Clockspring Assembly / Spiral Cable: Service and Repair
CAUTION:1. Never attempt to disassemble or repair the air bag module or clock spring. If faulty, replace it.
2. Do not drop the air bag module or clock spring or allow contact with water, grease or oil. Replace it if a dent, crack, deformation or rust are detected.
3. The air bag modules should be stored on a flat surface and placed so that the pad surface is facing upward. Do not place anything on top of the air bag modules.
4. Do not expose the air bag to temperatures over 93° C (200° F).
5. After deployment of an air bag, replace the air bag modules. Check the clock spring. If faulty, replace it with a new part.
6. Wear gloves and safety glasses when handling an air bag that has deployed.
7. An undeployed air bag module should only be disposed of in accordance with the procedures specified under "Undeployed Air Bag Module Disposal".
Pre-removal Operation
After setting the steering wheel and the front wheels to the straight ahead position, remove the ignition key.
REMOVAL SERVICE POINTS
NEGATIVE (-) BATTERY CABLE DISCONNECTION
Disconnect the negative battery cable from the battery and tape the terminal.
CAUTION: Wait at least 60 seconds after disconnecting the battery cable before doing any further work.
AIR BAG MODULE REMOVAL (DRIVER'S SIDE)

>B< CLOCK SPRING INSTALLATION
The content of this article reflects the changes identified in TSB-08-52B-001
A modified clock spring has been adopted for Service Parts on affected vehicles as of September 2007. New and old style parts are interchangeable. This TSB advises the procedures for alignment of the neutral point of the new clock spring when a part is replaced.
Parts Identification
Replacement Clockspring Alignment As Per Manual Update TSB-08-52B-001:
Mating Mark Alignment
Replacement Clockspring Alignment As Per Manual Update TSB-08-52B-001 (Part 2):
1. Turn the clockspring clockwise fully.
2. Turn the clockspring anti-clockwise (counter-clockwise) approx. 3/4 turns to align the mating marks.
3. Check that the white or yellow roller can be seen from the window for checking the neutral point when the mating marks are aligned.
NOTE: If the white or yellow roller cannot be seen or black roller can be seen, the neutral point is not aligned correctly.
4. Install the clockspring to the column switch.
CAUTION: If the clock spring's mating marks are not properly aligned, the steering wheel may not rotate completely during a turn, or the flat cable within the clock spring may be severed, obstructing normal operation of the SRS and possibly leading to serious injury to the vehicle's driver.
>C< STEERING WHEEL INSTALLATION
1. Before installing the steering wheel, be sure to first turn the vehicle's front wheels to the straight-ahead position and align the mating marks of the clock spring.
CAUTION: Be sure when installing the steering wheel, that the harness of the clock spring does not become caught or tangled.
2. After securing the steering wheel, turn the steering wheel all the way in both directions to confirm that steering wheel rotation is normal.
>D< POST-INSTALLATION INSPECTION
1. Turn the ignition key to the "ON" position.
2. Does the "SRS" warning light illuminate for about 7 seconds, and then remain off for at least 5 seconds after turning off?
3. If yes, SRS system is functioning properly. If no, consult Diagnostic Troubleshooting Flow.
