1999 Volvo S70 Q&A
1999 Volvo S70 Question: I need a Drive Cycle to pass emissions?!?!?
So I had problems with my car stalling out due to draining batteries. I have had 4-5 new batteries in the last year and a half. I just replaced one a few days ago and went to emissions. I need a drive cycle before my car can even be tested! this is frustrating being my tabs expire at the end of the month. What do I do? There have been various sites online all saying something different and I don't have the $585 for a dealership to do it for me. What do you suggest? Thanks! - kimwin999
A good scan tool tells which monitors are passes and not yet completed. Some tests are checked and some require a two trip cycle. The Evaporative Emission test and Catalytic Converter efficiency test are the hardest to get to pass. The est criteria is difficult to duplicate, and impossible to duplicate in traffic. Sometimes if I know exactly which monitor is not passed I drive the car on jack stands to keep the road speed exactly where the manufacturer wants it to do the tests. I will show you a test used by Hyundai its crazy to try to duplicate but may help. I will send it to your email address. - patrick mannion
I have had the same thing all that means is you need to drive your car a bit to get drive cycle info in the cars computer so the testing equipment can see it. If the car has been sitting without a battery in it for a bit the information is lost and you need to replace it by just driving the car. I recommend a variety of driving like some fast start and stop and some freeway driving. Be safe but if you can speed up and decelerate to give the computer more info. Then drive in town with starts and stops. I'd give it a good 20-30 minutes worth at least - Quarath
