Airbag Clock-spring:

The clock spring is simply a coil that retracts and expands inside its housing as the steering wheel turns. Its function is to maintain electrical continuity for all the components on the drivers airbag. The components include the airbag, horn, and any vehicle controls such as radio, cruise, heat and even telephone on some vehicles.


The clock spring only needs to be replaced when the connectors that attach to the drivers airbag is melted and fused directly to the cylinder. During a deployment the gas conversion creates a heat exchange inside the cylinder and that causes some connectors to melt.

 

Thank you,
I had no idea that is what it was called, I had visions it had something to do with a wind up clock of some kind..

In other areas of similar electrical/mechanicals I'm used to..we would call that a rotary joint or a slip ring..

Thanks again

 

I thought the same and in my mind it's still a slip ring! Old habits die hard!

 

Just another comment. You are correct. This took the place of the old slip ring and other spring loaded connections under the steering wheel. The old cars only had the horn and turn signal so less complication.

The clock spring wires wind and unwind as you turn the wheel. So you have a wired connection 100% of the time and it's much more reliable than the old slip ring setup. Clock-springs are a wear item because of the constant turning of the steering wheel and around 100K+ miles it's not uncommon for them to start to fail. They can be taken apart and cleaned and lubed but it does not seem to be a lasting repair.

Most of them are in the $100-$200 range so not too expensive.

Watch for other steering wheel controls to start acting up as was posted above.

But getting to it is fairly labor intensive as its buried in the steering column.

 

I find they only take minutes to swap?

Since everything is modular remove the airbag then the steering wheel and then the clock-spring cartridge is right there. Unplug the old one and plug in the new one.

But I have not changed one on a Jaguar so maybe more complication?

Not if the dealer does it...LOL

 

Update: Jaguar USA took care everything even the blind spot monitors. both sides went out. They cost $680.00 USD apiece just for the monitors I needed two plus labor. Once again thanks for your help with the suggestion to contact Jaguar USA.

 

Thank goodness we don't (heaven forbid) drive Honda's. The boy racers will be fewer if they don't fix this soon:

Interesting I wonder if this has anything to do with why my passenger side airbag light keeps going on and off randomly when I have a passenger.. Being the 3rd owner of this vehicle is there anything I need to do to make sure i get the mail for this recall or is for sure gonna come ?

 

Contact Jaguar USA and ask them to update the records for your VIN. I think they require a copy of the sales order with your address.

 

i just tried my vin and it told me LAND ROVER does not recognize my vin

 

I would think it has more to do with the pressure sensor in the seat than the actual airbag. The other possibility is the sensors control unit needs replacement or remapping.

 

I thought 2012 and up were exempt, but just got a Carfax notice for a passenger side recall:

Anyone know about this? Tried checking my VIN at safercar.gov and airbagrecall.com (official Takata recall site), but nothing shows up.

EDIT: NM, looks like it's legit. I guess they got more findings and the announcement was just made recently:

so how far up the year models does this go? Where does it end !!!

 

It looks like just 2012, for now at least...

 

I have been following this from last year. And every time that I go back and run my VIN, it says that there is no remedy yet. My problem is that I am in Guam and there is no Jag dealer here. But there is a Land Rover dealer. So they might have to do the recall repairs.

 

I was wondering if there is any traction yet, I too checked the vin for my 2010 supercharged and it just says "no remedy yet"

 

My Xtype (RIP...my first) started doing this towards the end of its time on earth. There are three sensors on the seat, the one that is on the bottom of the seat cushion is the one that needs replacing.
