Hello,

About 3 weeks ago my 2005 LR3 SE wouldn't start after a day of running errands. I first replaced the starter and that didn't fix, so I then traced the no start issue to the mega fuse linked to the positive battery terminal cable. After replacing the fuse, the LR3 cranked right up but now gives a 'Suspension Fault' and also 'Special Programs Not Available'. This is an issue because since the 3 has been sitting for 3 weeks now, all of the air has been drained from the suspension and it is sitting low.. on the bump stops.. so I am unable to drive it. I don't hear the compressor kick on to fill up the airbags. I've had the battery tested/charged at the parts store to rule that out. Any tips on how to reset the system fault and raise the 3 back up would be appreciated.

Edit: I've had no previous problems with the air suspension until this. If the 3 sits for a week or so, some air does leak out and it sits lower. But every time I start it back up the bags fill right back up.

If it has lift rods it's out of tolerance and you need to jack it up a couple of inches and it will fill up. I thought that was stupid a few weeks ago when I had the same issue but by golly it worked.

As far as clearing the fault messages you can’t disconnect your battery and let it sit for about ten minutes or so. Then you can hook the negative and positive battery cables together with a small copper wire and leave it for about five minutes or so. Then the truck should do a hard system reset that should clear all the fault messages.

So sorry about the typo meant to say you can disconnect

OK for what? To clear faults? I don't think so.
