Dash turns off while driving. Then def needs service turns on

[scubaseth]

My Dash turned off then back on but my engine stayed on. Then def needs service turns on. My parking sensors also keep over sensing and go off.

I see alot of problems with dash lights staying on. But nothing about them turning off while driving and then back on.

sounds like a problem with a wiring harness. Especially check the ones going to the BCM which is about behind the brake pedal and there's a large one inside the frame rails on the driver's side around the front of the transmission

Thanks! I will look if the dealer can't find the problem. 4 days and nothing.

Funky things happen if your battery is starting to die.

I wouldn't think that would be such a problem while the truck is started.

They said they found 2 bad wires on a wiring harness. They couldn't find why the dash went off. Could of been related to the def wires being bad.

Along with 2 bad rear parking sensors.

Update. Dash shut off again. They said after 2 weeks that it was my battery terminals. Hmm not a great feeling of it really being fixed.
