Air suspension pump testing.

Ok, there's some good new then, if it's self levelling you should be able to hear the valves opening but at least they work! along with the exhaust valve.

So possibly the inlet valve is stuck/broke or it's back to the pressure switch.

Meanwhile I'll have a trawl through the Rovacom forums :wink:

Right had ago with the paper clip on the pressure switch and still nothing..
I left pump connected to battery for 6min and still nothing (as in height)but I did hear slight ticking from the valve block(approx 2ticks per second).

I drove it to my nearest petrol station on the bump stops to fill with air(my tyre pump not working now,tut,just my luck)and it hardly went up an inch.But where did all the air go I put in... :?:

My neighbour works for a commercial firm and said I can pop there in the morning to try put some proper air in it :)

I did try opening/closing the door with the inhibit switch on and it didnt self level but that might be because it were low anyway..

I'm determined to get this sorted and not convert to springs..... :(  :wink:

The inhibit switch on? if it's in the centre it's off, if it's down then it's on.  All it does is mimick a door being open.  Put it in the centre if you havn't tried that already, then when you shut the last door it should self-level (ignition off) but I guess you know that.

Once you have pumped it up you say it goes down due to a slow leak, which corner out of interest.  If you leave the inhibit on overnight you will see the offending corner sink to the floor.

Anyway, assuming the pump isn't goosed (a possibility) then there must be something else inhibiting the EAS.  The brake light switch is another suspect.

Hello again RRB...

I managed to get it off the bump stops today and as I was pumping it up at the front drivers side(with the inhibit switch in the centre position)the car self levelled when the front got to a certain height with air being sent to each air bag.
So didnt need to pump up from the rear.

As the door was open/closed the car levelled itself with the ticking from the valve block auditable.
I'm happy the self levelling side works fine.

There just doesnt seem to be any life going to the pump or the pressure switch(which I tried again with the paper clip to no avail).

If left overnight with the inhibit switch in centre pos it levels itself as it should every few hours and goes down level.
If left overnight with the inhibit switch down the rear is close to the bump stops in the morning.

Been driving it around all morning with the inhibit switch down/off and it been fine..

Could we be getting somewhere :?:  :lol:

Range Rover Blues:
Yes that sounds very encouraging, particulary that it 'found' some air in the tank to raise the back end and that it was able to raise under ECU control, that's all working.  The inhibit switch is just fine too.

This must have come from the tank, there is no way that air from the front bags can get into the back unless you are using a Diagnostic, so that must have been in your tank.  Sounds like the pump is doing it's thing when you connect jump leads to it.

So we still have no power to the pump, and it sounds like no power to the pressure switch (obvioulsy you found it, where was it?) did you check that with a test lamp or a meter?

I'm going to have to get a circuit diagram out and look at it now but it's going to be something silly, you'll laugh when you find it I'm sure :wink:
