I have a 2014 LS460. Before getting the car smogged I had disconnected the battery. That was 130 miles ago. I run my obd scanner and it says it will fail because the Evaporative system has a warning. It says "vehicle has not completed this test. I know on my LS430 that if you disconnected the battery you had to drive about 60 miles for all the smog related computers would be ready to pass smog.
Anyone have any insight on this?

 

I believe, general guidance is around 100-200 miles. Lights can be set off at any point and not at certain mileage.

 

Thanks. Apparently you have to have 1/4 to 3/4 tank of gas and I've kept it full so I'll go for a drive and try that.

 

If I am not mistaken, Techstream allows active testing of certain sensors. It eliminates a need to drive for 100 miles before you know if the problem was fixed. I would suggest to google for related content and see what you come up with.

 

Are you getting the same code as you’d get with a loose gas cap?
