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.
2664. Check after installation
(1) Slightly rotate the steering wheel left and right, make sure that there is no abnormality or noise. (Driver
airbag module, clock spring)
(2) Turn the ignition switch ON.
(3) The warning light goes on within 6s, and then goes out.
(4) The trouble shall be eliminated if the warning light remains on when the ignition switch is turned on or
after it goes out after 6s.IV. CHECKING1. Driver airbag assembly checking
Check the following items and replace the related components of the airbag assembly if any badness is
found. The old components shall be deployed before scrapping.
(1) Check the hood for pitting, crack, distortion, etc.
(2) Check the joint of the wire harness for damage and the terminal for distortion.
(3) Check the case of the gas generator for pitting, crack and distortion.
(4) Check the installation status of the airbag assembly.
2. Check the clock spring
Check the following items, and replace the clock spring if any badness is found.
(1) Check the joint and protecting tube for damage and the terminal for distortion.
(2) Check the case for damage.
(3) Check and see if the joint terminal at the upper end of the clock spring are in conduction with that at the
lower end.
(4) A thin probe shall be inserted from the back of the yellow connector of the clock spring.NOTICE
If there is pitting, crack or distortion, replace the airbag assembly with new one. The old components of the
airbag shall be deployed before scrapping.
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, sometimesthe airbag is unexpectedly deployed in case of static electricity, leading to serious accident.
