Removal & Installation Procedure
preceding work : removal of steering wheel
1. Turn the ignition switch to “OFF” position and disconnect
the battery negative cable. Start the procedure after waiting
over 3oseconds.
2. Unscrew 3 screws from lower cover on steering column shaft
and remove the lower cover.
3. Unscrew 4 screws from clock spring and remove the clock
spring
Installation Notice
lDon’t try to repair and modify the clock spring.
lWhen aligning the neutral position, turn to clockwise until it
stops, and turn to counter clockwise until the marks are
aligned

SUPPLEMENTAL RESTRAINT SYSTEM(SRS) 8B-21
AIR BAG CONTROL UNIT(AC4)
Removal & Installation Procedure
AC4 is installed on the center portion of the front floor tunnel.
Built-in accelerometer sensor detects collision and determines
action or non-action and ignition time.
Notice
Do not disassemble the AC4 to repair. If defective, replace it.
AC4 should not be shocked or vibrated by dropping on the
ground or bumping.
Replace the AC4 with new after air bag inflation.
1. Disconnect the negative battery cable and wait for 30
seconds before starting service.
Notice
Though battery cable is disconnected, air bag control unit
will maintain backup power for 150ms and air bag can be
inflated, so wait for min.30 seconds.
2. Remove the console box and center fascia panel assembly.
3. Remove the heater control switch and audio assembly.
4. Remove the lower side panel of the driver’s portion and
glove box.
5. Remove the lower main panel.
6. Release the lock lever of the AC4 connector and disconnect
the connector.
7. Unscrew 3 nuts and remove the AC4.
Notice
For installation, horizontal position should be secured for
the better changes of collision pulse between the vehicle
body and air bag control unit.
8. Installation should follow the removal procedure in the
reverse order.
Inspection Procedure
1. Check AC4 case and welt bolts for crack or deformation.
2. Check connector, lock lever and terminal for deformation.
Notice
Replace the AC4 with new if dust, deformation or corrosion
found.

8B-22 SUPPLEMENTAL RESTRAINT SYSTEM(SRS)
GENERAL DESCRIPTION
AND SYSTEM OPERATION
INTRODUCTION
SRS (Supplemental Restraint System) air bag protects driver
and passenger by inflating air bag under collision and seat
belt pre - tensioner is a supplemental equipment for seat belt
reducing shocks from the collision by pulling passenger’s body
against seat back at the same time of air bag inflation.
Air bag unit has diagnosis functions and indicates system
malfunctions to the driver by turning on the air bag warning
lamp.
CAUTION
Perform the service procedures for the air bag system as
ordered, if not, the air bag can be operated suddenly and it
could result in damage of air bag or injury. Before service
(removal, installation, checking and replacement of parts),
observe the following instructions and service correctly.
1. To service, turn the ignition switch to ‘LOCK’ position and
disconnect the negative battery cable and continue the
procedures after approx. 30 seconds.
2. If the vehicle is damaged due to accident, remove the air
bag ECU first to get the accident records.
3. Never use the other vehicle’s air bag parts and replace
with genuine part, if required.
4. Do not disassemble or repair the air bag module, air bag
unit and wiring harness to reuse.
5. Replace the air bag unit or air bag module if dropped,
cracked or damaged.
