Clockspring Assembly / Spiral Cable: Testing and Inspection

CAUTION:
1. Never attempt to disassemble or repair the air bag modules or clock spring. If faulty, replace it.
2. Do not drop the air bag modules or clock spring or allow contact with water, grease or oil. Replace it if a dent, crack, deformation or rust is 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 it.
4. Do not expose the air bag modules to temperatures over 93° C (200° F)
5. After deployment of an air bag, replace the air bag modules. Inspect the clock spring, and replace it with a new part if it is faulty.
6. Wear gloves and safety glasses when handling air bags that have already deployed.
7. An undeployed air bag module should only be disposed of in accordance with the procedures.




If even one abnormality is discovered with the inspection in steps 1 to 4, replace the clock spring with a new one.

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




3. 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.
4. Measure between the terminals 22 and 23 of the SRS check harness connector No.5 to confirm that the resistance value is at the standard value.

Standard value: less than 0.4 ohms.
