Good morning,

First, I would like to introduce myself – my name is Jacek.
I am the proud owner of a 2003 Land Rover Discovery 2, a lifted version. I have been driving the car for four years.
Last year, I decided that I wanted it to be eternal, indestructible, and resistant to everything. ;)
Therefore, I made the decision to separate the frame from the body and professionally preserve the frame in the best possible way. I found a contractor who agreed to take on the task for a reasonable price (in my opinion). He performed the job, disassembled, preserved, and reassembled everything. Everything would have been perfect if not for the fact that the ACE system stopped working correctly.

Here, I am reaching out for help and support.

Before the repair, the system was functioning flawlessly. The system is sealed, the pump is replaced, the filters have been changed, but unfortunately, the symptoms are such that the car behaves correctly when turning left, but when turning right, alarms go off, and the red warning light comes on. We have already replaced everything – a new block (used, but tested), a new computer (used, but tested), new valves, and we also replaced the level sensors and accelerometers. Despite replacing the parts, it didn’t help.
The system still doesn't work.
I am looking for support because I am close to abandoning this system and installing a manual one, but considering the huge amount of work the mechanic put in and the time spent, I would still prefer to get the ACE system working again.

Does anyone have an electrical diagram of the ACE system or any idea what might be the cause that it works fine when turning one way but not the other?

After swapping the cables/connectors on the directional valves, the situation is reversed: the error occurs when turning left, but it works fine when turning right.
It is probably the wiring, but we have no idea where to find it. I need support.

Best regards,
Jacek
