I have a 2016 LR4 with 65k miles on it. First land rover I've owned.
Im getting a "Normal height only" error that comes on when i try to change heights on my 2016 and ocassionally while i drive down the road.
It seems to ride, sit and drive fine at standard height. its not sagging at all.
i tired to reset the system by pulling the relay for awhile
Is there a good scanner tool on the market for suspension fault diagnostics?
i bought a Carsoft CR Pro scanner tool and the fault i got was U0421 Invalid Data Received From Suspension Control Module
Any advice or input would be greatly appreciated

 

Skippyghost,

Funny - I have the same problem with my 2012 LR4. No sagging, but won't raise or lower.

I bought a ICarSoft LRII and was able to read my codes. Mine is coming up with an issue with the rear left control valve.

The relay only powers the compressor as far as I know. There are a few fuses for the system as a whole.

You have a soft error. This usually caused by a faulty reading or inferred fault. You need to get the codes.

 

The fault code i got from a Carsoft CR Pro scanner tool was U0421 Invalid Data Received From Suspension Control Module

 

Odd, thats a comm fault but usually there are other codes that would come along with it. So it could mean anything, but essentially its saying that the control module told the system to do something and it did respond as expected. Like it told the vehicle to raise and it would not or such. So that one code is not really of much help.
