air suspension light comes on

[duderduderini]

Hi
I bought the RRS last thursday in Melbourne then drove it back to Albury Friday with no probs. It is a 2006 2.7 Diesel. My wifes dad passed away unexpectedly so we were off to Adelaide the next day. I debated whether to take the old car but took the Rangie untested. Things went well till Pinnaroo where I couldnt unlock the car with the fob (either of them) even though I could here the door lock solenoids working. After a 5 minute anxious battle they unlocked and off we went.
2 days ago after the first morning start up the orange suspenseion light came on for about a minute then went out. Didnt do it again until today on first startup where it cycled through test no probs then a few minutes down the road it came up red with the dont exceed 30 mph warning. It went out after 30 seconds or so never to appear again today.
2 things i checked today were the battery which looks newish with no date markings on it.. genbuine LR and I took the cover off the air compressor expecting to find a Hitachi compressor but found a very clean looking AKM instead.
My worry is getting beached on the way back to albury which is around 900 k's away.
I have taken out the relay and reseated it. Removed the relevant fuses, checked .them and replaced them in case oxidation may have been the culprit.
Does anyone have any advice as to what to do right now till I get home?
Lovely Machine incidentally, quite a relaxed drive.
Thanks
Nick

With the suspension at normal height, remove the 20A suspension fuse from the engine bay fuse box as this will prevent any lowering. Next, remove the 5A suspension system fuse from the passenger compartment fuse box as this will stop the repetitive messages telling you to slow down.

Hi. Do i do this with the engine off? Just to be sure I have identified fuse number 35 (@5 Amps) in the passenger compartment and fuse number 26 (@ 20 amps) in the engine compartment
Thanks Very Much
ps do the akm compressors have the drier issues that the hitachi ones do.. what maintainence do they need?
Regards

Removing the fuses with the ignition off may avoid arcing between the fuse blade and the holder contacts but only if valves were currently open, but not a particular problem anyway. If the vehicle is not prone to dropping without notice then best practice would be to have the ignition off.

The cause may not be a failing compressor but even the AMK can fail. Best to get the codes read and consider all possible causes. Perhaps the relay wasn't changed or the software not updated when the AMK was fitted.

Your fuse numbers are correct.

what I might do is run the car for a bit then turn off and remove fuses
I misread your first post and now understand re the passenger fuse box. fuse number 35 is described as Äir suspension ECU/Speed Variable steering""
I hope thats the one.
Where can I get a code reader?
Thanks again Graeme

I expect that removing the suspension fuses will also disable your variable steering, which I assume would default to its normal setting.

Anyone with an IIDTool (perhaps BT verson only) could read your fault codes but not suspension operation specifics as that function is VIN-locked.
