My wife was driving home today and the CEL came on. I ran the code and it came up with the following.. P1607 Serial Communication Problem With Device 7. I have no clue what that is. Any body have any ideas so I can go to the dealer and have a heads up?? The car is a 2006 Chrysler Sebring with 2.7 V6. It has 38,000 miles on it. Glad I have the 100,000 mile extended warranty.

Thanks in advance guys!

you have internal pcm failure.easy fix......you need new pcm which should be covered.has something to do with shutdown timer rationality...moe

 

My town and country just showed that code is the only solution reflashing? Any idea how much does it cost in phoenix az? I dont really get to understand the code can somebody explain it a bit better? Alternate solutions thanks

 

WHAT YEAR is your T&C, and how old is the battery and when were the cable connections last cleaned?

 

its a 2008 i check with the scanner it says battery has 12.1 bolts with car of terminals are clean dont know how old is the battery i just bought the car a week ago . Altought when car is running it usually puts out 13.3 bolts sometimes 13.8 but thats at its best idk if thats normal my infinity 2000 its usually at 14.1 bolts . Thanks in advance

 

With the strong computer demands on the battery(even when not in use) A weak or dying battery can give this code and other odd happenings. I suggest you get a battery load test done at say an Autozone or such auto parts store(they will do it for FREE). You may have a weak battery cell or a dying one, not knowing how old the battery is. At best 4 years is about the expected lifespan of a vehicles battery anymore.

 

Thanks ill check today and post results so far its apretty suv and comfortabke just little details

 

So after testing the battery and its was good. I reset the code in january now just today the code came back it seems ill have to stop at the dealer sometime to get the computer reflashed also i notice a shaking in the engine barely noticeable but you can feel it in park and drive with car in no motion its like it jumps at times i got no code but the one with the timer. and just put spark plugs and wires as well as all the motor mounts it might also be the computer may be but the sake its being there since i got the car around end of november it was worse but after motor mounts and tune up it diminished a lot. Anybody knows how to check the coil pack thats the one thing i never changed but it doesnt misfire at all in drive and pulls strong thanks

 

if you have not repair the problem related DTCs,even you clear the trouble,it will come back again.
