The problem is with the module controlling the active suspensions.

Often this are controlled directly from the Electronic Control Module, that is the car main computer.

To fix this you need to go to a qualified garage, and have the car computer tested with a scanner.

    Generally , from description, the pump for the air suspension is working. The strut is also fine.

    What you need to check and eventually replace is the control module.

It may be helpful for you to get some idea of the mechanism involved in operating the shock absorbers in your vehicle. Refer this information. It may then be a matter of finding the parts involved if replacement is required

The air suspention pump is not working


Use a test light to the air suspension pump to see if it is getting current. I assume that the rear end is sagging a bit as far as ride height, due to the pump not working. Also, may try to remove and replace pump, assuming that's the problem, and then when the rear air shocks pump up, make sure there are no leaks after shutting down the vehicle.

Also, make sure that the shut off switch for the suspension isn't flipped to 'off.'

My 92 seville is sagging in the back any ideas on


Yes doe's your car, have the air ride suspension if so you need to replace the air pump or the air ride shocks on the rear or look for a valve under the rear bumper or in the trunk to inflate the shocks.. if nowhere to be found then take your car, in to a shop.
Good Luck!

1998 Seville SLS, 42,000 mi, Limit speed to 90mph.


it mean that one of the electronic load leveling sensor is not reading. that sensor tells the air pump to fill up that air shock or air bag. the sensors maybe reasonable price wise but if the sensor is reading that an air shock is not holding air pressure and an air shock is not cheap.

1998 seville sts check suspension light stays on. New shocks on rear.


that system has a pump, you should hear it run when you start the car. it also has a bleed valve. i have seen the valve get stuck before. i don't remember what year caddillac stopped putting the suspension switch in the trunk, but if the switch has been turned off the light will remain on as well. there is a level sensor under the rear of the car connected to the suspension you can try to disconnect the arm and manually move it and see if the pump kicks on. there is a few second delay before you hear the pump. if the fuses are good and the switch is on check for voltage at the pump when you move the level sensor. check for signal from the sensor. if pump runs and shock don't air up check for air leaks with soap water spray, and/or air bypassing valve. hope i helped you...dustang
