape Press WheelPinch Roller
2454. Trouble Identification
(1) Trouble Record (DTC storage)
When the circular diagnostic tests are involved in identification of a trouble, the SRS ECU (HAE2.5) will
store relevant codes, first/last diagnosis time and frequency of the trouble in EEPROM.
ySRS ECU (HAE2.5) can store up to 6 troubles, low voltage trouble as well as two crash records (front
and side).
yThe transmit of the DTCs are carried out in the way that the SRS ECU£¨HAE2.5£©via serial data
interface of the maintenance procedures assign the codes to the diagnostic detector.No. Trouble De scription Trouble shooting

259III. DIAGNOSIS OF CRASHED VEHICLEsWhether the SRS is deployed or not, the checking and maintenance of the crashed vehicle shall be carried
out according to the following procedures.
1. Check the diagnostic signal of ECU
(1) Connect the check connector of the Hi-DS T Scan Meter.
(2) Read out the diagnostic results from Hi-DS T Scan Meter.
2. Repair procedures
(1) When the SRS is deployed, the following parts shall be renewed.
1Passenger airbag assembly.
2ECU.
3Driver airbag assembly.
Check the following parts, if abnormal, replace with new ones.
1Clock spring.
2Steering wheel, steering column and steering lower shaft
component.
The installation status of driver airbag assembly in relation to steering wheel.
1Check and see if there is abnormal noise in the steering wheel, the action of the same is good,
or the clearance is normal.
2Check the union joint of the wire harness for damage and the terminal for distortion.
3. ECU
(1) Check the brackets of the ECU Case for recess, crack, distortion, etc.
(2) Check the union joint for damage and terminal for distortion.
(3) Check the installation status of he ECU brackets
1Check the hood for recess, crack, distortion, etc.
2Check the union joint for damage, terminal for distortion
and wire harness for seizure.
3Check the case of the gas generator for recess,
crack and distortion.NOTICE
Due to shock, when the battery power
supply is insufficient, the scan Meter
cannot communicate with ECU, the
instrument panel wire harness shall be
checked and maintained or external
power source shall be used.
