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. Check the clock springs and 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. Service and Repair.

Pre-Removal Operation
- Set the steering wheel and the front wheels to the straight ahead position, and then remove the ignition key.

REMOVAL SERVICE POINTS



Step 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. Vehicle Damage Warnings.

INSTALLATION SERVICE POINTS
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. Service and Repair

2. Connect the battery (-) terminal.




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

CAUTION: Turn the ignition switch off before disconnecting or connecting the scan tool.

4. Turn the ignition key to the "ON" position.
5. Conduct diagnostic test using the scan tool to ensure entire SRS operates properly.




6. Turn the ignition key to the "LOCK" position. Disconnect the negative battery cable and tape the terminal to prevent accidental connection and airbags deployment.

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





Step 6 --- Clock Spring Installation
Align the mating marks of the clock spring. Turn the front wheels to the straight ahead position. Then install the clock spring to the column switch.

Mating Marks Alignment
Turn the clock spring clockwise fully. Then turn it back approx. 3 1/8 turns counterclockwise to align the mating marks.

CAUTION: Ensure that the clock spring's mating marks are properly aligned. If not, the steering wheel may not rotate completely during a turn, or the flat cable in the clock spring could be damaged. This would prevent normal SRS operation and possibly cause serious injury to the driver.




Post-installation Inspection
1. After installing the clock spring, the steering wheel, the column covers and the air bag module, check steering wheel for noise, binds or difficult operation.
2. Reconnect the negative battery terminal. Turn the ignition key to the "ON" position. Does the "SRS" warning light illuminate for about 7 seconds, turn OFF and then remain OFF? If yes, SRS system is functioning properly. If no, Testing and Inspection.

Clock Spring Check




1. Check connectors and protective tube for damage, and terminals for deformities.
2. Visually check the case and the gears for damage.







3. Check for continuity between the No. 1 connector of the clock spring and connectors No.3 and 4.




4. Align the paint mark of the SRS check harness connector No.4 with the notch in clock spring connector No.2 (arrow in the illustration) to connect the connectors Nos.2 and 4.
5. Check continuity between the terminals 22 and 23 of the SRS check harness connector No.5.
