Quick Tip: COP Ignition Test

Applies To: MODIS Edge™, MODIS Ultra™, TRITON-D8®, VANTAGE® Legend, VANTAGE® Ultra, VERUS® Edge, VERUS® PRO, ZEUS®

Vehicle: 2013 Lincoln® MKZ. There are many different options out there for testing vehicles with Coil-On-Plug ignition systems, aren't there?  In this Diagnostic Quick Tip, National Field Trainer Jason Gabrenas shows you how to set up and use the universal flag pickups.



When it comes to testing ignition systems there's a whole lot of different options and ways to test it and things that you can use to test it on.

One of the options is these flag pickups here. They're pretty universal. They work with anything that's on a coil on plug vehicle, they come with a single and a triple and you can string them all together.

Also to use them, you need to use this single cylinder ignition adapter as well, so let's just go through, and show you how to hook these things up.

These have two different sides, one side to increase the signal going to the scope and one side to decrease the signal going to the scope.

So you can just start off with whichever side you like and set them on top of the coil here. You can usually secure it using the wire and then we can add in any number of extra units to get however many coils we have on the vehicle.

Depending on how you have it set up, you may also need to use a dual female to female RCA to RCA adapter. So you can just plug those two together, and then we need to ground it so we're going to ground it right here.

And lastly, I'll back-probe this coil here as a reference to know where my cylinder one is. So I have the scope all set up here; Channel One set for ignition and channel two I have probed into the number one coil, so I know where number one is in the firing order.

Firing order is one, three, four, two, and then you see one repeats there again. So we can chain these flags together. If I had a vehicle come in with a 16 cylinder, I could still do this and use this setup. You just have to keep adding more flags depending on how many cylinders you have.

So it's a pretty universal way to check ignition.
