  1. Perform RTD diagnostic system check. See RTD DIAGNOSTIC SYSTEM CHECK . After performing RTD diagnostic system check, go to next step.
  2. Turn ignition off. Disconnect left front damper solenoid connector. Measure resistance between solenoid connector terminals (solenoid side). If resistance is 9.5-15.5 ohms, go to next step. If resistance is not 9.5-15.5 ohms, replace damper (shock absorber). See SHOCK ABSORBER  under REMOVAL & INSTALLATION. After repairs, go to step 6).
  3. Reconnect left front damper solenoid connector. Disconnect RTD module connector C2. Check for continuity between harness side of RTD module connector C2, terminals D12 (Gray wire) and D13 (Light Blue wire). If continuity exists, go to next step. If continuity does not exist, locate and repair open in Gray or Light Blue wire between RTD module and damper solenoid and go to step 6). If continuity does not exist, go to next step.
  4. Check left front damper circuit for intermittent malfunction. Using scan tool, cycle left front damper solenoid while moving wiring and connectors. If intermittent malfunction is found and repaired, go to step 6). If intermittent malfunction is not found and repaired, go to next step.
  5. Turn ignition off. Connect or install any connector or components that were disconnected or removed. Turn ignition on. Using scan tool, clear all DTCs. Cycle left front damper solenoid for 60 seconds. If DTC C1712 is set, replace RTD control module. See RTD CONTROL MODULE  under REMOVAL & INSTALLATION. After repairs, go to next step. If DTC C1712 is not set, system is functioning properly.
  6. Turn ignition off. Connect or install any connector or components that were disconnected or removed. Turn ignition on. Using scan tool, clear all DTCs. After repairs, perform RTD diagnostic system check.
