are you flashing the codes by watching the dash light or using a code reader.code 12 is the indicator that tells you the code sequence is starting and code 55 is the indicator code that tells you its the end of reading the codes.if you don`t have any codes in between then you have no codes in the computer.
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 ;)
call autozone or orielleys or advance and tell them that code nd they will tell you what that code means, if u got the code from a code reader that u plug into the car thru and obd 2 reader then they can tell u
Did you have the computer checked to see what code or codes come up? If not and you have an Advanced Auto store near by they check computer codes for free. They hook up their code reader and it shows the code or codes and lists what the code means.
This code is simply telling you to checkfor transaxle codes. if they tell you that the TCM is bad . They are wrong. you need to get a special code for the transaxle. Sorry, but thats all the P0700 code means.
