Disconnect VDM C3672A and C3672B (if not previously disconnected).

Disconnect the suspect damper solenoid valve electrical connector (if not previously disconnected).

Using a good light source, inspect all disconnected electrical connectors for the following:
- corrosion - install new connector or terminal and clean the module pins
- damaged or bent pins - install new terminals or pins
- pushed-out pins - install new pins as necessary
- spread terminals - install new terminals as necessary

Are the connectors free of corrosion, damaged pins, bent pins, pushed-out pins and spread terminals?

Yes

GO to D8

No	REPAIR the connector or terminals. Refer to Wiring Diagram Connector Repair Procedures for schematic and connector information.

D8 CHECK FOR CORRECT VDM (VEHICLE DYNAMICS CONTROL MODULE) OPERATION

Connect the suspect damper solenoid valve electrical connector. Make sure it seats and latches correctly.

Connect VDM C3672A and C3672B . Make sure they seat and latch correctly.

Operate the system and determine if the concern is still present.

Is the concern still present?

Yes

CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no Technical Service Bulletins (TSBs) exist for this concern, INSTALL a new VDM module. REFER to:Vehicle Dynamics Control Module (VDM) .

No	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
