Customer Question

HI i have a 2001 bmw 525i, i bought it and didnt notice the check engine light was on, as its only visible during the night. I took it to get a smog check here in Las Vegas, NV and it failed with 9 codes. When i went to hook up a scanner it wouldnt even turn the scanner on so i couldnt communicate with the ecu on the codes. My questions are why is the service engine light so dim? why cant i get a regular scanner to communicate with my ecu? could there be a blown fuse?
