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 module to temperature over 93°C (200°F).
5. After deployment of an air bag, replace the air bag modules and check the clock springs. Replace them with new ones if any problem is found.
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.

Pre-Removal Operation
- After setting the steering wheel and the front wheels to the straightahead position, remove the ignition key.

CLOCK SPRING

Removal

1. 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.

2. Air Bag Module Removal (Driver's Side)
1. Remove the air bag module mounting nut using a socket wrench from the back side.
2. When disconnecting the connector of the clock spring from the air bag module, press the air bag's lock toward the outer side to spread it open. Use a screwdriver to pry gently as shown in the figure at the left, to remove the connector.

CAUTION:
1. When disconnection the air bag module-clock spring connector, take care not to apply excessive force to it.
2. The removed air bag module should be stored in a clean, dry place with the pad cover face up.

3. Steering Wheel Removal

CAUTION: Do not hammer on the steering wheel. Doing so may damage the collapsible column mechanism.

4. Remove column cover lower
5. Remove clock spring and body wiring harness connection
6. Remove clock spring

Pre-Installation Inspection
1. When installing the new air bag module and clock spring, refer to "INSPECTION"

CAUTION: Dispose of an air bag module only according to the specified procedure.

2. Connect the battery (-) terminal.

3. Connect the scan tool to the data link connector then check diagnostic trouble codes.

CAUTION: Make certain that the ignition switch is OFF when the scan tool is connected or disconnected.

4. Turn the ignition key to the "ON" position.
5. Conduct diagnostic test mode using the scan tool to ensure entire SRS operates properly, except open circuit of air bag module (diagnostic trouble code No.22, 25).

6. Turn the ignition key to the "LOCK" position, disconnect the negative battery cable and tape the terminal.

CAUTION: Wait at least 60 seconds after disconnecting the battery cable before doing any further work.

Installation
To install reverse the removal steps and note the following.

Air Bag Module Installation:

2. Air Bag Module Installation (Driver's Side)
Install the air bag module, taking care that the wiring is not pinched.

3. Steering Wheel Installation
1. Before installing the steering wheel, turn the vehicle's front wheels to the straight-ahead position and align the mating marks of the clock spring.

CAUTION: 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.

6. 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 mark is 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.

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, refer to Air Bags (Supplemental Restraint Systems)/Testing and Inspection/Procedures.
