    I know there are threads in here about it, I've seen them, but I can't seem to find one now. 09 T660 has check engine light but I can't seem to clear it. Anyone remember how?

    I've been trying to get back in here, but fir some reason I could never get the PW reset to actually reset. Finally got it to work, so... guess who's back?
