Hi all. I had a check engine light come on. The stealer can't get my truck in for three weeks (welcome to Hawaii). I checked the sticky up top and got the diagnostic codes from my 06 Mega Cab Hemi. I got some codes that aren't listed as well as one that was. The one that was listed is P0571. The others that aren't are:

U110C
U0141
U1411
U110E
U1113

Does anyone know what these mean? Thanks!

 

P0571 - Brake Switch 1 Performance

U110C - Lost Fuel Level Message
U0141 - Lost Communication with FCM
U1411 - Implausible Fuel Volume Signal Received
U110E - Lost Ambient Temp Message
U1113 - Lost A/C Pressure Message

 

P0571 is a brake switch No. 1 Performance fault. Those other codes, I don't have a clue, you need P codes.

 

So what would cause the check engine light? Why all the codes all the sudden? This truck has 6000 miles on it. I never had this issue with my 04 Hemi...

 

Sometimes you can get crazy codes from the battery being weak. Also if the IOD fuse under the hood is not pushed in good crazy codes could appear. I would check the state of the battery. They can go bad after sitting on the lot until they are sold.

 

Thanks! I will take a look.

 

by the way P codes are for powertrain issues. U codes are body modles such as CCN, ORC, HSM, so on and so forth.

 

yeah i got a whole database of these codes from work...every code (P, U, & C) all up through 2009 1/2 lol

 

without any offense intended to kenihemi I was just tring to clarify what the prefix on a SAE code means
