Hi guys, I have LR3 2007 V8 and its been giving me this fault ,HDC fault ,system unavailable suspension lowering, not able to adjust it and a very unconfortable ride, I already replaced the battery with the original one, replaced the brake light switch and the fault is still there, dealership has no idea whats wrong with it, and i dont know what to do anymore, anybody has any suggestions or had this problem before, any comment would be appreciated
thanks

 

I would be looking at the Terrain Response module, and wiring directly below it. Seen several that have had something spilled on them in the past that start to fail down the road.

If your dealership cannot figure this out, you need to find a more qualified place to have your truck serviced. It is not that complicated of a system.

 

Thanks roverguy7, for sure i need to get a more qualified place for the truck, I will look into the Terrain Response module as you said, do I need to replace that module or just clean it?

 

If there is corrosion inside the module, on the PCB, you probably won't be able to clean it effectively, if it is just in the wiring or connectors, then clean them up, and as long as the pins weren't damaged it should be fine.

Check the big grey and green harness connectors inside the console as well.
