Car Computer Failure

['Hamas' Jenkins]

Hi All,

I recently purchased a Mazda Tribute, and am actually going to pick it up this weekend. I got a call from the dealer this morning, who told me that the check engine light had popped on. They checked with the OBII scanner, and according to him, no error codes popped up, so they thought that it was an error with the computer. Thus, they swapped it out, but the new computer is showing the same problem, only it isn't displaying any error codes. Do you all have any idea what the problems may/may not be?

Thanks again for the help.
