"PERFORM THE PROCEDURE OUTLINED IN THIS SERVICE INFORMATION ON ALL AFFECTED VEHICLES BEFORE CUSTOMER DELIVERY OR THE NEXT TIME THEY ARE IN THE SHOP FOR MAINTENANCE OR REPAIRS. SUBJECT Service Action: Program Control Units (DSC). In very rare driving situations (distances of more than 310 miles travelled without any DSC, ABS or cruise control/ACC regulation), the DSC return pump is activated in order to initiate internal flushing. When this occurs, it is possible that the pump is not switched off until the engine is turned off. VEHICLES AFFECTED This Service Action involves certain ActiveHybrid models produced from 8/6/2013 to 1/27/2015. First check if a Service Action label with a code number 739 is already attached to the B-pillar. If a code number 739 has been punched out, the Campaign has already been performed and no further action is necessary. Vehicles which require this Service Action to be completed will show it as ""Open"" when checked either in the ""Service Menu"" of DCSnet (Dealer Communication System) or with the Key Reader."
