![]() I still have yet to get the catalyst to set on 3 smart cars so far, but again it's not really distance but based on the quality of the drive and it has to hit a specific amount of drive cycles for it to complete. it compares calibration data with factory and checks your exhaust thru ur factory o2 sensor. California enacted a new smog test that went into effect mid 2014 which doesnt require the cars to run on a dyno and the sniffer tube stuck up it's exhaust, it's all based on more indepth reading into the OBD II port. The last one that takes the longest to complete is the catalyst converter, however it's also the one required in california to complete even though you may have one of the other ones incomplete to run the smog test. at the same time your HO2S, the heated oxygen sensor will also be running it's test after you take off. I would advice to not move the car for 2-3 cycles of this, it takes about 30 seconds for it to complete. You'll hear the air pump kick in for the secondary air readiness test. ![]() You will also need to complete a few cold start up where the intake air temp and coolant temp are within a few degrees of each other. I have yet to find the exact drive cycle for the smart car but this is based on experiences with other cars and the smart cars. It's not based on mileage but based on the quality of the drive.Įvap, secondary air usually completes with between 1/4 - 3/4 tank of gas, engine warmed up, and engine is decelerated without stepping on the brakes from approx 60 mph down to 30 mph. Each one of those test will complete after it follows a per set, pre programmed drive cycle. The readiness indicators are reset either when the battery dies or a check engine light is reset. The O2 sensors requires stop and go driving, to include some hard but NOT WOT accelerations from slow to faster speeds.I have 3 smart cars at my shop right now that needs to complete it's smog in california. O2 sensor isn't performed right away, usually EGR and some others are performed after fully warming up, but the O2 sensor is usually performed within 25 miles of driving. Look up the conditions, its usually the fuel tank level has to be between 3/4 and 1/4 of tank, more or less and it won't perform, the engine does have to be cold soaked overnight, and although they say its needs to be less than 60° (might be different for the WK2) I have still seen it performed in summer when morning temps were higher. ![]() I have seen that last test (evap emissions take more than 2 weeks before its performed and the test cycle is complete). I have only seen the Evap Emission Test remain outstanding more than a week or a 100 miles driving. The one exception is the Evap Emissions Test, which is usually last and requires some very specific conditions out of your control, like a cold soaked start in the morning under 60☏. ![]() If you do normal in town and highway driving it usually completes all the tests within 50 miles, maybe a little more sometimes, you have to do some stop and go driving as well as a highway speed steady cruise. So its possible to get the all the emissions test to initiate and complete within as little as 25 miles of driving, it sometime takes longer. ![]() The recommended Drive Cycle is to set the conditions for the test to initiate and complete. You do know that when you erase codes it resets the emission test status, so you may have been checking it while doing 140k miles of driving, but if you're erasing or reseting with the tool everytime you hook it up, you're reseting the emissions test status and starting from scratch each time. Are you assuming you'll fail emissions because of your cheap OBDII reader? Or you went to emissions inspection and they told you failed for the test readiness status not being complete?ĭid you ever think it could be your cheap OBDII reader? ![]()
