2018 Cascadia differential light coming on and off.

Do you have locking differentials?
Have you driven through some deep snow lately?
The last couple of trucks I’ve had, deep snow ripped out the lock position sensor wires on the axle.
I was just able to reattach, and hold the plug on with zip ties.

 

Hi were you able to find the solution ?
Please let me know if you were able to fix it, I am having a same problem and it’s very annoying and bad for ears at the same time.
Thanks in advance ! Below is my email

On another truck, the light was on dimly. I pulled the sensor connector and found water, it was causing a limited shorting of the pins.
Dried it all out, worked good after that.

 

My 2013 Star was doing this before we sold it. It was the plug in right on the diff. Was green from the salt inside.

 

Thanks for you response.
Where is the sensor connector I will check it out but this sound is really driving me crazy and I can’t take this no more.

 

You do not have a diff on your front wheels? Unless you have a powered front steer axle?

 

You can also just unplug it if it wont stop coming on and buzzing. Mine was driving me crazy. I found this thread and pulled over and checked the plug in. It was unlocked and halfway off so i plugged it back in and locked it. Its been fine every since.

 

Hi I have almost the same problem , have you found the solution?
