Ford Motors Drive Cycle Readiness for Smog Check

You can either use an OBDII scanner or, if one is not available, check the MIL (check engine light). Generally car manufacturers will, on vehicle startup, indicate the status of the readiness monitors are set. (Note: At A Star Smog, we will use an OBDII scanner to conduct a smog precheck).
