A conversion from the Nanocom reported code to the actual fault code would be useful.

How high does the rear go before the error occurs - to normal height or just a little?

The back doesn't go up anymore. I used the nanocom to empty the air tank and now the compressor only fires for a few seconds and cuts off giving me the suspension error

Here is a list of the faults after I did a hard reset..

FAULT 1 OF 5
ECU: Transfer Case
CODE:U0132
Lost communication with ride level ctrl module / Lost communication with suspension ctrl module A
(INTERMITTENT)

FAULT 2 OF 5
ECU: Ride Level
CODE:C1A75
Rear right height sensor mechanism
(INTERMITTENT)

FAULT 3 OF 5
ECU: Ride Level
CODE:C1A27
Compressor circuit
(INTERMITTENT)

FAULT 4 OF 5
ECU: Ride Level
CODE:C1A00
Control module
(PERMANENT)

FAULT 5 OF 5
ECU: All Terrain Control
CODE:U0421
Invalid data received from ride level control module
(PENDING)

Did you take the llams out of the circuit as suggested by Graeme ?

Yeah, llams is out of the circuit

Someone wiser than me will need to comment methinks.

Looking at those, gut feeling is that number 4 is the real issue and that the others are a factor of that. At a guess I would say check some of the connections to the xfer case module behind the battery, but that's just a guess. Sorry I can't be more enlightening

I've done another reset of the system and now getting these faults.

FAULT 1 OF 3
ECU: Ride Level
CODE:C1A00
Control module
(PERMANENT)

FAULT 2 OF 3
ECU: Ride Level
CODE:C1A00
Control module
(PERMANENT)

FAULT 3 OF 3
ECU: All Terrain Control
CODE:U0421
Invalid data received from ride level control module
(PENDING)

At least the list is getting smaller

So it appears that the back was raising using the reservoir rather than a problem with the front.

Check the 5A suspension system fuse in the engine compartment fuse panel. This fuse is in the circuit from the compressor relay and is used to confirm that there is power to the compressor from the compressor relay and if its blown then the compressor will only be allowed to run for a second or 2.

I changed out that fuse and the compressor runs for about 30 seconds now but with no change in the height of the car.

I believe when the back was rising up and down it was getting a signal from the llams unit to do so. There was air in the tank at that stage, but I emptied the springs and tank using the Nanocom. Do you think I need to replace the compressor?
