When I change the battery ( or let it run down) All of the OBD II drive cycle readiness is lost. OBD II readiness is required to pass the emissions tests in Tennessee. Last fall ( after a battery change) It failed the emissions test after about 30 days of random driving and cost me $300 at the dealer to get it reset.
Is there a DIY drive procedure which will get the drive cycle reset??
How long should it take with random stop and go driving. I am aware that Volvo is somewhat of a challenge in this regard.[align=left] [/align]
