Trouble codes U1110 U1120 U0416 P0309 - 2008 Jeep Compass

What engine? v 10?
what is the question, non was asked
did you look them up in the fsm yet> if not why not look first?
factory service manual,
or alldata.com
each has a meaning and more test to find true cause.
same answer all cars., look, read, read how it works , then do tests
to isolate and diagnose why its happening.

or get it serviced.?
learn to do it, or get someone who already knows how.
ill do the 1st one (not all , im to lazy today)

if you learn to use google , you will see others have this. why not look.
309 is misfire#9 ( a v10 engine)?

u1120 is data comms loss, you need service.

is the cars battery fully charged, to 12.6 volts rested
is car running right with full power, sad i have to ask this huh?
get it serviced, or read the FSM on all codes and see that you cant
proceed with out a scan tool, right>?
