Vehicle Dynamic Suspension — 2016 workshop reference 2611

Ignition OFF. Disconnect all VDM related in-line electrical connectors. 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 A8
No	REPAIR the connector or terminals. Refer to Wiring Diagrams Cell 5 for schematic and connector information.

A8 CHECK FOR CORRECT VDM (VEHICLE DYNAMICS CONTROL MODULE) OPERATION

Connect VDM C4585A and all related in-line electrical connectors. 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 Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new VDM. REFER to: Vehicle Dynamics Control Module (VDM) (204-05 Vehicle Dynamic Suspension, Removal and Installation).
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.

P0563:17, P1794:17

Refer to Wiring Diagrams Cell 41 for schematic and connector information.

Normal Operation and Fault Conditions

The VDM requires an operating voltage that is between 9 and 16 volts. The VDM receives this voltage from the BCM and has a single ground circuit. Excessive resistance or an open in one or more of these circuits, a discharged battery or a inoperative charging system results in the VDM setting a DTC.

An overcharging condition in the charging system results in the VDM setting a DTC. This DTC may also set in the VDM due to battery charging or vehicle jump starting events.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Conditions
	P0563:17 System Voltage High: Circuit Voltage Above Threshold	This DTC sets in continuous memory and on-demand if the voltage supplied to the VDM is above 16 volts for more than 3 seconds.
	P1794:17 Battery Voltage Circuit: Circuit Voltage Above Threshold	This DTC sets in continuous memory and on-demand if the voltage supplied to the VDM is above 16 volts for more than 60 seconds.
