Air Suspension Wont Go Back Up & 90 Celsior Suspension Ecu Wanted

Recommended Posts

After running through the fuses (rear set gadget fuse blew & playing around under the drivers footwell) it seems that my air suspension is no longer responsive in fact the air pump doesnt even make a noise

What we have tried so far..

Wired up the pump manually, runs!

Suspension ECU reset

Unplugged the harness for the Aftermarket height control swapping with the original harness!

Replaced the fuses & relay

Checked the standard Height Controller switch

At the moment im not really sure where to go next except for replacing the suspension ECU? Does anyone know if the LS400 Airbag ECU can replace the Celsior ECU? Also interesting is that the dash on the Celsior for the height control flashes "Normal" and is unresponsive to changes in the standard height controller!

If any has a 90 Celsior Suspension ECU for sale, consider it sold!
