Obd code U1041
Codes U1XXX (where XXX stands for several possible numerical digits, 001 - 254) are communications fault codes. The first part (U1) tells you that there is a communication problem with one of your many onboard control modules. The second part (XXX) or in your case, (041) tells you which module is not communicating. It can vary from year to year, model to model. so without knowing the year and model of the vehicle we are talking about, I cannot tell you which one.
In any case, there is a module that is not communicating with the other modules that are sharing information through the Class 2 serial data circuit. One module uses U-codes to tell on the other modules. For instance, If you got the U1041 code out of scanning the Engine Control Module, you can bet that the Engine Control Module is not having a problem communicating. If it was, you would get a non-communication fault from your scan equipment and the ECM would not tell you anything. Instead, the ECM is telling on the module that is not communicating properly .
I like to call these codes the 1-800 codes...THE PHONE LINE IS DOWN... lol ;)
