Tow haul mode and reverse sensors/camera gone together?!

[integrityinc]

So, I just pulled into Rapid City, SD tonight. Drove over 550 km today, uphill the majority of the way, with a head wind,in +39 Deg C weather, pulling my 37' Jayco Recon ToyHauler ( approx 14 or 15k lbs ). What a long day!!! My truck performed flawlessly.... Almost...
When I got to town, there was 1 long fairly steep hill that I had to climb from a dead stop at a red light. No big deal.
Climbed it, then noticed my tow haul light had switched off...never happened before, now it won't come back on!! Also, my reverse sensors suddenly stopped working along with the rear view camera!!!

I have 1700 km to home from here, is this an easy fix or am I the next guy in line at the dealership? I really don't want to go w/out tow haul for that long!! It makes the hills so much easier when you can hold your rpm where you want it!

Any help is appreciated!!
Thanks guys!

If you open the fuze panel on the passenger side of the truck under the glove box and look at fuze 34 it will most likely be blown. You can open the owners Manuel of the truck and about half way through there is a chart that number the fuzes and tell what they do. I had the same issue with mine. Except mine was tow haul traction controll and 4wheel drive instead of tow haul sensors and cameras. Check that fuze it could be an easy fix where you just replace the 10a fus that controlls these items but it could be an issue with your wiring harness under te steering wheel. These harness get chaffed and can short circuit wires leading to fuze failor

#34 was the magic number! Thanks a bunch!!

And before I even changed it the camera came back on... Right after my daughter played a DVD on the nav system. Weird.

Thanks again!

No problem buddy glad I could help

So it popped again ... Where is that wiring harness that could be shorting? Can you point me in the right direction?

You have to take off the steering column. And it is on the bottom side I believe
