Air suspension nightmare
Yup, a battery disconnect will clear em. Then you fire it up, drive it a bit and see what fresh codes come up. Then you have a better idea. Now if the same high list comes up I would put money a communications issues or such, even a faulty module on the CAN Bus can cause all sorts of havoc.
Parking brake faults dont cause any other hard faults as far as I know. So if the parking brake system is a mess, it should be okay to leave it for now. I had mine disabled for almost a year until I got around to servings and adjusting that system. I just pulled the fuse for it.

I do thank you a ton !!! Although it is certified and legal to drive, I really can't do that with a flat air suspension. But if clearing the codes get's me part way there, I'll be doing back flips in my driveway with my broken back !!
If I have no success doing that, I will order a warranty replacement for this compressor and try that. It may be a while before I come back with any news, but I will definitely get back to you.
Thanks again !!!

I have been running with a flashing red parking brake failure for a year. It makes no difference at all to the truck, just don't expect the parking brake to do anything lol
Such advice is idiotic OR...they will be behind you to swoop it up. The LR3 is a fantastic 4x4. Don't give up on it ....it's worth a couple G's worth of deferred maintenance.

I disconnected the battery to reset all codes. (I have nothing to read new codes with so no idea what codes are there now if any)
Still showing a suspension fault
Ordered in the replacement compressor and swapped that out.
compressor runs for a min or 2 and then stops, and yellow suspension light comes back on disabling special selections and the lock switch on the drivers side of the console by the control.
Checked for power and activation to the valve solonoid on the compressor, appears to be good. Checked the pressure switch and solonoid valve on the gallery
Appears to be working. Release air from the system and the amber dash light for the suspension goes off and then compressor will run again.
The light stayed off once and the special selector stayed on. Still no lift.
Played with the lock lift switch 4 or 5 times, and then the suspension inflated front and back to reg road height.
Got all excited, took the beast for a 10 min ride up the street and around a few blocks and back home. Still excited, until I get out of the beast and see the rear is squatted again.
15 more mins and the rear was slammed down again and the front stayed up all night.
Try as I might I can not get that trouble light to stay off and reinflate the rear.
Disconnected the battery and 25 mins later tried , No change.
Now, through all this, I seen 2 more issues on the display. But are not showing up now.
message 1 - Something about the height being in extended mode
message 2 - a message saying to clear any thing in the way and reset the suspension height.
There is a 3rd message saying special selections are not available or have been deactivated or something to that effect. But that one is pretty explanitory because of the fault.
Car sits now. rear slammed down, and front is raised to normal driving height.
Does this give us more to go on ?
No I do not, :-( That's another $1000.00 up here that I can not afford.
I feel safe in assuming the back dropped because of an air leak. But unless I can keep the air up, to test for leaks... I'm daft.
Unless we have a member here that can help me out with that, the only place around here that has a tool to read all the codes is the one that told me to junk the beast. Otherwise, they charge $120.00 / hr labor rate.

GAP Diagnostics is a Canadian company, in the list of fault codes i noticed 2 for the brake switch, one that said open circuit and the other failure so i'd replace the brake switch.
