Truck Went Crazy

[Olson3422]

So Friday night went back the truck into the garage and a couple of chimes went off look down and abs on.

Ok, I will look into it when I get back from my fishing trip.

Go to leave in the morning start the truck pull it out of the garage and a list of crap goes off.

Abs, engine light, service electronic brakes, service electronic throttle, air ride suspension, and no light but no 4wd on the speedo.

Looked up codes and intermittent abs reading and vehicle speed sensor.

I replaced the sensors on the transmission still no fix.

Hooked up the scan tool and all-wheel speed sensor are reading but the vehicle speed is 317.62.

Any ideas out there?

See attached information from Mopar Tech Authority. Are you able to scan the ABS module? If no ABS “C” codes present then I would check the rear wheel speed sensors or tone wheel for damage.

No "c" codes but with the snap on scanner it shows all 4 wheels are showing speeds but the vehicle speed shows 317.62 rather I am driving or parked.

I'd guess that they are all stem from a CAN BUS issue, module or ECM.

Is the truck stock or modified?
