Volvo Clock Spring

30889364 .

Up for sale is a good functional Volvo S40 classic steering shaft clock spring assembly. This is the unit that "connects" the air-bag & horns to their associated control devices. It does this through a spool of wire on a laminate film. This unit will turn about 4 turns to the right and 4 turns to the left. You can feel when it stops and see it through the clear housing, however If overextended, or if the steering wheel is removed from the car improperly (which is easy to do by accident) it will break immediately.

This unit must be installed correctly or it will break. Sometimes they simply loose continuity from old age, and you will get a continuous SRS light. If you are getting SRS lights, this is very often the cause of the problems. I have tested this unit for continuity with an ohm meter and it works properly through it's travel range. It will come to you as so. I will however not warranty this in any way because of the fragility of this unit, and the potential for destroying it if improperly installed. Therefore, this unit is sold "As-Is" Feel free to check it with your ohm meter when you receive it, it IS functioning perfectly.

Also !!please note!! Once the Air-Bag ECU has detected a clock spring fault, it will always illuminate the SRS light, even once the fault has been repaired, and even after disconnecting the battery overnight. You need to have the system fault cleared at a dealer or independent volvo shop with their specialty scan tool. This should only take about 2-5 minutes, but it IS the only way to clear an SRS fault once the light has been triggered on old style volvos! My volvo technician would usually do this for me at the price of a case of beer.
