Suspension, Brakes and Tires Discussion, 1993 Sts "service Ride Control" in Item Specific Cadillac Discussion; Bought this 1993 Seville STS last summer, after getting new tires the "SERVICE RIDE CONTROL" message comes on. How do ...
Check the codes by turning the key on, then pressing and holding the OFF and warmer (red) buttons until all of the displays light up. It will then go into diagnostics mode and start showing you the codes. Have a pencil and paper ready to write down the codes. When you get to "PCM?" you can either press the OFF button once to have it repeat the codes again or you can simply turn the key off to exit diagnostics mode.
What you are looking for is any code in the format of "S###". The S is for Suspension. Post the codes up here and someone will help you. You can also look the codes up here: http://myweb.accessus.net/~090/dtcobd1.html
I thought I would post back to this thread, as it was how I was able to get to the point that I am at know with this problem. I have the same issue, with the same year make and model car.
These are the codes that I am getting:
S011-Left Front Damper Solenoid Valve Short to Ground/Open
S016-Right Front Damper Solenoid Valve Short to Ground/Open
S044-Lift or Dive signal fault
S055-Resistor module short to ground
S073-Right rear accelerometer fault
I will start searching the threads for the fault codes but, thought someone might have a 50,000 foot view of the over-all problem.
from the 50000 ft view...check the connections at the towers, I only say this based on the OP's statment of "after I got new tires"...If some moron disconnected them for some reason (thought he had to for alignment?!?) that will start the code throwing. Also keep in mind if we are talking original equipment on a 16 year old car it could just be parts wanting to be replaced...
