Hi all... I am having a problem with the suspension on a 2010 full size RR. when vehicle is started the lights on the EAS controls light up and go off and "Suspension Fault" appears on the instrument cluster Vehicle front is lower than the rear, all fuses and wiring to the rear and front valve blocks are good, swapped valve blocks with known working ones, same fault, swapped center console and still same fault.
Fault code present U3000-1D RLM Control Module.
I have checked wiring looms, manually bypassed the compressor and works ok, checked voltage drops between valve blocks and control module. 0.17v voltage drop recorded.
replaced the EAS with a new module and programmed with LR approved diagnostic. Unable to calibrate ride level as vehicle height conrols are being disabled.
Ive been at this fault for 10days now and no information on forums relates to the fault. any help will be greatly appreciated.

thanks

 

I have a 2010 RRS with this exact issue of suspension fault and just U3000-1D code. Did you ever figure out what it was?
