99 Contour Smog

All,

A friend of mine has a 99 contour. He can't pass smog because the smog machine can't bring up the history or read any of the sensors. Is this a computer problem? Any Ideas?

Thanks,

Rick

Sounds like the data link is down.. BUT: Suggest he take it to a parts store that reads out codes for free and see if they can read it.

If so, then he has a claim that it's not his problem to fix.
