Hello all,
Looking to get some assistance on a suspension issue. I am getting HDC inactive, Air susp. inactive. The air bags keep pressure and when I stop the car I can feel and see the car lower then raise. I used an ODB reader and there are no errors reported. I tried the turning the wheel all the way to the left then to the right and it did not clear the errors. I would like some suggestions on what to look for.

What diag did you use ?? If you have not cleared the hard fault it will not work properly until you do.

I used

iCarsoft LR V3.0 for Land Rover. brand new

The icarsoft is pretty good but I'm not sure it clears eas hard faults.

Do you have a suggestion of another one that will clear hard faults?

The gap id bluetooth will do it

except it may not be an eas problem, a faulty steering angle sensor causes same problem as does a wheel speed sensor

Thanks, I will look into this one. Is there a specific model, like the icar?

OK, I very green for Range Rovers and there is just so much to this car! I will look at into these.

forgot the battery when weak can throw up all sorts of problems

You really need to check all the ecm on the car not just suspension as a fault in any one of them can and will stop the suspension from working.

I know, but I don't have the OBD tool to test everything. I got the tool yesterday and i have a CAN Bus fault error. Thanks

Thanks, I just replaced the battery about two weeks ago, and had someone test the voltage and everything is good.

So, i got a ODB and tested everything. I have a couple of issues but the first is a CAN Bus issue with no codes. Everything I tested came back to a CAN Bus error.

Generic ODB reader is no good. You need L322 specific diagnostics.
