How to Check Readiness Monitors - Emission Inspection

Hey, everyone. Sue here from 1A Auto, and today we have a 2013 Camry in the shop and we have the battery disconnected because we did some engine work on it. When you happen to disconnect the battery, you clear all monitors, and monitors is what sets the perimeters on the computer in the car, the PCM. We actually happen to have to go get a sticker on this, so maybe you've run into it where someone said to you, "Everything looks good but the emissions didn't pass because your monitors weren't ready." Well, that's what we're going to talk about.

We have our little scanner here that we sell on our website. It's nice palm reader. It's a code reader, but it does a little bit more things than that. It doesn't do heavy diagnosing, but you use this and get this if you work on your own car, and you can check and see if your monitors are ready before you go waste your time and go to a shop for a state inspection after you've had a battery disconnected.

Some cars vary anywhere from 20 miles to 150 miles before those monitors reset, so with this tool, you can pull codes, but you also can check and see if the monitors are ready to go. So with no delay, let's see how it works.

So the DLC connector on most cars, if not all cars it's connected over underneath the drivers side. And on this Toyota it happens to be right here. Hook the 16 pin up, and you put your car on just ignition. I'm going to shut the door probably, because we don't want to listen to the radio, or maybe we do. Might be more entertaining than me. So now we have this hooked up, and see how it says DCDTC look up tool, or help. Well I'm going to highlight the green and just go with that.

It automatically starts checking all your monitors on this little launch tool. It's so self explanatory, you don't even have to worry about it. First thing it does for you is pull up your monitors. So there we have no engine light on because it's off. DTC's in the ECU, which is the computer. There's none. Readiness completed--there's eight completed. Readiness not completed--there's zero. And then there's readiness not supported--that could be anything from a heated O2 to a misfire code. There are no codes, so there's two monitors that you do not need for emissions. So we're all set.

I'm ready to go down to the inspection station and get a sticker.
