U1110-LOST VEHICLE SPEED MESSAGE
When Monitored: With the ignition on, battery voltage between 9 and 16 volts, and engine run time greater than 3 seconds.
Set Condition: The PCM either doesn't receive a bus message or receives an implausible bus message from the Anti-Lock Brake Module.
Possible Causes
CAN C BUS OPEN OR SHORTED CONDITION
NO POWER TO ANTI-LOCK BRAKE MODULE — MODULE UNPLUGGED OR OPEN FUSE
POWERTRAIN CONTROL MODULE (PCM)

Shifting problems
Can someone explain what a Can c bus is or where to find it. My dodge doesn't shift to 3 and higher. Changed the abs sensor speedsensors in and out, checked all fuses and changed transmission fluid and filter. Code says u1110
thanks in advance

can bus is just the communications protocol the various electronics use to talk to each other. u1110 is telling you the PCM is not getting a speed reading from the anti-lock brake module. Does your speedometer work?

Shifting problems
First it didn't.. but after checking the fuses, I found one missing, one with the much amp and one who was broken.
speedometer and odometer are working just fine now.
I changed the abs sensor and both speedosensors on the gearbox at driversside. It has a new filter and enough (and not to much) transmission fluid.
I got it from an online auction and had it shipped to Bonaire where I live. First and last time I'll ever do that again. Had shifting problems from the first moment. Got a new transmission and changed it, still dose problems. Maybe a defect in the pcm??

Need to be able to hook a scanner to it, and see what the PCM thinks is going on. If it isn't getting good data for speed from all and sundry sensors, it is gonna be confused as to how to run the trans, etc.
