Okay, I just received the bluetooth ODB II reader and tried it out. It works! This is the one I have:
I installed the "ODB Auto Doctor" Windows phone app and it was successful in interfacing with the ODB II reader. It showed two error codes, U110C and U11DD. I haven't been able to find out a lot about these yet, so if you anyone knows of any good reference sites for error codes, please let me know.
I upgraded "ODB Auto Doctor" to the Pro version and was successfully able to clear the two error codes. I also was able to see other engine status in real time.
For U110C I did find this on a dodge forum:
U110C-NO FUEL LEVEL BUS MESSAGE
When Monitored: Ignition on.
Set Condition: No fuel level BUS messages received by the PCM for 20 seconds.
COMMUNICATE WITH CLUSTER
