REPLACE REMOTE TRUNK CLOSING CONTROL UNIT

This Service Campaign has been initiated because DCAG has determined that on the affected vehicles with remote trunk closing (SA Code 881; see VIN range) the remote trunk closing control unit may not be sufficiently durable and may result in the need to open and close the trunk manually. Dealer will replace the control unit.

Please review the Effective Serial Number chart located below, and, if necessary, repair the subject vehicles during the vehicle's next service.

Prior to performing this Service Campaign:

^ Please check VMI to insure the vehicle is involved and to determine if the vehicle has been previously repaired.

^ Please review the entire Service Campaign bulletin.

Approximately 1551 vehicles are affected.
