No Horn, and airbag light is on, but cruise control works

Hi,

I am wondering if it is the clock spring that has went on my 02 Tacoma?

 

It does. It’s likely something has gone wrong in the wiring. I’d be willing to bet your cruise control will stop working before long as well. Same thing happened to my ‘99.

 

the horn / airbag has been like this for years now. The cruise control is still kicking. So, you think it is the clock spring then?

Thanks

 

Try holding the horn button down while turning the wheel, if it honks intermittently while doing that then it's definitely the clockspring. If it doesn't I'd pull the codes from the Airbag Module and see what you have first.

 

In my experience I would think so, but Dm93 brings up a valid point of holding the horn down while turning or pull the code from the airbag before tearing everything apart.

 

I'm not 100% sure for the tacoma but when the clock spring on my 09 corolla went bad, I lost the cruse control function, horn, and the srs light turned on.

I would think cc is tied to the clock spring for the tacoma also unless you got an aftermarket cc setup.

 

I just replaced my clock spring. Cruise control worked, and airbag light wasn't on, but my horn didn't work. Clock spring replacement fixed the horn.

I was pretty sure it was the clock spring causing the issue because the horn would go off when I hit the panic button on my key fob, but not when pushing it on the steering wheel - at any angle or at full crank.

 

Weird stuff going on here for sure

 

The clock spring is basically a long ribbon cable with several wires wrapped in a spiral. Airbag usually uses 4 of those wires, horn uses 1, cruise control uses 2. Newer trucks with stereo controls, Bluetooth phone controls, adaptive cruise, lane departure warning, etc. use clock springs with more wires. The wires often don't all break at the same time.

On an '02 without the complications of CANbus, the clock spring is the most likely suspect.

How the heck did you drive for years without the horn? I use my horn at least twice an hour thanks to rush hour traffic
