I have check engine light on. I went to advance auto parts, they told me about this code U1110. What does that mean for my vehicle?

Trying to see why my car is acting crazy.
First the check engine light then ABS light came on then and then slippery one and break light when brake was not on, then they all went off except the check engine and break light.
Sometimes my car key will not work to unlock the car or push start and if I put the key in the ignition it will not crank also. But, the lights come on as usual and the car says push brake to start but does not do anything.

Do any of these problems occur once the engine is running? If not, the first thing I would look at is the battery. Every circuit and system now has a computer involved with it, and they are very intolerant of low or unstable voltage. Measure the battery's voltage with the engine off, then again with it running. Use a digital voltmeter so you can read to the tenth of a volt accurately. Let me know what you find.

U1110-Lost vehicle speed message.

When monitored: With the ignition on, battery voltage between nine and sixteen volts, and engine run time greater than three seconds.
Set condition: The PCM either does not 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)
