I can not get my 2002 Seville STS Cataylst to go into the Ready State for the OBDII Testing. The car (http://www.cadillacforums.com/forums/#) has no codes being generated. Car passed when last test was ran with with 75,000. Car now has 81,000 on it. I did a master clear of all the OBDII codes. They have all gone back to the ready state exect for the cataylst. I performed the recommended drive procedure to ready the cataylst and still no luck.
