Wanted to inform people who were having problems with their factory air suspension in the Cadillac Seville and Deville sedans that using a 2.2 ohm resistor wired into the connections that ran to the shocks or struts will trick out the computer and turn off the Service Stability System light.
Actually you can use any resistor between 2.2 and 4.6 ohms and this will be enough to trick out the computer. Simply cut the wire at the shock and solder the resistor into the wire with one side going to each end of the two wires and wrap with tape real good to prevent corrosion. Tuck the wire and you are done! No more Service Stability System light and no more 100 MPH governor holding you back as a result!
You can pick up Monroes rear air shocks for under $100 a pair and use the kit to fill them up manually or make a trick setup to use the existing pump if you want to raise the rear end up without having to use an air chuck (just like when you fill your tires). Only problem with these inexpensive alternatives to the near $1000 each Cadillac rear air shocks is they don't have the sensors and this is why you have to use the resistors to trick out the computer otherwise you get the warning message on the dash along with the 100 MPH limitation.
Same goes for the front struts! You can buy a set of good conventional struts from Detroit axle for under $200 for the pair but you will have to trick the computer with the same resistor trick even though the front struts do not have provisions for air injection like the rears, but they do however still have the sensors. Be sure that your front and rear resistors are all the same resistance between 2.2 ohms and 4.6 ohms and everything will be okay... No need for them fancy high watt resistors they try and sell you either, any cheap old Radio Shack resistor wired into all four corners will be enough to trick out the ELC / ALC computer.
I have some photos that I plan on posting up soon!
