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.

260(4) Check the installation status of the airbag assembly.
4. Driver airbag assembly (see the figure below)
5. Clock spring (see the figure on the right)
(1) Check the union joint and protecting tube for damage and the
terminal for distortion.
(2) Check the case for distortion.
6. Steering wheel, steering column and steering lower shaft component.
(1) Check the installation status of driver airbag assembly.
(2) Check the steering wheel for any abnormal noise and see if the
clearance is normal.
7. Check the wire harness joint (instrument panel wire harness).
8. Check and see if the wire harness is securely installed, if the joint is damaged and if the terminal is
distorted.NOTICE
1. Work must be started 60s after the negative (-) terminal cable is disconnected from battery. The
disconnected negative (-) terminal cable shall be protected with insulating tape for insulation.
2. Airbag assembly and clock spring shall not be removed or repaired. They shall be replaced if there is
any trouble.
3. Pay enough attention to airbag assembly and clock spring when using, avoiding dropping them onto the
ground or into water or oil. In addition, if there is any pitting, crack or distortion on them, replace with
new ones.
4. When an airbag is deployed, the deployed surface should face up. It should be kept on a flat surface
without any other items on it.
5. Don’t keep an airbag in a place where the temperature is higher than 93°C.
6. When an airbag is deployed, it shall be replaced with a new one; simultaneously, check the clock spring,
and replace it with a new one if found abnormal.
7. When deal with the deployed airbag, gloves and protective glasses are to be used.
8. When scrapping the undeployed airbag, it shall be discarded after being deployed.GeneratorBracketDriver Side Clock SpringTo HornTo Driver Module

a new one.
4. Every time an airbag is deployed, the ECU shall be replaced with a new one.
5. When disassembling or maintaining the parts around ECU, attention must be given to avoid contacting
the ECU.NOTICE
If the ECU cannot be installed correctly, the airbag will not act normally.

2635. Check:
1 ECU case for pitting, crack and distortion.
2 The joint for damage and distortion.
For other ECU checkings, see Troubleshooting.II. AIRBAG ASSEMBLY & CLOCK SPRING1. 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.
2. Removal procedures of the driver airbag assembly:
(1) Unscrew the screws of the two sides.
(2) Disconnect the connector of the wire harness.
(3) Remove the components of airbag assembly.
(4) Remove steering wheel.
3. Removal procedures of clock spring:
(1) Remove the driver airbag assembly (disconnect the connector).
(2) Remove steering wheel gently (see the precautions).
(3) Open the upper closure of the combination switch, locate and
disconnect the connector of wire harness in the lower end.
(4) Remove clock spring from the steering wheel.
4. Installation procedures of the driver airbag assembly
(1) Pre-Check
ySteering wheel
yConnect the wire harness
yDriver airbag assembly
(2) Screw up the installation screws of the two sides.
(3) Connection of the negative (-) terminal of the battery
(4) Check after installation.NOTICE
If pitting, crack or distortion is found on an ECU, replace it with a new one.NOTICE
Put the removed driver airbag
assembly upside down in a clean
and dry place for care.NOTICE
Put the removed clock spring in
a clean and dry place for care.

2645. Installation procedures of clock spring:
(1) Pre-Check
yThread the line at the upper end of the clock spring through hole on the body part of the steering
wheel
yConnection and fixation of the clock spring and steering wheel
(2) Install the upper hood of the combination switch
(3) Install the steering wheel
(4) Install the airbag assembly components
(5) Connect the negative (-) terminal cable of the battery
(6) Check after installation
6. Removal of steering wheel (see the figure below)
(1) Remove the installation screws from the middle and remove the steering wheel.(Disconnect the horn
connector)
NOTICE:
Due to the tight engagement of the spline and the steering column, it is hard to separate the steering wheel
from the column. Don't try to remove the steering wheel by force (otherwise the clock spring under the
steering wheel will be damaged). The correct way is to turn the nut on the steering column shaft end for
several pitchs and then lift the steering wheel upward.Use Allen
Key Socket

265III. KEY POINTS FOR INSTALLATION1. Pre-Check
(1) The new airbag or clock spring shall be checked before being installed.
(2) Connect negative (-) terminal cable of the battery.
(3) Connect Hi-DS T to the diagnostic interface (16 connector).
(4) Turn the ignition switch ON.
(5) Read the diagnostic circuit and see if the other locations than the troubled area of the airbag are normal.
(6) Turn the ignition switch ON.
(7) Remove the negative (-) terminal cable from the battery, and protect it with insulating tape for insulation.
2. Installation of clock spring: align the clock spring and install it to the
steering wheel.
yCenter alignment of the clock spring
Screw up the clock spring clockwise to the end, rotate it counterclock-
wise by 2.5 turns, and align it with the mark (see the figure below).
3. Install the components of the steering wheel and airbag assembly
(1) When the center of the clock spring is aligned, install the components of the steering wheel and airbag
assembly.
(2) After being installed, rotate the left and right sides of the steering wheel to position, and make sure there
is no abnormality.NOTICEIn case of scrapping an airbag, it shall be noted that the airbag shall be deployed according to the specifiedprocedures before being scrapped.
When connecting or disconnecting the Hi-DS T, turn the ignition switch OFF first.NOTICE:
Work must be started 60s after the negative (-) terminal cable is disconnected from battery.NOTICE:
If the center of the clock spring cannot be aligned, the steering wheel
will not turn midway, or cause bad performance to the clock spring
circuit, consequently hamper the normal action of the airbag.NOTICEWhen installing the components of the steering wheel and airbag assembly, attention should be given toprotect the wire harness of the clock spring from seizure.
