I have a Dodge Ram Hemi 2013 that several u codes came up on. How do i find out what they mean without going to a dealer.

Asked by Aug 08, 2016 at 07:56 PM about the Dodge Ram 1500

Question type: Maintenance & Repair

Got in my truck this morning and it wouldn't start.  My son came down and reset the key fob.  Brought his diagnostic computer and checked it out.  I had six codes come up.  The dodge dealership here wants to charge $160.00 just for the dia/test. Can anyone tell me what these codes are: U110C , U1110, U1120, U1403, U110E, AND U0140.

The "U" codes are set by other modules that sit and communicate with the PCM on the same CAN- BUS. They're mostly for body related functions ... U1120 means the PCM doesn't receive a vehicle speed signal from the Anti-lock brake Module over the CAN C bus. This can be caused by the ABS module, PCM or something wrong with the can bus.

Thanks
