Code RS0013, 0018, 0023 & 0028: Damper Solenoid Valve Short Across Load

  1. Clear codes. Using scan tool, select RSS OUTPUTS, and then RS 002 (LF STRUT), RS 001 (RF STRUT), RS 004 (LR SHOCK) or RS 003 (RR SHOCK) for damper solenoid being tested. Cycle damper solenoid for 20 seconds. Display codes. If Code RS0010, RS0015, RS0020 or RS0025 is set, go to Code RS0010, RS0015, RS0020 or RS0025 for diagnosis. If Code RS0010, RS0015, RS0020 or RS0025 is not set, go to next step.
  2. If Code RS0013, RS0018, RS0023 or RS0028 is set, go to next step. If Code RS0013, RS0018, RS0023 or RS0028 is not set, go to NOTES ON INTERMITTENTS  under SELF-DIAGNOSTICS.
  3. Turn ignition off. Disconnect damper solenoid connector. Using DVOM, measure resistance between terminals of damper solenoid connector (component side). If resistance is 1.7-3 ohms, go to step 5). If resistance is not 1.7-3 ohms, go to next step.
  4. Replace damper solenoid. Check for short to voltage in Light Blue wire or Dark Green wire, and short to ground in Gray wire or Purple wire. Reinstall/reconnect all components/connectors. Clear codes. Using scan tool, select RSS OUTPUTS, and then RS 002 (LF STRUT), RS 001 (RF STRUT), RS 004 (LR SHOCK) or RS 003 (RR SHOCK) for damper solenoid being tested. Cycle damper solenoid for 20 seconds. Display codes. If Code RS0010, RS0015, RS0020 or RS0025 is set, go to Code RS0010, RS0015, RS0020 or RS0025 for diagnosis. If Code RS0010, RS0015, RS0020 or RS0025 is not set, fault is no longer present.
  5. Turn ignition off. Disconnect 8-pin RSS control module connector C3 (24-pin RSS control module connector C2 on right rear). Check continuity between terminals of damper solenoid harness connector. If continuity exists, go to next step. If continuity does not exist, go to step 7).
  6. Locate and repair short between Light Blue wire or Dark Green wire, and Gray wire or Purple wire. Reinstall/reconnect all components/connectors. Clear codes.
  7. Check RSS control module connector and damper solenoid connector for debris or corrosion. Reinstall/reconnect all components/connectors. Turn ignition on. Clear codes. Check RSS control module connector and damper solenoid connector for debris or corrosion. Reinstall/reconnect all components/connectors. Turn ignition on. Clear codes. Using scan tool, select RSS OUTPUTS, and then RS 002 (LF STRUT), RS 001 (RF STRUT), RS 004 (LR SHOCK) or RS 003 (RR SHOCK) for damper solenoid being tested. Cycle damper solenoid for 20 seconds. Display codes. If Code RS0013, RS0018, RS0023 or RS0028 is set, go to next step. If Code RS0013, RS0018, RS0023 or RS0028 is not set, go to NOTES ON INTERMITTENTS  under SELF-DIAGNOSTICS.
  8. Replace RSS control module. Calibrate NEW RSS control module. See CALIBRATING RSS CONTROL MODULE  under ADJUSTMENTS.
