Perform CVRSS system check. See CVRSS SYSTEM CHECK . After performing CVRSS system check, go to next step.
If Code C1786, C1787 or C1788 is set, go to applicable code for diagnosis. See CODE DESCRIPTION table under SELF-DIAGNOSTICS. If Code C1786, C1787 or C1788 is not set, go to next step.
Turn ignition off. Disconnect damper actuator connector. Using DVOM, measure resistance between terminals of damper actuator connector (component side). If resistance is 9.5-15.5 ohms, go to next step. If resistance is not 9.5-15.5 ohms, go to step 7).
Check continuity between damper control circuit (Gray wire on front; Dark Green wire on rear) of damper actuator connector (component side) and ground. See WIRING DIAGRAMS . If continuity exists, go to step 7). If continuity does not exist, go to next step.
Disconnect 32-pin CVRSS control module connector C3. Check continuity between damper control circuit (Gray wire on front; Dark Green wire on rear) of CVRSS control module harness connector C3 and ground. See WIRING DIAGRAMS . Repair as necessary. After repairs, perform CVRSS SYSTEM CHECK . If circuit is okay, go to next step.
Check for intermittent shorts or chafed wires. Turn ignition off. Reinstall/reconnect all components/connectors. Turn ignition on, with engine off. Clear codes, and then wait 90 seconds. Display codes. If Code C1711, C1716, C1721 or C1726 is set, go to step 8). If Code C1711, C1716, C1721 or C1726 is not set, perform CVRSS SYSTEM CHECK .
Replace damper actuator. After repairs, perform CVRSS SYSTEM CHECK .
Turn ignition off. Replace CVRSS control module. Reinstall/reconnect all components/connectors. Install scan tool. Turn ignition on, with engine off. Calibrate NEW CVRSS control module. See CALIBRATING CVRSS CONTROL MODULE under ADJUSTMENTS. Perform CVRSS SYSTEM CHECK .
