i have a 05 pacifica. the other day the insturment cluster went dark during start up. i shut the car off and restarted it, still dark. i called the dealer they told me to pull the iod fuse to reset it. this worked. i pulled the codes with a reader and got u110c and u0140. the dealer told me it was just a fluke and not to worry unless it happenes while driveing. i took the car to a napa repair center for some other intermiten problems. i questioned them about these codes and they said it was a sign of the bcm going bad. but it has only done it once. so do i need to replace the bcm? and does it need to be programmed by the dealer? the factory service manule does not state that it is required, only to turn the igition on for 15 sec so the new module will learn the vin.
thanks for the help.

 

Both Fobs stopped working all of a sudden. disconnected battery, nothing. removed IOD fuse, nothing. did "ON, ACC, ON, ACC, ON" to check for BCM code, no code but fixed problem? Why?

 

the key on key off is for PCM not bcm codes.
