Re: u1041
Code U1041 means that the other computers have lost communications with the EBCM. Usually it's a loss of power, ground or a bad module. There is a Service Bulletin pertaining to this concern:
PI00714A Follow the service manual diagnostic procedures and specifically check G110 at the radiator core support berfore replacing the EBCM. This ground is located on the driver side under the head lamp connections. This is the radiator support. I have also found that the radiator support itself has had high resistance to the battery ground.
