On the 2002 Cadillac Seville 4.6L V8 (VIN 9), the 2002 Seville owner manual identifies Continuously Variable Road Sensing Suspension as STS-only and says it displays SERVICE SUSPENSION SYS when the controller detects a problem. The matching 2002 Seville STS RPO F45 OEM service procedure uses an Electronic Suspension Control damper-actuator test, including C0577 as an intermittent-circuit example. The message or DTC does not by itself prove that the electronic strut hardware failed.
Common Symptoms
SERVICE SUSPENSION SYS message
Intermittent C0577 damper-actuator circuit DTC
How to Fix
Confirm that the 2002 Seville is an STS equipped with CVRSS RPO F45. Have a qualified technician retrieve the suspension DTCs and run the ESC damper-actuator output test. For an intermittent C0577-type fault, the OEM procedure commands the affected solenoid while the suspected wiring and connector are moved to isolate the circuit or component. Confirm the failed circuit or damper before replacing a strut; do not order a strut, install a passive-conversion kit or defeat the warning from this card.
