Install EAS Reflash Module On Range Rover Sport 4.4 Or Land Rover LR3
In this video, Doug, our Land Rover Master Technician, will go over the installation of the re-flash module to remove dashboard codes after installation of our
coil suspension conversion kit L319SRK-OMEHL on our 2006 Range Rover Sport 4.4 (non-supercharged). This same install process also applies to the Land Rover LR3. Part #:7980 EAS Reflash Module Installation Demonstrated On Range Rover Sport Supercharged (Works On LR3) So when you're done converting your Sport or LR3 over from air suspension to coil spring, you're going to need to do what's referred to as a reflash, or inline filter. Basically to fool the system so that it will turn off all the warning lights, and the bells and whistles and everything. And everything else will operate. What it also does is it also maintains Terrain Response so you don't lose that. Which is nice. The only thing you do lose is the ability to raise and lower the vehicle at will. So, essentially what you'll be receiving is an EAS reflash unit. Refer to this. it's the 7980. It comes with the box. You'll also have a plug in pigtail. It's got 6 wires off of it that will need to be wired in. We're going to show you how to do that in a few minutes. And that's essentially it. And then through a small process you'll be able to reflash this unit so that you'll be able to drive away without having all the warning lights on. So we're going to start off with showing you how to access and where the location of the right lower control module is because the wiring going into that module is where we're going to be cutting into, and splicing into to make this work. All right, so we have the vehicle started. And you can see the warning lights you have on. Red brake light. The ABS light. The steering angle sensor. The suspension light. And all those are related, especially on these newer vehicles with these networks. They all talk to each other. So, now you've seen the lights. Now we're going to show you the Terrain Response, which the lights are out because it also sees a fault there. All right, so, here's your Terrain Response selector on the center console. And you'll see I'm going to move this bright light away just for a second, and you can see there are no indicator lights on that. So you've essentially lost Terrain Response. And we're going to go through the reflash and get that back. So to get started we're going to need a few basic tools. A straight blade screw driver. Phillips screw driver. I would prefer you use a nylon trim tool as opposed to metal. And then a quarter inch drive ratchet extension. This is a 10 millimeter deep swivel head. You can go with a regular deep with a shorter extension. This is just the set up I like to use. And an 8 millimeter deep quarter inch drive socket. So you start off with taking a straight blade and we're just going to stick that underneath that. This is your foot rest. This pops right off. Now, what that does is that exposes to 10 millimeter nuts that are going to hold this foot pad in place. So we grab our quarter ratchet. And the reason I go with the deep is because you've got probably about 3/4 of an inch of stud past the nut, so a regular socket will be a little to shallow to get all the way on the nut to get it off. So we've got one. Also, 1 more tool you're going to need is going to be a T25 torx driver. There's a torx head bolt that holds the hood release level on.Okay, so we've got one fault that's activated. Directional Stability Control, the Terrain Response is on which is good. And we're in coil mode because our lights here are out. So let's clear out the codes and double check and make sure everything is good. All right, so in many cases, even though you saw where Terrain Response was on, we had some codes that were showing up on here, essentially we did 2 or 3 restarts, and the vehicle actually cleared the codes out all by itself. So I have no warning lights on. We have Terrain Response. We have our high-low management here for our transfer case. And you'll notice that no lights here. It tells you that we are in coil mode. So we're actually good to go. So we're going to find a nice spot up in that upper area. We'll wire tie the box so that it's not hitting anything or rattling around under the dash. And it's simply just reverse your process for reassembly, just the way you took it apart. Once that's done, you're ready road test this and take it for a ride.
