UZS131 air suspension problem

[triptek]

I'v got a problem with my uzs131 air suspension. All 4 corners of the car are on bumps stops. None of them will inflate. The compressor is running. Can't hear any air leaking near the wheels. If it was a leaking bag would the whole system not pump up? Any tips of where to start would be appreciated.

Soapy water in a spary bottle and soak every thing and look for bubbles

if tis anything like the soarers the common problem are the bags leaking or where the plastic hoses join together in the fittings
try jacking one end up with engine running and see if that helps start it to rise
also on the soarers there is a big switch to turn suspension off in the boot
also try removing a hose to see if the compressor is pumping
I have had to change a compressor on a soarer but u said u can hear it so prob not this but best check to see if its pumping

triptek, try this. Engine running, cycle between high and lo settings with the switch. alternate between cycling the TEMS on off and the air high low. A slight lift on the body might help get a bit of movement into the sensors, don't fully raise the car, just be aware that once the struts are fully extended the sensor is telling the bag ECU that the bags are fully inflated, consequently the air flow to those bags will be switched off.

dumbass, there is no isolation switch,

Removing the negative terminal from the battery for a few minutes resets the bag ECU.

They also won't raise if the battery volts is below 12 volts .

Damn good point Dave. I had no end of trouble with one of my Crowns, and it was simply that the Aus spec batteries terminals were a tad smaller than what the Japanese cable ends required, did not pick it up for a bit but the range of low voltage problems it caused was staggering, including intermittent bag operation.
