Have a 2005 LR3 with suspension issues, getting the "transmission fault, traction reduced" error, also "special programs unavailable", my suspension is stuck down on bumpers.

I have the IID Gap Tool, still very new to using it however

I have replaced the compressor with a new Hitachi one, I am getting nothing, no humming or anything, relay is new with part

I have tried utilizing the GAP tool to do a calibration on suspension, but when I go into the settings and try to perform this it says error failed?

I have replaced the terrain selection module and still getting same issues, cannot lift vehicle or select off road selections. I can switch into 4x4 low and switch back to 4x4 high with no issues.

I have performed a "hard reset" with no luck

I am getting a codes "U0132-87 "lost communication with ride level control module
"C1A09-1C" Pressure Sensor signal
"C1A11-65" Pressure increases when system inactive
"C1A13-64" Pressure does not decrease when venting gallery
"C1A36-01" Exhaust Valve - General Failure information

I have checked every fuse in the fuse area, nothing was blown and seems fine by visual

I literally do not know where to go with this, I feel like I am just throwing money at an electrical gremlin

Thanks for any help

Try jacking up the vehicle off the bump stops and see if it will pump up for you. Last time mine dropped I had to do that to get it to raise. I had different codes than you mention, but it’s definitely cheap, easy and a common issue. You won’t be able to calibrate until you’re sitting at normal ride height.

Was your out-going compressor a Hitachi as well? Or an AMK?
