Hello, I have a 2003 Land Rover discovery that is throwing a rear right outlet valve circuit open code on my nanocom. My dashboard is now lit up like a Christmas tree with TC, ABS, hill decent you name it haha. It started off by only coming on every once in a while and shutting off when I restarted the car. Now it is stuck on after hitting a nice pothole. I have not addressed this fault yet as I have been busy but I was just curious if anybody has any useful information on what could cause this code besides something as simple as a loose connection or faulty sensor because I have read a number of different things with no clear answer. Thanks.

 

Sounds like you have the Three Amigos, along with the RR ABS sensor needing to be replaced.

 

It could be a shuttle valve seal is leaking. Repair instructions attached.

 

Are you sure about that? The ABS sensor is at the wheel, the outlet valve is in the modulator. To what does that error actually refer?

 

ABS errors often show up in strange ways. It looks like you have a Nanocom so it should be picking them up accurately, but the hard bump causing the error to set in place makes me think that a wheel sensor could also be contributing. I would start with the shuttle valves (and do Option B while that is being fixed) but I wouldn't be surprised if you need a wheel sensor replacement as well.
