REPLACE FRONT SAM
This Recall Campaign has been initiated because Daimler AG (DAG) has determined a possible malfunction may occur in the subject vehicles SAM-F
(Signal Acquisition and Actuation Module-Front) due to excess manufacturing stress involving the SAM-F transistors. One transistor in the SAM-F is a
double transistor that helps control three vehicle functions: electrical supply of the windshield wipers, steering wheel adjustment function, and head lamp
operation. A second transistor in the SAM-F helps control the lighting of the center console. A malfunctioning transistor may cause the loss of operation
of the headlamps, windshield wipers and steering wheel adjustment function or the center console lighting. Mercedes-Benz USA, LLC (MBUSA)
therefore has initiated a recall of these vehicles to replace all potentially affected SAM-Fs.
Show in this bulletin is a sample copy of a letter which owners of the affected vehicles will receive.
Prior to performing this Recall Campaign:
^
Please check VMI to determine if the vehicle is involved in the Campaign and if it has been previously repaired.
^
Please review the entire Recall Campaign bulletin and follow the repair procedure exactly as described.
Please note that Recall and Service Campaigns do not expire and may also be performed on a vehicle with a vehicle status indicator.
Approximately 3,283 vehicles are involved.

^
Prior to starting the procedure ensure to:
^
Use DAS 02/08 with all associated patches or higher.
^
Follow the steps exactly as described in DAS.
^
Connect battery charger (battery voltage: >12.5 V). (During front SAM replacement the batteries are disconnected. The charger should
also be disconnected at that time.)
1.
Connect Star Diagnosis to vehicle.
2.
Transfer the settings of the front SAM control module to Star Diagnosis by navigating through the following screen menus: Main Groups/Control
Units/Body/Dr-side SAM - Driver signal acquisition and actuation module (Interior CAN bus)/Initial startup/Initial startup with automatic

Note:
(Regarding SDS on-screen instructions)
