Why is my traction control light on and why doesn't my cruise control or Eco work?

Asked by May 16, 2016 at 07:10 PM about the 2012 Ram 1500 Tradesman Crew Cab

Question type: Maintenance & Repair

I'm such a dummy. I have a 2012 Ram 1500 that needs inspection, but I have
a code light on and cannot clear the monitors without the code light going
back on again. What I can tell you is in my question:  Why is my traction
control light on and why doesn't my cruise control or Eco work? Is it a fuse?
Please help this idiot..Thanks much folks.

Scan it for codes it has a bad WSS (wheel speed sensor) control this sends a signal to the vehicles computer and NO CRUISE along with the Traction light ON is because a wheel is not sending its signal to the computer... ONCE again a decent scan tool will indicate which wheel sensor needs to be serviced / replaced

Take it to a local autoparts store and get the code read. This is usually a free service. Post the code(s) here on the forum and someone may be able to help you. Also if there is a chance that the truck is still covered by emissions or power train warranty, the dealership can fix it for you.

More than likely a wheel speed sensor once you figure out which one find a wiring diagram.

My 2008 did the same thing, I found a broken wire over the left rear axle. It was a available wire inside the lump or wire harness just above the axle on the left Side.once I fixed that all lights went put and my cruse worked like it should.
