I recently saw a post on a Disco 2 Facebook page that mentioned an earth / ground that is located under / behind the glove box near the ABS slab. Im currently battling the 3 amigos and an emergency brake light that stays on during operation. Can anyone shed some light on where exactly this earth / ground is? Also, so far, the shuttle valve, front left, and front right ABS wheel sensors have been replaced. I've done the bypass. However, I have since reverted it back to normal when I bought the new shuttlevalve since there was no luck in the fix. I'm about to move in the next 6 months and plan to sell; I would like to get everything operating properly prior to. Any help would be greatly appreciated. I've searched many threads with little luck. Brakes have been bled, brake lines replaced with steel braided, new master cylinder. Thanks in advance for your time.

 

It sounds like you are just replacing parts without properly diagnosing first. Get the transmission codes read to find out exactly what is causing your amigos and then act on that info.

 

Although I appreciate your time, that was not helpful at all. You may assume I am just replacing parts, however, these replacements were done over time and in response to issues encountered (other than the ABS sensor). The nearest place to get the transmission codes ran is a 30 min drive through the mountains (probably not the best place to have a brake failure / issue). So here I am, requesting assistance / inputs from those who may have experienced this issue. Thanks.

 

I didn't assume -- I said that's what it sounds like. But some of the actions you describe, such as undoing the shuttle valve repair, indicate that you may not have had accurate information about the cause(s) of your problem before attempting to fix it/them. That is, why did you do the "bypass" (assuming you mean Option B here, but perhaps you did something else) if you didn't know that it was what needed to be done?
In any case, the D2 electrical library provides the following information about the ground points you are looking for. Yes, the photo is from a RHD vehicle but the wiring layout should be the same.

 

The initial bypass was done because the shuttle valve was corroded to the point where wire insulation was non existent. Oddly enough, after testing the function of the switch itself, it seemed to be operating correctly. I did the bypass, and no joy. Electrical is BY FAR my weakest skillset for sure. If I'm understanding this correctly, there should be a ground on the inside of the vehicle behind the gas and brake pedals? What I should have mentioned in the original post is that the previous owner did some wild stuff with the wiring of this vehicle. Including quite a few less than sub-par connections / relocation of things (grounds). All of this combined has been a nightmare to get everything properly functioning. I live in Hawaii so the "island beater" mentality was unfortunately the case with this vehicle. I refuse to short-hand someone so I want to ensure that when I leave, I'm selling a reliable vehicle. To make matters worse, the nearest LR dealer is across the island and if im being honest, a dealer in Hawaii is the last place you want to go unless you're ready for a very painful quote. All of that to say, I am 100% not a millionaire so I'm doing what I can with the knowledge I hhave and asking for guidance along the way.

 

NO. Not behind the gas and brake pedals -- unless you have a RHD vehicle.

 

Okay so the ground locations are the same. So for my LHD vehicle, it should be located right on the under the the glove box on the back wall. That's where I initially looked and there wasn't one, however, I did see some half a**ed grounds on the metal framing behind the glove box. Typical stripped wire wrapped around a screw. Im going to relocate that back to the body of the vehicle and see if that does anything. The previous owner also installed a push to start that has given me quite a few issues as well. With that comes an entirely ineffective "alarm" that seems to just be shoved behind the dash. As previously stated, this DII has a lot of issues. I've been slowly trying to get after them one by one. The Ebrake light stays consistently lit as well. Fluid is good, e brake functions and disengages properly, and I've looked at the switch on the handbrake itself and it seems..... okay. Gotta start piecing that together as well. To say this vehicle has been a constant source of stress and issues would be the understatement of a century. I appreciate the help and your time, though.
