ALL MERCEDES-BENZ CENTERS

SUBJECT:

Model 451, Model Year 2011
Update Electric Drive

This Service Campaign has been initiated because Daimler AG (DAG) has determined that the electric
drive software may not meet current specifications. smart dealers will update the electric drive software at
the next workshop visit.

smart dealers not yet trained or not yet properly equipped with the required tools and equipment
need to direct any smart electric drive vehicle customer to the nearest properly trained and
equipped smart electric drive dealer due to risk of technician personal injury and/or damage to the
vehicle.

Prior to performing this Service 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 Service 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 512 vehicles are affected.

Order No. SM-SC-2011120006
This bulletin has been created and maintained in accordance with MBUSA-SLP S423QH001, Document and Data
Control, and MBUSA-SLP S424HH001, Control of Quality Records.

Procedure
Note:
Work on a electric drive system components may only be conducted by certified workshop personnel
who have completed training courses: Tech 961 and Tech 717.
For the scopes of work described below, the safety regulations and hazard notes apply for work on
high-voltage systems.
Information on this in WIS under AS 54.00-Z-0001-02MEV
WARNING! Risk of death and personal injury may occur
when touching components on vehicles with high-voltage
on-board electrical system if not done properly. Do not
touch components and open lines of the high-voltage onboard electrical system.
Persons who are carriers of electronic implants (e.g. cardiac pacemakers) should not carry
out any work on high-voltage on-board electrical systems due to increased risk of death or
personal injury.
Work on a high-voltage system components may only be conducted by certified workshop personnel. NO
OTHER WORKSHOP PERSONNEL may perform work on the high voltage system.
MBUSA High-Voltage Awareness e-Learning course, TECH717 must be successfully completed before
diagnosing a HV vehicle and proceeding with service has even further requirements. Service work that is not
HV-related, such as tire replacement, can also be done by professionals meeting the same minimum
requirement of high voltage awareness training.
Important! Before the actual update at the vehicle, an update of the Zytek/Tesla diagnostic unit is
first required.
This update must be performed once at the diagnostic unit before the vehicles can be processed as
per the following work instructions (refer to subject A).
The following software versions must be present:
Battery (BMS)
= 1.3.9 (.teslaupdate)
EVCM/EDCM/OS
= 2E1
On-board charger
= 02.** (.teslaupdate)
Tesla Firmware Update Tool
= 2.0.8.81
In order to update the diagnostic unit to the current status, please proceed with the update at the
vehicle as per the instructions in subject A. You can also find additional information in following
documents on smart TekInfo: LI00.30-P-053002, LI00.30-P-053003, LI00.30-P-051650.
