Hi All,

After having the ABS Module repairer + replacing it I had the OBDII codes cleared, drove the car for about 2 weeks and returned to the shop to have the emission inspection done but I was told that the drive cycle has not been completed.
Is there a special way of driving, or special sequence of things that has to be followed to complete the drive cycle?

Thanks Skip

 

I have never done a drive cycle in my Volvo(s) but I do it ever year on my GMC to pass inspection ( check engine light always comes on after climbing a hill). It takes about 2 hours to do the drive cycle on the GMC.

A quick search on came up with this for a Volvo 850 http://en.allexperts.com/q/Volvo-802...-Volvo-850.htm

 

Thanks Rick
