What does trouble code p127e mean in a jeep compass

No because if the phone connection works, it means the radio amplifier works. You either have a radio stage issue or an aerial issue. In fact it appears to be a well known issue!

p1622 is a manufactures test code cylinder select if the check engine warning is not on dont worry about it

no actual question asked, why?
what country????
what engine" is it gas or diesel or flex fuel what?
what fuel is it burning now.
p2 means factory code. (means unique to your driveline, only)
now i get to guess which engine.
here is my wild and useless guess based on NO ENGINE
http://www.engine-codes.com/p2017_jeep.html

which engine, gas or diesel and size?
P codes are power train, so... we need what engine,
USA list

• 2.0 L World I4 (gasoline)
• 2.0 L VW I4 (turbo diesel)
• 2.2 L OM651 I4 (turbo diesel)
• 2.4 L World I4 (gasoline)

we can't ever guess engines.....
P1616 (not b)?
the other shoe drops. ?
car runs?
good.?
headlights work full bright?
scan it yet, that means using any full scan tool.
id bet there are more DTC, not seeing them all or reporting all
makes help impossible.

you need a scan tool pull code and then you can clear trouble codes. if cause of code not fixed check engine light will come back on.

Sounds like it is misfiring. Go to Autozone (or similar) and they will connect a scaner to your car's computer to read the DTCs (Diagnotic Trouble Codes) and print them out for you to know exactly what is going on. It is a free service.

Code P127E, fuel pump control circuit 2 open, this means that your vehicle computer is sending the ground signal to the fuel pump relay or whatever is suposed to suply energy to the fuel pump, when this hapens and you do get energyse the fuel pump, the compueter gets a feedback that the pump is getting juice, what hapens here particularly is that the relay or what ever closes or trips the circuit like a switch, the contact is not phisically completed therfore no juice to the pump.
