Orange Error after ACE Pipe change
 

Hello guys,

I'm not a native speaker, so i would be glad if you would refrain from mistakes I made in my post. I had leaks in one of the ace-pipes traveling through the front right side wheel housing. At first i tried a hotfix with cutting ring fittings from my local hydraulics store (assuming 10mm diameter), which didn't shut the leaking, as the land rover pipe diameter in the end was some weird 9.74ish mm. I found some posts online of people who modified their ace-block to fit standardized hydraulic tubes/pipes, which i did as well with the help of my local hydraulics store. Now i got everything finished and refilled the ace surge tank with PSF, but the orange ace-car-spin-symbol-error is still there. Before my modification i would refuel the ace surge tank every now and then (because I still drove it while leaking), and the orange light would come on every now and then, following which i would step out and refuel instantly, which made the light go off again. So now I'm wondering is there anything I still need to do, like some special venting or such? From my understanding it should vent by just being turned on, or am i wrong? I added some pictures, just for the context... I didn't take pictures between every step. Can something happen if I'm just going to drive it? I mean there is liquid in the tank, the pump won't suck air, will it?

TL;DR I replaced the ACE pipes with custom ones - now orange error - what do i do

Best regards, and thanks for your helpful answers in advance,

Do you have access to a Nanocom? There may still be someone on the forum who rents one out.
I'm pretty sure that the Nanocom has a test regimen for the ACE system. That will tell you whether or not the system is working, regardless of what the light is showing. It should also be able to tell you what specific ACE error is causing the light.

Hi, thanks for your quick answer, I know a buddy with a diagnostics tool, is it important that it's a it's nanocom?

Most generic tools won't be able to read the codes from the ACE system, but it would be worth trying to see. There are some relatively inexpensive tools that will read all of the Rover's systems, and you really should own one if you're going to have a Rover. There are plenty of threads on here that discuss the different units that are available.
I think the Nanocom is the only consumer tool that has the testing facility for the ACE system.

Ok, thanks, I'll try it out! I ordered a cheap one with good overall rating for now, and my buddy will come over with his expensive one later today. If it doesn't work I'll go and order a nanocom. It should still be cheap compared to the ace pump.

Edit: costs around the same as the ace-pump

Hey guys,

After waiting for weeks so that my local Land Rover dealer would get the device to my city (they are a chain and have multiple shops, but only one device that can read the disco 2s ace) and trying out multiple cheap chine diagnostic tools I found a tool that can read everything from my disco 2, including the ace. It's called topdon artidiag800 BT. All the other ones and an expensive one of my buddy didn't work.

I'll add a screenshot of the report PDF:

does that somehow help you guys identifying something? I already tried swapping the pipes for pump in and out, but that didn't fix it. I also tried deleting the errors, which resulted in the orange light to be turned off until I drive a little faster again.

I'm glad about any help that I can get,

Best regards

The last code makes me wonder if the other errors are related to it. If the "main relay" for the ACE system is not functioning, perhaps the other systems will not work until that is fixed?

Thanks for your quick answer,

the main relay for the ACE system is the one in the front right, behind the battery, isn't it? I changed the ACE relay with the horn relay, the orange error persists. I can do the diagnostic scan again tomorrow with the horn relay. Is there any other "main relay"? I couldn't find anything else. The fuse seems to be good as well.

The RAVE says that R14 is the ACE relay; this is the right rear (looking from the front of the truck). Fuse 15 is also related to the ACE system so I would confirm/replace that as well.

Hi,

i switched R14 and R13, replaced F15 with a new one, also below the steering wheel F29 was replaced with a new one. After resetting the fault codes just now and driving more than 40km/h the RED error light now turned on :bow:

This is the screenshot of the (non-PDF) report right now, only one error:

Should i just swap the pump in/out (flow/return) again? Right now looking on the block i have: Bottom right = connected to pump (=> flow); Bottom left = connected to fluid-tank (=> return). I could not find detailed graphics of the correct connections in the manual, but I found in another thread and potentially other site(don't remember) that this should be correct (right = pump; left = tank). My notes that I took in the beginning where the other way round (right = tank; left = pump).

Could there be another reason for the error code?

Edit: This was the thread from another site that i found the info at:
https://www.lrukforums.com/threads/a...layout.140699/ The guy that drew with a pencil said right = pump; left = tank.

Edit2: According to this: https://www.lrukforums.com/attachmen...ge-png.144457/
The pump is connected to the pump is connected to the port with the high pressure filter witch is at the right side. So according to this I should have the right connection as it is right now...
