immediately. It returns to ON automatically. When engine is on, do not turn the key to this position.
Notice:
(1) Do not pull the key out or turn it to LOCK before the car is fully stopped, or there will be dangers caused
by locking steering wheel or disabling some safety functions.
(2) It is prohibited to drive the car with engine turned off to ensure functioning of braking and steering booster.
(3) Do not let the key stay at ON for a long time when engine is off, or the battery fully discharged.
(4) Shift to neutral gear before ignition key is switched to START.
(5) Turn the steering wheel lightly after the car is fully stopped to make sure it is locked.
3.Unlock Steering Wheel

b. The connector for damage and distortion.Notice
If pitting, crack or distortion is found on an ECU, replace it with a new one.VII. Airbag assembly & clock spring1.Removal and Installation of driver airbag and clock spring
Operations prior to removal
(1)Take out the ignition key after the steering wheel and front
wheel are adjusted to straightforward direction.
(2)Remove negative (-) terminal cable from the battery.
Removal procedures of the driver airbag assembly:
(1) Unscrew the screws of the two sides, see fig.15-65SRS (Supplemental Restraint System)-SRS-General Information (2) Check after installation.
a. Turn the ignition switch ON.
b. The warning light goes on within 4s, and then goes out.
(3) If the light doesn't go out, check the trouble and eliminate it.
For other ECU inspections, see Troubleshooting.
fig.1
(2) Disconnect the connector of the wire harness.
(3) Remove the components of airbag assembly.
(4) Remove steering wheel.
Removal procedures of clock spring:
(1) Remove the driver airbag assembly (disconnect the connector).
(2) Remove steering wheel gently (see the precaution).
(3) Remove the steering column cover and disconnect the connector of wire harness in the lower end.
(4) Remove clock spring.
Installation procedures of the driver airbag assembly
(1) Pre-Check
1- Install steering wheel
2- Connect the wire harness
3- Install driver airbag assembly
4- Screw up the installation screws of the two sides
(2) Connection of the negative (-) terminal of the battery
(3) Check after installation.
Installation procedures of clock spring:
(1) Pre-Check
1- Connection and fixation of the clock spring and combination switch
2- the connector of wire harness in the lower end
3- the steering column cover
4-Thread the line at the upper end of the clock spring through hole on the body part of the steering wheel
5-Install the steering wheel
6-Connect wiring harness
7-Install the airbag assembly components
(2) Connect the negative (-) terminal cable of the battery
(3) Check after installation5-66Key points for installation
(1)Pre-Check
a. The new airbag or clock spring shall be checked before being installed.SRS (Supplemental Restraint System)-SRS-General InformationNotice
Use scanner to do adiagnossis of airbag circnit, not to break down.
Keep the removed driver airbag assembly upside down in a clean and dry place.Notice
Keep the removed clock sprint in a clean and dry place.fig.2Installation nutRemoval of steering wheel (see the figure 2)
(1) Remove the installation screws from the middle and remove
the steering wheel.(Disconnect the horn connector)
5-68Notice
The circuit resistance of the airbag assembly (squib) cannot be measured even with a designated tester.
Since there is current flowing in the squib, when a tester is involved in measuring the resistance, sometimes
the airbag is unexpectedly deployed in case of static electricity, leading to serious accident.
(2) Check the clock spring
Check the following items, and replace the clock spring if any badness is found.
a. Check the connector and protecting tube for damage and the terminal for distortion.
b. Check the case for damage.
c. Check and see if the joint terminal at the upper end of the clock spring are in conduction with that at the
lower end.
d. A thin probe shall be inserted from the back of the yellow connector of the clock spring.
e. With reference to the figure below, insert thin probes into the current tester to check the conduction of the
terminals.VIII. Key points for scrapping the airbag assembly The airbag shall be deployed according to the following procedures before scrapping the airbag assembly or
a vehicle installed with an airbag.
1. Scrapping of an airbag assembly prior to deploymentNotice
The airbag shall be deployed before being scrapped.
The airbag shall be deployed outside the vehicle before being changed.
The airbag shall be deployed in the vicinity of a smoke detector since smoke will appear when the airbag
is deployed.
When being deployed, the airbag will create much noise. People nearby shall wear noise muffler to close
their ears. Avoid do the job within the residential areas.
Deploy inside a vehicle
1) Park the vehicle in a flat area
2) Disconnect the positive (+) and negative (-) terminal cables from the battery and remove the battery from
the vehicle.SRS (Supplemental Restraint System)-
