1999 Seville SLS Service Stability System - 7/2/2008 9:01:44 PM

When I go over a bump in the road the service stability systems comes on the dash, the abs lights up and the traction control light comes on. I notice the car sitting low in the back and don''t hear the air shocks pump. When I turn the car off an on it resets until I hit another bump. I did take it to cadillac once but it was very intermittent then, now it always happens. I know it had 3 codes in the history but I do not remember what they were. I think I have a bad shock, how do I tell which one is bad. Also where can I buy replacement shocks at a reasonable price. The next time it happens I can take it to auto zone and have them give me the codes. Please advise on how I should proceed.

Thanks

I just had the computer scanned and the following codes are showing during the failure, C1223, C1227,C1234. I am going to replace the left rear hub assembly.

My rear shocks are leaking as soon as I go over a bump the service stability system comes on. If I put 160lbs of salt in the trunk the service stability comes on. I guess I have to replace the rear shocks. But i may have more probles as the abs comes on and traction control I had the Rear BCM scanned and once it had some left rear speed sensor codes. I don''t know what to do , any suggestions.
