It has happened 4 times, I hit a decent bump while driving down any road and my ABS and BRAKE lights come on and my Speedometer cuts out and stays at 0. When I turn the truck off, the lights go away and the speedo works, but the check engine light comes on until I hit the next bump...

the DTCs are:
U1412
U1417
U1418
P0501
C103D

They all say that they have something to do with Implausible Wheel Distance or Speed Sensor Performance Erratic.

Any ideas as to what may be causing this and/or how to fix it?
Thanks in advance guys.

Did you ever resolve the source of your x-mas tree problem ? I got the exact same situation at hand, and was hoping for a couple of helpful pointers.
RAM 1500 4.7L V8 Gasoline 2006 on my side.

U1417

Hits a bump, speedometer goes out, engine, brake & abs turn on, lots of beeping, and sometimes it just acts the reverse, bumping it fixes it while riding it just keeps beeping on&off.
I was suspecting bad or loose connectors, or a broken PCM (melted chip connectors or something) but I'm surprised I can read the codes in the first place.

 

If a bump brings it on, that's a bad connection somewhere. Might be as simple as a bad ground. See which connector those systems popping codes have in common.

 

According to my diagram reading, all these wires lead to the Controller Antilock Brake ?

 

Reseat the connectors on it a couple times, see if anything changes.

According to theory, if you correct the problem, the PCM should figger it out fairly quickly, and turn off the assorted lites.
