It is the law that proprietary information on engine management systems and monitors is the right of the manufacturer exclusively for three years after manufacture. Tool companies took the manufacturers to court years ago to get them to release this info but lost. It has to do with having the vehicles fixed at the dealer while they are under warranty to provide the dealer with some profit from factory warranty support and to be able to monitor the fault data on new vehicles when they show up. Your vehicle should still be covered by the warranty. Try it.
Or ask your tech to go into the engine management using generic OBDII this might give him some non manufacturer info and codes related to monitors. OTC is one of the best scanners for this but I can't garuantee it will work on the Compass.

SOURCE: I have a 2007 jeep
"U-codes" (codes beginning with a "U" prefix) are communications faults. Your vehicle is equipped with several computer modules which are all networked to gether on what is called the "Control Area Network" or "CAN". When one of the modules failes to communicate or if there is invalid data being transmitted by one of the modules, a U-code is stored in continuous memory in one or more of the other modules.
In your case, U1403 pertains to invalid or implausible data being recieved from the fuel level sensor by the Powertrain Control Module. Please note that this is NOT a fuel level sensor failure code and does NOT indicate faulty fuel level sensor circuits.
Theory of Operation
The TIPM receives a fuel level signal over CAN B from the Cluster. The TIPM transmits the fuel level message to the PCM over the CAN C bus.
The possible causes of this code are:
> Open or shorted CAN B circuit
> Instrument Cluster (CCN)
> Totally Integrated Power Module (TIPM)
> Powertrain Control Module (PCM)
To properly diagnose tis code, you must use a scan tool to access and verify data on all available modules. You must also determine if this is an active fault or an intermittent fault.
I don't see a fuel level signal problem at the PCM causing your engine to stall. However, the fuel level signal may be getting lost or "scrambled" due to a lack of communications between modules or a malfunctioning module. This could cause all sorts of problems (including stalling).
I would also like to add that my personal experience with this type of problem (communications faults) has taught me that the FIRST thing that should be done is a THOROUGH check of the BATTERY and CHARGING SYSTEM before attempting any communications diagnostics. If your battery is more than 4 years old, it is VERY LIKELY be the ROOT CAUSE of the problem. Computers tend to do all kinds of wierd things when they are not being fed properly.

Testimonial: "Thank you . We now have a place to start."
P000A is either wiring fault, a fault with the ECU/PCM or a mechanical fault the camshaft.
P000B is slow response from the cam sensor. It can be cause from dirty oil or the wrong type of oil.
In both cases, if your sure the oil is correct then there is an issue with the cam sensor or cam sensor solenoid.
I hope this helps; remember to rating this and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment.
Have a nice day and thanks for using FixYa.
