Part # SWO500040 Install ABS Modulator Valve Kit On Discovery Series IIHi I'm Doug. Your tech support representative at Atlantic British. In this video we're going to talk about maybe the second step, or a better step in approaching getting rid of the 3 amigos on your vehicle. Now again we've stated any ABS fault is going to activate the 3 amigos which is essentially your ABS, your hill descend and your traction control lights on your dash. But, you use the fault codes to find out that in fact it is shuttle valve circuits that are creating the problem. Now everybody refers to this as shuttle valves which in essence it's not the shuttle valve itself but it is the shuttle valve actuator. And this is the 2 actuators that plunge and operate the 2 valves. In addition to that though, you have this intermediate block which also has all the solenoids that activate and pull the valves open on the system. Now what happens is should we get a little brake fluid in there, or just due to exposure, the 2 pin connectors inside that block which plugs into the shuttle valve actuator can get some corrosion on it, as well as the connectors here. So after inspection and you find you see some corrosion in there or you've pulled the shuttle valves apart and I know there are some test out there you can test these to determine if they are good or bad, that you may want to do the 2 piece set which we have as a kit. So you might want to look into that. What we're going to do is going to show you we've already shown you how to install the shuttle valve itself without disconnecting the brake lines. You can refer back to our video on that. But what we're going to do now is show you how to install this intermediate block. This also doesn't include removing the brake lines which you basically can get around. I'm going to show you how to do that. So right away you'll notice that the solenoid block doesn't have any hydraulic lines going to it. So we actually should be able to replace this without having to disconnect any of the lines. Before we do that though we need to lift this block so that we can unbolt the shuttle valve actuator underneath because that actually attaches electrically to the bottom side of this solenoid block. So first what we do is start off with push that tab and we pull the 2 electrical connectors. There's a little squeeze tab on the backside of this lower one. And that pulls that out. And get that out of the way. And even though it's really not necessary we'll take the brake fluid level connector off just to move that out of the way just so we know we're not going to damage the wiring. It's good to move that and get that clear. So you have 3 10 millimeter nuts. The back ones you'll need to remove. The front one is in a slotted hole so all we need to so with that is essentially just loosen it. And probably about 4 or 5 turns and that should give us enough slack to remove that.You can determine basically how hard they were to get out will help determine how much torque to put on them putting them back in. And generally I did it by hand and it works fine for me. But you may want to gauge how tight they are by how tight they were coming off. Alright just to finish things off you're going to make sure top put your 2 electrical connectors back on. Plug in your brake fluid level connector. And at that point you're done. You didn't brake the lines open so we don't have to bleed the system. You may want to clear the codes out of the ABS module. If you don't have that capability actually what it will do is, it won't necessarily clear the code, but it will keep the light off if it sees that the system is functioning properly at this point. If you should still end up with issues with the 3 amigos and they still come up as shuttle valve codes, then more than likely you're going to need the hydraulic unit. But we find for the majority of vehicles out there, this repair takes care of it. So when you're ready to take care of your shuttle valve issue, and you find you need the extra component that this kit will help fix it for you, just call any of our knowledgeable salesmen at 1-800-533-2210. And thanks for watching.
