Hello all. After replacing F & R cat converters on my 03 Tacoma when I hook up the scanner I get a "No Codes" reading but when I check the I/M Monitor status I am getting a INC on the cat converter monitor. I have put over 500 miles on the vehicle since changing the cats. Smog Station won't even test unless the I/M monitors all read OK. What I need to know is what it takes to get an "OK" reading on my scanner for the I/M Cat Monitor. Anybody have a similar problem? Thanks for any help/advice you can give.
